2 Hardware Overview This section gives an overview of the E2, the hardware, and how it communicates across the I/O and Echelon Networks to control an entire system. 2.1 E2 Hardware The E2 controller is programmed to monitor and command all aspects of a refrigeration or building environmental control system. The E2 uses both an RS485 I/O Network and a LonWorks Network to gather data from input devices, communicate with other E2s, and activate or deactivate loads.
2.1.1 (CPU) E2 Main Processor Board 2.1.3 E2 Keypad Figure 2-4 - E2 Keyboard Figure 2-2 - E2 CPU (RX-100 Version Shown) The E2 CPU or main processor board (Figure 2-2) contains the CPU, Ethernet port, and memory used for logging. The 3.6V battery for the E2 is located on this board and protects log and alarm data during power loss. The main processor board connects to the PIB via a ribbon cable. The RX- and CX-100 versions support monochrome display only.
Main Board (CPU) LEDs Status Green (D1 General Status LED for E2 and Blank Face E2) 1 blink every two seconds (1 second ON, 1 second OFF): Main board is operating normally. Solid ON: E2 is booting up. Faster blinks per second: Indicates an error condition with the hardware or firmware. Green (D18 Boot Status LED) ON: E2 is booting up. Table 2-3 - Main Board (CPU) LED’s Status Keyboard LED Status Green (D5 General Status LED) 1 blink every two seconds (1 second ON, 1 second OFF): Status is normal.
The Gateway board is an RS485 to RS485 converter. One side of the Gateway is always connected to the Retail Solutions I/O Network. The other side of the Gateway is the receiver bus (RS485). The receiver bus is connected to one or more RS485 devices depending on which type of Gateway is being used. The Gateway interfaces devices to the Einstein/E2 and legacy Retail Solutions controller (REFLECS) by simulating 16AI and 8RO boards using Retail Solutions standard I/O board protocol.
The MultiFlex 16 is designed with several features that make it easy to install, wire, and configure. These main user interface features are shown in Figure 2-7. The MultiFlex combination I/O boards consist of up to 16 combination digital/analog inputs, and a combination of relay outputs, digital outputs, and analog outputs. 2.2.2.
810-3066 MultiFlex 168 16 analog/digital inputs, 8 relay outputs. 810-3067 MultiFlex 168DO 16 analog/digital inputs, 8 relay outputs, 4 digital outputs 810-3072 MultiFlex 1616L 16 analog/digital inputs, 16 low-voltage (24VAC rated) relay outputs 810-3073 MultiFlex 1616LAO 16 analog/digital inputs, 16 low-voltage (24VAC rated) relay outputs, and 4 analog outputs.
2.2.2.3 MultiFlex CUB The MultiFlex Condensing Unit Board (CUB) is a “smart” input/output board designed to control single condensing units. A single condensing unit is a self-contained compressor and condenser bearing unit which controls refrigeration in a single case line-up or walk-in cooler. The MultiFlex CUB uses the same general hardware configuration as a MultiFlex 168AO.
The PAK can control up to 4 condenser fan groups containing up to 8 total condenser fans. The PAK condenser control strategy is sequential TD control with setpoint/deadband using ON and OFF delays. The PAK has a compressor/condenser interlock feature that will override TD control and force the condenser fans to stage off using the TD control OFF delay when all compressors are off. This feature can be disabled with an Enable/Disable setpoint or when the discharge pressure is above a configurable setpoint.
• CCB and CC-100 case controllers The HHT does not require a separate power source. The unit is powered from the RJ-11 connector on the peripheral equipment. The HHT includes a standard male RJ-11 to male RJ-11 cable. NOTE: The 9V battery and 9-12V DC adapter connection are not used on this HHT model (P/N 814-3110). 1 with any refrigeration system or environmental control component. The 8RO board is the direct link between the E2 and component operation.
2.2.6 4AO Analog Output Board The 4AO Analog Output Board (P/N 815-3030) (Figure 2-13) is configured with four analog output connections that provide a variable voltage signal to any of four analog devices that may be controlled by a single E2. Two 4-20mA outputs are provided for channels 1 and 2. The 4-20mA outputs provide a variable current for applications that are either externally powered or that require power from the 4AO board. 9 2.2.
