Temperature Compensated Start Cooling Factor (TCS.H) — This factor is used in the equation of the Temperature Compensated Start Time Bias for heating. Refer to the Temperature Compensated Start section for more information. A setting of 0 minutes indicates Temperature Compensated Start in Heating is not permitted. Fan Fail Shuts Downs Unit (SFS.S) — When fan status monitoring is configured on, this configuration will determine whether the unit should shut down on a supply fan status fail or simply alert the condition and continue to run. If set to YES, then the control will shut down the unit and send out an alarm if supply fan status monitoring fails. If set to NO, the control will not shut down the unit if supply fan status monitoring fails but the control will send out an alert. Fan Status Monitoring (SFS.M) — This configuration selects the type of fan status monitoring to be performed. 0 - NONE — No switch or monitoring 1 - SWITCH — Use of the fan status switch 2 - SP RISE — Monitoring of the supply duct pressure. VAV Unoccupied Fan Retry Time (VAV.S) — Machine control types 1 and 2 (VAV-RAT,VAV-SPT) include a process for sampling the return-air temperature during unoccupied periods to prove a valid demand for heating or cooling before initiating an unoccupied heating or cooling mode. If the sampling routine runs but concludes a valid demand condition does not exist, the sampling process will not be permitted for the period of time defined by this configuration. Reducing this value allows a more frequent re-sampling process. Setting this value to zero will prevent any sampling sequence. 50 Hertz Unit? (50.HZ) — This configuration is not used. Do not change the setting of this configuration. MAT Calc Config (MAT.S) — This configuration gives the user three options in the processing of the mixed-air temperature (MAT) calculation: • MAT.S = 0 There will be no MAT calculation. • MAT.S = 1 The control will attempt to learn MAT over time. Any time the system is in a vent mode and the economizer stays at a particular position for long enough, MAT = EDT (evaporator discharge temperature). Using this, the control has an internal table whereby it can more closely determine the true MAT value. • MAT.S = 2 The control will stop learning and use whatever the control has already learned. Using this setting infers that the control has spent some time set to MAT.S = 1. First set MAT.S = 1, then go into the Service Test mode. Turn on the fan and open the economizer to a static position for 5 minutes. Move to several positions (20%,40%,60%,80%). It is important that the difference between return and outside temperature be greater than 5 degrees. (The greater the delta, the better.) When done, set MAT.S = 2. Reset MAT Table Entries? (MAT.R) — This configuration allows the user to reset the internally stored MAT learned configuration data back to the default values. The defaults are set to a linear relationship between the economizer damper position and OAT and RAT in the calculation of MAT. MAT Outside Air Position Default (MAT.D) — This configuration is used to calculate MAT when the economizer option is disabled. The configuration is adjustable from 0 to 100% outside air. This defines the fixed ventilation position that will be used to correctly calculate MAT. 44 Altitude……..In Feet: (ALTI) — As the control does not include a barometric pressure sensor to define the calculation of enthalpy and cfm, the control does include an altitude parameter which will serve to set up a default barometric pressure for use with calculations. The effect of barometric pressure in these calculations is not great, but could have an effect depending on the installed elevation of the unit. If the rooftop is installed at a particularly high altitude and enthalpy or cfm are being calculated, set this configuration to the current elevation of the installed rooftop. Start Up Delay Time (DLAY) — This option inhibits the unit from operating after a power reset. The configuration may be adjusted from 0 to 900 seconds of delay. Auxiliary Relay Output Configuration (AUX.R) — This configuration allows the user to configure the function of the auxiliary relay output. The output is 1.4 vac, 5 va maximum. The configuration can be set from 0 to 3. If AUX.R is set to 0, the auxiliary relay contact will be energized during an alarm. The output can be used to turn on an indicator light