1 Introduction The iPro HVAC and Lighting controller (P/N 818-9004) is a lighting and HVAC control board standalone controller. iPro HVAC and Lighting is capable of controlling heat and cool stages, fans, and economizers using on-board I/O and control algorithms. The iPro HVAC and Lighting supports local physical inputs and outputs. 1.1. The iPro HVAC and Lighting’s I/O Points The iPro HVAC and Lighting supports 15 relay outputs, 6 analog outputs, 10 analog inputs, and 20 digital inputs.
2 Mounting and Powering There are no restrictions on the location of the iPro HVAC and Lighting controller (all local electrical code laws should be followed). The controller should be mounted in a location/environment that stays within a 20 to 85% relative humidity range (as specified by the label on the enclosure). 2.1. Installation The iPro HVAC and Lighting uses a DIN mount installation. Figure 2-1 - DIN Mounting 2.1.1.
2.2.1. Choosing Transformer Sizes The transformer used to power the iPro HVAC and Lighting should have at least a 20VA rating. The iPro HVAC and Lighting should not share a transformer with any other devices. transformer to the iPro HVAC and Lighting. Shielded cable should not be used for power wiring. The center tap should be left disconnected, if present on the transformer.
3 Network Addressing Visograph The network address makes a board unique from other boards on the network of the same type. This allows the site controller to find it and communicate with it easily. The network address of the iPro HVAC and Lighting is set using add-on devices called visographs (P/N 318-7272). 3.2. Visograph Navigation From the visograph, you can: • Set MODBUS address • Configure Lighting • Configure HVAC In order to enter the configuration, press keys 1, 3 and 8. 3.1.
4 Input and Output Setup 4.1. Wiring Analog Inputs The iPro HVAC and Lighting provides separate input commons depending on the type of sensor connected. For temperature probes, all commons should be wired to PbC on terminal 7. For voltage output transducers, all commons should be wired to GND on terminal 8. The analog inputs are located on the same connector as the controller power supply.
CAUTION! Mis-wiring a sensor to the wrong common can result in damage to the iPro HVAC and Lighting Controller. Terminal Number on Connector CAUTION! Any inputs that are powered with a voltage that differs from that supplied by the iPro HVAC and Lighting (+12V or +5V) must be powered separately with another transformer in order to prevent the inputs from malfunctioning or being damaged. Do not use the same secondary of the controller's power to power the sensors.
The iPro HVAC and Lighting provides a maximum of 20 opto-insulated digital inputs. However, only the first ten inputs are currently used (see Table 4-2). All digital inputs are voltage-free and are intended to have dry contact devices connected.
4.3. Wiring Digital Loads The digital output relays are located across four separate connectors along the top side of the iPro HVAC and Lighting. Figure 4-7 - Digital Load Connectors The normally-open relay outputs on each connector share the same common and are not fused. Make sure to use the same voltage for all loads connected to the relays.

Wiring Analog Outputs The analog outputs are located on a separate 12pin connector. Figure 4-9 - Analog Outputs Connectors The iPro HVAC and Lighting provides six optoisolated analog outputs. Because the analog outputs are opto-isolated, they must be separately powered by a 24V supply. The power supply can be 24VAC/DC.

5 iPro HVAC and Lighting Status LEDs When an iPro HVAC and Lighting board is powered up, you will be able to determine the operating status of the board by observing its status LEDs. Figure 5-1 -iPro HVAC and Lighting Status LED Locations PWR ON LED The PWR ON LED stays on continuously to show that the board is powered and operational. If this light is off, the board has likely lost power.
6 Software Overview The IPro for HVAC and Lighting and retail stores controls inside, outside lighting and HVAC units. The lighting control has up to 5 zones assigned, (which represents one relay per zone). They drive the lights using schedules, light levels, overrides, and a combination of schedule and light level. The HVAC control manages up to 2 cool and 2 heating stages plus a fan output (in total 5 outputs per unit). The application runs two units on the main iPro board.
6.1.2. Slave Schedule Control The application supports up to 5 Slave schedules, 1 for each lighting relay output, (which represents one relay per zone). Each one needs to have all days of the week available and up to 3 schedule events per day for user configuration. The time will be in 12 hr format entered as a relative time. Meaning, it will be added or subtracted to the schedule event that corresponds to the corresponding day in the Master schedule. The resolution will be 10 minutes.
6.2.2. Inside Lighting Control 6.2.2.1. Inside lighting control has four different ways of controlling: In dimming mode, the application works with the internal light level sensor to lower linearly as the light level increases. The mode has four parameters, which are the end points (define the endpoint of the dimming output). The dimming output has a rate of change to the analog output from short cycling. • Dimming Control. • Schedule Only. • Schedule and Light Level Combination.
6.2.2.4. Logic Input 6.2.3.2. In Logic Input mode, the relay output will come on only if the override input reads an ON signal. Also, if logic input is defined as an override and the inside lights control is in any other mode of operation (Dimming, Schedule-only, Schedule, and Schedule and Dimming combination), the logic input will have priority and turn on the relay output. The application has the ability to switch the polarity of the digital inputs.
the unit with the active input will stop its cooling or heating, fan, and economizer control (disables the unit). The HVAC Control temperature values will support Dixell and CPC sensors in both Fahrenheit and Celsius engineering units. 6.3.1.
ture. However, if both temperatures fail in the Average Temperature mode, the backup will then become the return temperature.
6.3.2.4. Cooling Control Strategy The cooling application will control up to two stages of cooling. If the application is set for one stage, it will turn the cooling relay output on when the control temperature is above the setpoint plus ½ deadband. It will turn off when the control temperature is below setpoint minus ½ deadband.
Occupied mode is generally the time of day when a store is open. In this mode the HVAC unit will operate with the occupied setpoint. Unit 1 Parameter Unit 2 Parameter Description Unoccupied mode is generally when a store is closed. In this mode the HVAC unit will operate with the unoccupied setpoint.
Relay Out Function Becomes (H/C Mode) → → → → → Cool 1 Cool 2 HT 1 HT 2 The setpoints are divided between occupied and unoccupied; these will be toggled from the Master Schedule in the Lighting Control application. Heat Pump Mode (HP Mode) Occupied mode is generally the time of day a site is open to the public or “occupied;” the time is set in the master schedule. In this mode the HVAC unit will operate with the occupied setpoint.
6.3.5. Economizer Control For Economizer Control there are two separate parameters, for HVAC1 and HVAC 2. Economizer control will operate the outside damper in Free Cooling mode or by indoor air quality, whichever requires the most. For Free Cooling in Cooling Mode, the damper observes any lockout to heating and cooling. IAQ will always have priority over lockout and operates normally. Note that Free Cooling is enabled in Cooling Mode, and IAQ is enabled when the CO2 probe is configured.
6.3.5.2. Indoor Air Quality There are two separate IAQ Control for HVAC1 and HVAC2 which are same CO2 sensor. The Indoor Air Quality Control will share its input with the return temperature on each HVAC unit. If IAQ is required, the use of the return sensor would not be available. The application will use a CO2 reading and endpoint parameters to produce a linear output. If one of the two Return Probes are configured for C02, this probe is shared between the two units.
The unit for the Delay of Probe error Alarm has to be entered in seconds, not minutes.