2.3 Echelon Network Boards and Peripherals 2.3.1 The 16AIe (Discontinued) board similar in function to its I/O Network counterpart, the 8RO. The 8ROe board is the direct link between the E2 and component operation. Information gathered by the controller from the input boards is checked against current stored setpoints. If differences in the received input data and the setpoint information are detected, a signal is either sent to the proper 8ROe relay, or an existing signal is discontinued.
floor managers of alarms and notices. Other lights on the display show the ON/OFF status of refrigeration, defrost, and fans. The EC-2 can be easily programmed using either the four front-panel buttons or an optional infrared remote control. For security, the buttons can be disabled to prevent tampering. NOTE: There are several variations of the EC-2. Contact Retail Solutions at 1-800-8292724 for more information. 2.3.
2.3.7 Facility Status Display (FSD) Figure 2-21 - ESR8 Board Layout 2.3.6 TD3 Temperature Display The TD3 is a digital display unit designed to show both case temperature and product temperature for a refrigerated store case or walk-in freezer. The TD3 mounts on the front of a case and connects to up to three input devices (a case temperature sensor, a product temperature probe, and either a defrost termination probe or thermostat).

8 Echelon Network and Hardware Setup 8.1 Overview Echelon is an optional, two-conductor network that interconnects E2s and other associated devices, such as CC-100 case controllers, TD3 temperature displays, and ESR8 evaporator stepper regulator boards. All Echelon devices are wired together using the daisy-chain method of network structuring.
multiple routers can be used to extend the network indefinitely. More information about routers and how they are used in a daisy-chain Echelon Network can be found in the Router and Repeater Installation Guide (P/N 026-1605). RECOMMENDED E2 E2 8.4 UNBROKEN CHAIN E226513125rev Device Termination In a daisy-chain configuration, both ends of the network segment must be terminated. Terminate the E2 by setting jumper JP7 to the UP position, as shown in Figure 8-3.
8.4.1 Using a Termination Block (P/N 535-2715) to Terminate a Daisy Chain a maximum of 63 more nodes. Some Echelon Network devices, notably TD3s, have no on-board means of terminating. For some other devices, it is inconvenient to use the jumpers supplied for termination (the CC-100/CS-100 case controllers, for example, require the enclosure to be removed to set the jumper). Refer to the Router and Repeater Installation Guide (P/N 026-1605), for information about router and repeater placement.

10.17 Set Up Global Data Setup screen. The Global Data feature is an enhanced method of effectively distributing commonly used input values between multiple E2s. Sensors such as outdoor temperature and outdoor humidity are set up on an E2 as Global Data inputs. This E2 then becomes the “provider” of the global sensor values to all other Global Data applications on the E2. As a result, a single sensor can be used by any application in any E2 on the network.

The secondary provider would then stop sending the secondary value, and all Global Data applications would use the primary value. If using this priority setting, you must enter board and point settings. Example: Out of three E2s, an outside air temperature sensor on E2 A’s I/O Network is set up as the primary provider of the global Outside Air Temp input.

11 Software Overview 11.1 Suction Groups 11.1.1 Introduction The E2 RX refrigeration controller uses suction group applications to cycle compressors in an effort to maintain a constant suction pressure or temperature in a refrigeration system. A suction group may contain up to 16 compressor stages (standard, variable-speed, or unloader).
cycled ON or OFF. Unlike the Suction Group application, which uses a PID percentage to determine how many stages to turn ON or OFF, the Enhanced Suction Group keeps historical data of the effects each compressor stage has on the suction pressure or temperature, and analyzes that data to determine which stages to cycle. The Enhanced Suction Group application is designed to balance tight control of suction pressure with economic management of compressor cycling to reduce power usage and compressor wear. 11.

The refrigerant temperature is subtracted from the value of an ambient air temperature sensor. The result is the temperature differential. It is this differential value that is compared to the PID setpoint for the purpose of determining the amount of total fan capacity to activate. 11.2.2 Evaporative Condensers In an evaporative condenser, water is sprayed across a condenser coil, which cools the refrigerant as water is evaporated.

The enthalpy of the outdoor air is calculated and compared to the enthalpy of the indoor air. If the outdoor air enthalpy is less than the indoor air enthalpy, economization is enabled. Otherwise, economization is disabled. The dehumidification setpoint is placed at the 0% end of the dehumidification PID throttling range.
11.6.11 Separate Setpoints comfortably within the range of the new setpoint. UNOCCUPIED PRE-STOP (COAST) OCCUPIED UNOCCUPIED SET POINT PRE-START OCCUPIED SET POINT UNOCCUPIED Figure 11-15 shows an example of how pre-starts and pre-stops work in a heating application. From unoccupied mode, the pre-start period ramps the temperature up slowly so that when the scheduled change from unoccupied to occupied mode occurs, the temperature will already be at or near the occupied heating setpoint.

