IMPORTANT: The computer system software (ComfortVIEW™, Service Tool, etc.) that is used to interact with CCN controls always saves a template of items it considers as static (e.g., limits, units, forcibility, 24-character text strings, and point names) after the software uploads the tables from a control. Thereafter, the software is only concerned with run time data like value and hardware/force status.

Setting IAQ.L to OPEN means that when the switch is open the input will read LOW.
mode. The System mode is the top level mode that defines three essential states for the control system: OFF, RUN and TEST. The HVAC mode is the functional level underneath the System mode which further defines the operation of the control. The Control mode is essentially the control type of the unit (Configuration→UNIT→C.TYP). This defines from where the control looks to establish a cooling or heating mode and whether 2 stages or multiple stages of cooling capacity operation are controlled.
HVAC Mode — COMP.STUCK ON — The unit is shut down because there is an indication that a compressor is running even though it has been commanded off. HVAC Mode — TEST — The unit is in the self test mode which is entered through the Service Test menu. HVAC Mode — VENT — This is a normal operation mode where no heating or cooling is required and outside air is being delivered to the space to control IAQ levels. HVAC Mode — HIGH COOL — This is a normal cooling mode where a high cooling demand is required.

VAV Cool Mode Selection during the Occupied Period (C.TYP = 1,2 and Operating Modes→MODE→OCC =ON) — There is no difference in the selection of a cooling mode for either VAV-RAT or VAV-SPT in the occupied period.
Demand Level Low Cool Off Offset (L.C.OF) — This is the cooling set point offset subtracted from “cooling set point plus L.C.ON” at which point a Low Cool mode ends. NOTE: The “high cool end” trip point uses the “low cool off” (L.C.OF) offset divided by 2. To enter into a LOW COOL mode, the controlling temperature must rise above [the cooling set point plus L.C.ON.] To enter into a HIGH COOL mode, the controlling temperature must rise above [the cooling set point plus L.C.ON plus H.C.ON.
3 compressor unit, if no compressors are currently on, compressor A2 is currently under a minimum off compressor timeguard, and 2 compressors are to be turned on, then compressors A1 and B1 will be turned on immediately instead of A1 and A2. Low Cool Versus High Cool Mechanical Staging — The number of compressors to be requested during a cooling mode are divided into 2 groups by the control, HVAC mode = Lo Cool and HVAC mode = Hi Cool.
Table 37 — 2-Stage Sequence — 48/50AJ,AW020-027 EDT Low Override — There is an override if EDT drops too low based on an alert limit that will lock out cooling. If the supply air/evaporator discharge temperature (EDT) falls below the alert limit (Configuration→ALLM→SA.L.O) cooling will be inhibited. There is a 20-minute hold off on starting cooling again once the following statement is true: EDT minus (Run Status→COOL→SUMZ→ADD.R) has risen above SA.L.O. The variable ADD.

Head Pressure Control Operation — The following logic describes the head pressure control routine when any compressor has been commanded on. When the compressor has been commanded on, then condenser fan A will be energized (CD.F.A = ON). If the highest active circuit SCT is above the HPSP, then condenser fan B will be energized (CD.F.B = ON). If the OAT is above 75 F, then both condenser fans A and B will be energized (CD.F.A = ON and CD.F.B = ON).
(Configuration→HEAT→OC.EN). See descriptions above in the Setting Up the System section for more information. If the unit is allowed to select a heat mode, then the next step is an evaluation of demand versus set point. At this point, the logic is the same as for control types SPT Multi-Stage and SPT-2 Stage, (C.TYP = 5,6) except for the actual temperature compared against set point. See Temperature Driven Heat Mode Evaluation section. Tstat-Multi-Stage (C.TYP = 3) and Tstat-2 Stage (C.

HT.CF = 3 (Staged Gas Heating Control) — As an option, the units with gas heat can be equipped with staged gas heat controls that will provide from 5 to 11 stages of heat capacity. This is intended for tempering mode and tempering economizer air when in a cooling mode and the dampers are fully closed. Tempering can also be used during a preoccupancy purge to prevent low temperature air from being delivered to the space. Tempering for staged gas will be discussed in its own section.
units there will be one IGC board. On size 030-050 high heat units and 060 low heat units there are two IGC boards. On size 060 high heat units there are three IGC boards. When a call for gas heat is initiated, power is sent to W on the IGC boards. For standard 2-stage heat, all boards are wired in parallel. For staged gas heat, each board is controlled separately. When energized, an LED on the IGC board will be turned on. See Table 56 for LED explanations.

conditions. For example, a system design requirement may be 1.2 in. wg, the equipment may be capable of providing 3.0 in. wg and the supply duct is designed for 5.0 in. wg. In this case, the installer could enter 3.0 in. wg as the supply static pressure set point and allow the air terminal system to dynamically adjust the supply duct static pressure set point as required.
Table 60 — Dirty Filter Switch Points Fan Status Monitoring GENERAL — The A Series ComfortLink™ controls offer the capability to detect a failed supply fan through either a duct static pressure transducer or an accessory discrete switch. The fan status switch is an accessory that allows for the monitoring of a discrete switch, which trips above a differential pressure drop across the supply fan.

CONTROL CURVE A B C D Configuring the economizer for Unoccupied Economizer Free Cooling is done in the UEFC group. There are three configuration options, FC.CF, FC.TM and FC.LO. Unoccupied Economizer Free Cooling Configuration (FC.CF) — This option is used to configure the type of unoccupied economizer free cooling control that is desired. 0 = disable unoccupied economizer free cooling 1 = perform unocc. economizer free cooling as available during the entire unoccupied period. 2 = perform unocc.
Fig. 9 — Custom Changeover Curve Example ECONOMIZER DIAGNOSTIC HELP — Because there are so many conditions which might disable the economizer from being able to provide free cooling, the control has a display table to identify these potentially disabling sources. The user can check ACTV, the “Economizer Active” flag. If this flag is set to Yes there is no reason to check DISA (Economizer Disabling Conditions).

Smoke Control Modes — There are four smoke control modes that can be used to control smoke within areas serviced by the unit: Pressurization mode, Evacuation mode, Smoke Purge mode, and Fire Shutdown. Evacuation, Pressurization and Smoke Purge modes require the Controls Expansion Board (CEM). The Fire Shutdown input is located on the main board (MBB) on terminals TB5-10 and 11.
The logic that is used to control the dampers in response to IAQ conditions is shown in Fig. 10. The ComfortLink control will begin to open the damper from the IAQ.M position when the IAQ level begins to exceed the OAQ level by a configurable amount, which is referred to as Differential Air Quality Low Limit (DAQ.L). If OAQ is not being measured, OAQ can be manually configured. It should be set at around 400 to 450 ppm or measured with a handheld sensor during the commissioning of the unit.