or sound an alarm in a mechanical room. If AUX.R is set to 1, the auxiliary relay will energize when the controls determine dehumidification/reheat is needed. The relay would be wired to a third party dehumidification/reheat device and would energize the device when needed. If AUX.R is set to 2, the auxiliary relay will energize when the unit is in the occupied state. The relay could then be used to control lighting or other functions that need to be on during the occupied state. If AUX.R is set to 3, the auxiliary relay will energize when the supply fan is energized (and, if equipped with a VFD, the VFD output is not 0%). The default is 0. Space Temp Sensor (SPT.S) — If a space temperature sensor is installed (T55/T56), enable this configuration. Space Temp Offset Sensor (SP.O.S) — If a T56 sensor is installed with the space temperature offset slider, enable this configuration. Space Temp Offset Range (SP.O.R) — If a space temperature offset sensor is installed, it is possible to configure the range of the slider by adjusting this range configuration. Space Air RH Sensor (SRH.S) — If a space relative humidity sensor is installed, enable this configuration. Return RH Sensor (RRH.S) — If a return air relative humidity sensor is installed, enable this configuration. Filter Status Switch Enabled? (FLT.S) — If a filter status switch is installed, enable this configuration to begin the monitoring of the filter status input (InputsGEN.I FLT.S). See the Dirty Filter Switch section for more details on installation and operation. Cooling Control — The P Series ComfortLink controls offer two basic control approaches to mechanical cooling: multi-stage cooling (CV) and multiple stages of cooling (VAV). In addition, the ComfortLink controls offer the ability to run multiple stages of cooling for either a space temperature sensor or thermostat by controlling the unit to either a low or high cool supply air set point. The control type (Configuration UNITC.TYP) determines the selection of the type of cooling control as well as the technique for selecting a cooling mode. Unit staging tables are shown in Appendix C. NOTE: Whether a unit has a VFD or a supply fan installed for static pressure control has no effect on configuration of the machine control type (C.TYP). No matter what the control type, it is possible to run the unit in either CV or VAV mode provided there are enough stages to accommodate lower air volumes for VAV operation. Refer to the section on static pressure control on page 64 for information on how to set up the unit for the type of supply fan control desired.
SETTING UP THE SYSTEM Machine Control Type (ConfigurationUNITC.TYP) — The most fundamental cooling control configuration is located under ConfigurationUNIT. ITEM EXPANSION RANGE CCN POINT DEFAULTS UNIT UNIT CONFIGURATION C.TYP Machine Control Type 1 - 4 CTRLTYPE * *This default is model number dependent. This configuration defines the technique and control source responsible for selecting a cooling mode and in determining the method by which compressors are staged. The control types are: • C.TYP = 1 (VAV-RAT) and C.TYP = 2 (VAV-SPT) Both of these configurations refer to standard VAV operation. If the control is occupied, the supply fan is run continuously and return-air temperature will be used for both in the determination of the selection of a cooling mode. VAV-SPT differs from VAV-RAT only in that during the unoccupied period, space temperature will be used instead of return-air temperature to start the fan for ten minutes before the return-air temperature is allowed to call out any mode. • C.TYP = 3 (TSTAT – MULTI) This configuration will force the control to monitor the thermostat inputs to make a determination of mode. Unlike traditional 2-stage thermostat control, the unit is allowed to use multiple stages of cooling control and perform VAV style operation. The control will be able to call out a LOW COOL or a HIGH COOL mode and maintain a low or high cool supply air set point. • C.TYP = 4 (SPT – MULTI) This configuration will force the control to monitor a space temperature sensor to make a determination of mode. Unlike traditional 2-stage space temperature control, the unit is allowed to use multiple stages of cooling control and perform VAV style operation. The control will be able to call out a LOW COOL or a HIGH COOL mode and maintain a low or high cool supply air set