11.7.2 How Zones Work A Zone is built by first creating a Zone application in the E2 BX. Then, all HVAC unit applications that will be a part of the Zone must be connected with the Zone application. This connection process is known as association. When a rooftop unit or AHU is associated with a Zone, the E2 automatically makes a series of I/O connections between the Zone application and the individual MultiFlex RTU or AHU application.
ever, if desired, an AHU may be associated with a Zone application, which will allow the AHU to use the Zone’s setpoints, occupancy state, summer/winter state, and dehumidification and economization enabling. 11.7.4 Temperature Control As mentioned, Zone applications do not “control” temperature themselves. Zone applications simply pass along the setpoints an HVAC unit will use, and the individual unit is responsible for controlling to the setpoint using its own temperature input.
11.7.8 The Effect of Enabling Economization Both MultiFlex RTU and AHU applications support the use of both two-position (digital) and variable-position (analog) economizers. Digital economizers, when enabled, behave like a first stage of cool. When analog economizers are enabled, the MultiFlex RTU or AHU will modulate the opening percentage of the dampers based on its own mixed air temperature measurements. 11.7.
26512036 Figure 11-17 - Diagram of Pre-Start and Pre-Stop Operation Intelligent Pre-Starts and Pre-Stops OSS is designed to handle pre-starts and pre-stops in the most energy-efficient manner possible. Every time a pre-start or pre-stop occurs, OSS measures the amount of time it takes to bring the temperature from the previous setpoint to within the “comfort zone” of the new setpoint (a user-defined range of values above and below the setpoint within which the temperature is considered acceptable).
11.9 MultiFlex PAK Board The PAK is a distributed pack (rack) controller that controls compressors and condenser fans. The PAK can control up to 8 compressor groups containing up to 16 compressors. The compressor control strategy is Fixed Steps with setpoint/deadband using ON and OFF delays. Up to 20 Fixed Steps can be configured. The PAK can control up to 4 condenser fan groups containing up to 8 total condenser fans.
setpoints, and overrides the schedule as the real-time lighting conditions warrant. As a result, the light level sensor and schedule both work to provide adequate light when needed AND saving energy by keeping lights OFF when they are not necessary. 11.10.
state, when both the light level state and the LOGIC IN input are ON, the resulting output command will be ON. The output command will remain ON until both the light level state and the LOGIC IN input turn OFF. • Both ON/LLEV OFF - Like the Both ON/ Both OFF strategy, except only the light level state must turn OFF in order to turn the output from ON to OFF. • LLEV ON/Both OFF - Like the Both ON/ Both OFF strategy, except only the light level state must turn ON in order to turn the output from OFF to ON.
11.10.6.1 Slave Scheduling TIP: Activating the Use Alt Control parameter is the only way to use the Solar Calculation Control method for Lighting Control. 11.10.5.2 Offset Solar Control The Offset Solar Control cell of the Lighting Schedule application uses the Sunrise Offset and Sunset Offset parameters to determine how many minutes before or after sunrise the sun is considered to be risen, or how many minutes before or after sunset the sun is considered to be set.
longer than the programmed proof delay, the Proof cell turns its Proof output ON to signify a failure has occurred. The Proof cell will deactivate the Proof output if the proof failure has been cleared longer than the programmed proof latch time. 11.10.9 Output Light Dimming The dimming feature allows the lighting output to be varied based on a light level sensor. Dimming capability can work with both Standard Control and Alternate Control configuration.
As mentioned in Section 11.11.1, Introduction to Demand Limit Control, all KW input values are gathered together and averaged together in a demand window. The demand setpoint is then subtracted from this average. The result of this calculation is called the integral error (or integral) of the demand window. The integral error represents how far below or above the setpoint the input has been for the entire demand window.
significant effect on the system if it were to be shed for a prolonged period of time. Examples: motor room exhaust fans, satellite HVAC units and/or lights in low-occupancy rooms. BEGIN SHEDDING 2. Rotational Shed The Rotational Shed levels are shed in sequence only if all defined First Shed levels have already been shed and the Demand Control application needs more shedding to lower demand.
