Table 33 — Unit Configuration

Fan Mode (CV.FN) — The Fan Mode configuration can be

used for machine control types (Configuration

UNIT

C.TYP) 3, 4, 5, and 6. The Fan Mode variable

establishes the operating sequence for the supply fan during

occupied periods. When set to 1 (Continuous), the fan will

operate continuously during occupied periods. When set to 0

(Automatic), the fan will run only during a heating or cooling

mode.
Remote Switch Config (RM.CF) — The remote switch input

is connected to TB201 terminals 1 and 2. This switch can be

used for several remote control functions. Please refer to the

Remote Control Switch Input section for details on its use and

operation.
CEM Module Installed (CEM) — This configuration instructs

the control to communicate with the controls expansion module

(CEM) over the local equipment network (LEN) when set to

Yes. When the unit is configured for certain sensors and configu-

rations, this option will be set to Yes automatically.

The sensors and configurations that automatically turn on

Temperature Compensated Start Cooling Factor (TCS.C) —

This factor is used in the equation of the Temperature Compen-

sated Start Time Bias for cooling. Refer to the Temperature

Compensated Start section for more information. A setting of

0 minutes indicates Temperature Compensated Start in Cooling

is not permitted.
Temperature Compensated Start Cooling Factor (TCS.H) —

This factor is used in the equation of the Temperature Compen-

sated 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) — 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 mon-

itoring 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 con-

trol 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 rou-

tine runs but concludes a valid demand condition does not ex-

ist, 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.
Unit Size (SIZE) — There are several unit sizes (tons) for the

Z 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 both

the SIZE and 50.HZ configurations.