point. MACHINE DEPENDENT CONFIGURATIONS — Some configurations are linked to the physical unit and must not be changed. The configurations are provided in case a field replacement of a board occurs and the settings are not preserved by the download process of the new software. The following configurations apply to all machine control types (C.TYP). These configurations are located at the local display under ConfigurationUNIT. See Table 32. Table 32 — Machine Dependent Configurations ITEM EXPANSION RANGE CCN POINT DEFAULTS UNIT UNIT CONFIGURATION SIZE Unit Size (30-100) 30 - 100 UNITSIZE * *Dependent on unit. Unit Size (SIZE) — There are 10 unit sizes (tons) for the P Series control. Make sure this configuration matches the size called out by the model number of the unit. This is important as the cooling stage tables are directly determined based on the SIZE configuration. 50 Hertz Unit? (50.HZ) — This configuration is not used. SET POINTS — The set points for both cooling and heating are located at the local display under Setpoints. See Table 33. SUPPLY AIR RESET CONFIGURATION — Supply air reset can be used to modify the current cooling supply air set point. Supply air reset is applicable to control types, C.TYP = 45 1,2,3, and 4. The configurations for reset can be found at the local display under ConfigurationEDT.R. See Table 34. EDT Reset Configuration (RS.CF) — This configuration applies to several machine control types (ConfigurationUNITC.TYP = 1,2,3, and 4). • 0 = NO RESET No supply air reset is in effect • 1 = SPT RESET Space temperature will be used as the reset control variable along with both RTIO and LIMT in the calculation of the final amount of reset to be applied (InputsRSET SA.S.R). • 2 = RAT RESET Return-air temperature will be used as the reset control variable along with both RTIO and LIMT in the calculation of the final amount of reset to be applied (InputsRSET SA.S.R). • 3 = 3RD PARTY RESET The reset value is determined by a 4 to 20 mA third party input. An input of 4 mA would correspond to 0º F reset. An input of 20 mA would correspond to 20º F reset. Configuring the control for this option will cause RES.S to become enabled automatically with the CEM board. To avoid alarms make sure the CEM board and third party input are connected first before enabling this option. Reset Ratio (RTIO) — This configuration is used when RS.CF is set to 1 or 2. For every degree that the controlling temperature (space/return) falls below the occupied cooling set point (OCSP), the calculated value of the supply air reset will rise by the number of degrees as specified by this parameter. Reset Limit (LIMT) — This configuration is used when RS.CF is set to 1 or 2. This configuration places a clamp on the amount of supply air reset that can be applied. EDT 4-20 mA Reset Input (RES.S) — This configuration is automatically enabled when ConfigurationEDT.R RS.CF is set to 3 (third party reset). COOLING CONFIGURATION — Relevant configurations for mechanical cooling are located at the local display under ConfigurationCOOL. See Table 35. Enable Compressor A1 (A1.EN) — This configuration is used to disable the A1 compressor in case of failure for size 30 to 100 units. Enable Compressor A2 (A2.EN) — This configuration is used to disable the A2 compressor in case of failure for size 50 to 100 units. It is always disabled for size 30 to 40 units. Enable Compressor A3 (A3.EN) — This configuration is used to disable the A3 compressor in case of failure for size 90 and 100 units. It is always disabled for size 30 to 75 units. Enable Compressor B1 (B1.EN) — This configuration is used to disable the B1 compressor in case of failure for size 30 to 100 units. Enable Compressor B2 (B2.EN) — This configuration is used to disable the B2 compressor in case of failure for size 40 to 100 units. It is always disabled for size 30 and 35 units. Enable Compressor B3 (B3.EN) — This configuration is used to disable the B3 compressor in case of failure for size 90 and 100 units. It is always disabled for size 30 to 75 units. CSB A1 Feedback Alarm (CS.A1) — This configuration is used to enable or disable the compressor A1 feedback alarm. This configuration must be enabled whenever A1.EN is enabled. CSB A2 Feedback Alarm (CS.A2) — This configuration is used to enable or disable the compressor A2 feedback alarm. This configuration must be enabled whenever A2.EN is enabled.