11.11.6 How Demand Control Uses Load Shedding Demand Control uses three parameters to perform load shedding: the current KW input value, the current integral error (described in Section 11.11.2, Demand Monitoring), and the active KW setpoint. The active setpoint is chosen from four different setpoint values depending on the season (summer or winter) and occupancy (occupied or unoccupied). The Demand Control application is programmed with three different “modes” of operation.
loads. 11.11.6.1 Power Monitoring Input The Input Type Selection parameter defines the way the Power Monitoring input (INPUT under the Inputs tab in application Setup) will be used. The parameter can be set to: KW Analog, or Pulse KWH. 11.12.3 Cut In/Cut Out Setpoint Control Cut In/Cut Out setpoints work differently depending upon whether the Cut In/Cut Out setpoint is higher.
basic functions: • LOGICAL COMBINATION: Up to four inputs may be combined using standard logical combination methods (such as AND, OR, XOR, etc.) The result is the command output value, which can be used to operate a relay. • BYPASS: The command output may be configured to be bypassed to a fixed value by a switch or button press. • ALARMING: Alarms and notices can be generated based on the command value of all the digital inputs of the cell, plus occupancy, and schedules. 11.12.
stage outputs. The Sequencer supports up to eight cells, and also provides for minimum on/off times and first-on/ last-off sequencing. being sent to the outputs, replacing it with a fixed value specified by the user. The value from the Override cells is then sent to the Loop/Sequence Control’s PID output, and also to the two output cells for conversion to stages and PWM. PWM - The PWM cell drives a digital output whose ON time per pulse width modulation period is equal to the PID percentage.
of the Occupancy input. If you wish to follow a schedule for occupancy, this input must be tied to the output of a Time Schedule application. 11.13.2.2 The Setpoint Float Cell The Setpoint Float cell provides users to raise and lower the control setpoint based on the value of a sensor (called the “float” sensor).
stant period of time that consists of one ON event and one OFF event. The PWM cell takes the PID percentage and turns the output ON for an equivalent percentage of the total pulse period. In other words, if the PID output is 60% and the pulse period is 30 seconds, every 30 seconds the PWM output will be ON for 60% of 30 seconds (18 seconds) and OFF for the remaining portion of the 30-second period. Once the period has ended, the PWM Cell reads the PID output again and the process is repeated.
occur weekly or annually). KW usage in a building. 11.14.1.4 Overlapping 11.15.1 Overview Events may, and often do overlap within a schedule. When events overlap, the E2 uses the following priority structure, from highest to lowest: Explanation of “Demand” 1. Temporary Schedule Event #1 2. Temporary Schedule Event #2 3. Temporary Schedule Event #3 4. Events that occur on HD1 (Holiday #1) 5. Events that occur on HD2 (Holiday #2) 6. Events that occur on HD3 (Holiday #3) 7.
NOTE: If you do not wish to use load shedding for your building, simply do not connect anything to the SHED OUT output. 11.15.2 Logging Power Monitoring applications are pre-programmed with extensive logging capabilities that record the hourly, daily, and monthly power usage statistics. Hourly The hourly log contains a list of power usage summaries of the previous 48 hours.
11.16 Anti-Sweat Setup An anti-sweat application controls one anti-sweat zone. An anti-sweat zone is defined as one or more antisweat heaters that use the same dewpoint (or RH and temperature) sensors and the same control setpoints. If all the outputs on a 20-channel PMAC panel are going to use the same setpoints and dewpoint device(s), then all the heaters may be set up in a single zone. Zones are set up in a single screen called the AntiSweat Control Setup screen. 11.16.
UNOCCUPIED HYSTERESIS PRE-STOP (COAST) UNOCCUPIED SET POINT OCCUPIED OCCUPIED SET POINT PRE-START pied setpoint. UNOCCUPIED drops to the Unoccupied Heating Setpoint or rises to the Unoccupied Cooling Setpoint, the heat or cool outputs go to 100% ON. They remain in this state until the temperature rises above the heating setpoint plus the hysteresis, or below the cooling setpoint minus the hysteresis, at which time the outputs will go to 0% ON.
As the value of the reset sensor varies within the minimum and maximum range, an equivalent portion of the maximum setpoint adjustment will be added or subtracted from the heating or cooling setpoint. When the reset sensor value is directly in between the minimum and maximum range values, nothing will be added or subtracted from the setpoint. Between the halfway point and the minimum value, part of the setpoint adjustment will be subtracted from the setpoint.
must be used. A Multiple Input cell is a simple application that reads data values from its inputs, combines them using a userdefined combination strategy, and sends the combined value to the desired application input. A common application for this is in HVAC control, where a single heating control value might come from an average of a number of temperature sensors throughout the building.
drop leg temperature rises above this setpoint, the condenser fans are cycled ON regardless of the value of the TD. The Drop Leg Offset setpoint is an adjustment entered, if needed, after measuring liquid subcooling during operation of an individual condensing unit. The TD setpoint is the optimal difference between the refrigerant drop leg temperature and the ambient (plenum) temperature. When the TD (i.e.
total accumulation, and the last accumulated total information can be viewed. The current output shows the rate of consumption of the quantity represented by pulses. Average output shows the average rate value accumulated over the period set in the Average Window parameter. The High Limit Trip output will turn on if the total accumulation exceeds a userspecified high limit. Total accumulation shows the total accumulated value since the last reset.
11.21.2.1 Cycle Control Types By default, Timed cycles are always used unless the user has configured a flow sensor (optional). If a flow sensor is configured, a control type parameter will become visible where the user can select either a Timed or Volume cycle control type. During any cycle, the disabled zone states and valve outputs will be set to OFF. For midnight crossover times, a cycle will be completed if the duration extends into the next day. 11.21.2.
11.21.5.1 Bypass Failsafe While each zone is bypassed to ON, a timer is checked. If time has elapsed equal to or greater than the zone’s cycle duration parameter, the bypass input will be ignored and the zone will return to normal operation. For a zone in Bypass Failsafe, its bypass input must be set to OFF or NONE to reset the Bypass Failsafe and to use the bypass input again. 11.21.6 Flow Sensor-Related Tests 11.21.6.

If for any reason the algorithm thinks that the high speed and the low speed should both be ON, the highspeed fan should be turned ON only. 11.23 Modular Chiller Control (MCC) Proper fan speed should be set when there are no heating or cooling stages ON, and the Fan Always On Setpoint is enabled. 11.21.
Figure 11-1 - Compact Chiller System 11.23.2 Learning Mode 11.23.4 Compressor Control When an MCC application runs for the first time, it undergoes a "Learning Mode" period to collect data on the chiller stages. During Learning Mode, the MCC will control the chilled water temperature, but it will purposely cycle the chiller stages in different combinations to measure the effect they have on the temperature input value.
11.23.4.1 Digital Scroll Compressor MCC can also utilize a single Digital Scroll Compressor. The assumption is that one of the Compressor Control Modules in the system may have a digital scroll instead of a standard scroll compressor installed. The Digital Scroll Compressor may not be the same size as the fixed scroll compressors.
11.25 Refrigerant Monitoring System (RMS) The RMS enables the E2 ability to measure the refrigerant used to add, remove and repair an asset that has a refrigerant charge. RMS is available for E2 versions 3.01 and above. The RMS comes with two components that are installed together, the RMS asset and the RMS scale. A total of 99 RMS applications can be supported by the E2. The RMS is a licensed application. For licensing instructions, refer to the software licensing section (see Section 10.

Appendix D: PID Control Introduction to PID Control PID Control is a specialized method of closed-loop control that strives to maintain equality between an input value and a user-defined setpoint by operating a device or a number of devices at somewhere between 0% and 100% of full capacity. PID Control works by making adjustments to the output at a constant rate called the update rate (usually 2-6 seconds).
Throttling Range on page D-1. . THROTTLING RANGE OUTPUT AT SETPOINT (shown here as 50%) If Proportional Mode is functioning incorrectly in your system, it may be more appropriate for you to change the Throttling Range value to a more appropriate value. Kp is designed as a fine-tuning constant (for example, it might be used to speed up reaction slightly by setting it to 1.04, or to slow down reaction by setting it to 0.98).
TEMPERATURE TEMPERATURE S E T P O I N S T E T P O I N T TIME TIME “P” + “I” MODES “P” MODE ONLY Figure D-2 - Comparison of “P” Mode vs. “P” + “I” Mode Saturation Once the input value has wandered outside Proportional Mode’s throttling range, the output percentage will be at 0% (if below the Throttling Range) or at 100% (if above the Throttling Range).
sate for error. the case temperature equal to the temperature setpoint. To reduce this lag time, Derivative Mode is used. Derivative Mode constantly analyzes the rate of change of the error, makes a prediction about what the future error will be, and makes an adjustment to the output in an attempt to reduce the rate of change in the error. Condenser Control and HVAC Control seek only to keep pressure or temperature values below or above their setpoints.
THROTTLING RANGE OUTPUT AT SETPOINT (shown here as 50%) point, the output percentage is dropped from 50% (it is assumed this will result in the input rising back to the setpoint). Likewise, when the input is higher than the setpoint, the output percentage is raised. For Condenser Control PID, no reaction is made to an input that is lower than the setpoint, since the output percentage is already 0%.
are 20% and 100% respectively, the output percentage will never be below 20%, even if the P, I, and D Mode adjustments call for the output to be below 20%. The output will remain in saturation at 20% until a higher output percentage is called for. trolled by PID control. Valve filtering is active in this CC100, with the filter period set to six seconds and the filter percentage set to 75%.

Appendix F: Troubleshooting The chart below describes symptoms and solutions if troubleshooting the system or equipment is needed. For further information, contact Retail Solutions Service at 1-800-829-2724. SYMPTOM POSSIBLE PROBLEM SOLUTION I/O Network Problems I/O board not getting power. Check I/O board power--is the green STATUS light on? If not, check power wiring connections, and use a multimeter to verify the board is getting 24VAC. Reset power to board.
SYMPTOM Echelon Network Problems F-2 • E2 RX/BX/CX I&O Manual POSSIBLE PROBLEM SOLUTION Faulty wiring. Check connections. Are wires broken or loose? Check network polarity (positive to positive/ negative to negative). Check for wire damage. Termination jumpers are set incorrectly. Check for proper setting of terminating resistance jumpers. Network segment should be terminated on the two endpoints of the daisy chain and unterminated everywhere else. Refer to Section 8.4, Device Termination.
SYMPTOM Compressor will not Operate POSSIBLE PROBLEM SOLUTION Compressor is not programmed properly. Verify that E2 was programmed for correct number of compressor stages. Highlight the General tab (C1) in the Suction Group Setup screen. Is the correct number of stages in the “Number of Stages” field? Compressor types are set up incorrectly. Make sure that compressor stages were properly set up as VS (variable speed), C (compressor), or U (unloader). Compressor programmed with incorrect rating.
SYMPTOM Compressor will not Operate (Cont.) F-4 • E2 RX/BX/CX I&O Manual POSSIBLE PROBLEM SOLUTION 8RO fail-safes are not wired correctly. Verify fail-safe wiring on 8RO board for N.O./N.C. positions. One wire of the two-wire connection should always be connected to the middle terminal. The second wire must be either connected to the N.C. terminal (if you want the relay to be closed (ON) during power failure) or the N.O. terminal (if you want the relay to be open (OFF) during power failure.
SYMPTOM Problems with Condenser POSSIBLE PROBLEM SOLUTION Condenser will not operate. Verify that E2 is programmed with proper number of fans. 1. Highlight the General tab (C1) in the Condenser Setup screen. 2. Is the correct number of fans in the Number of Fans field? Incorrect board and point settings. Confirm proper board and point settings: Go to the Inputs tab (C3) in the Condenser Setup screen to check PRES CRTL IN and DISCH TRIP IN. Fail-Safe wiring on 8RO is incorrect.
SYMPTOM Problems with Cases Problems with Global Actions F-6 • E2 RX/BX/CX I&O Manual POSSIBLE PROBLEM SOLUTION Case will not go into hot gas or cool gas defrost. Check Group LLSV in Suction Group setup: 1. Go to the Outputs tab (C5) on the Suction Groups Setup screen and check GROUP LLSV. 2. Verify that the case(s) is assigned to the correct group. Case will not terminate out of defrost mode. 1. Verify the termination type (Term Type) in the Defrost tab (C4) in the Standard Circuits Setup screen.
SYMPTOM Problems with Temp Sensor or Pressure Transducer Displaying Proper Value POSSIBLE PROBLEM SOLUTION 16AI input dip switches are set improperly. The 16 dip switches on the 16AI board correspond to each of the inputs: Dip Switches Up = Temperature Sensor Dip Switches Down = Pressure Transducer Incorrect board and point address. Set proper board and point settings for both input and output: Go to the Inputs tab in the application’s Setup screen and check Board and Point. Incorrect sensor type.
SYMPTOM Dehumidification Problems Lighting Control Problems POSSIBLE PROBLEM SOLUTION Number of stages are not set up or set up incorrectly. From the Home screen, press (AHU), (SETUP). Move cursor to C9 (Dehum) to check Dehum Stages. Dehumidifier source not set up. From the same screen, verify what the sensor source is. Temperature setting for DEHUM OCC or DEHUM UOC is set too high. From the same screen, check the minimum temperature setting. Lights will not come on.
