Machine Control Type (C.TYP) — This configuration defines
the technique and control source responsible for selecting
a cooling, heating, or vent 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 in the
determination of the selection of a cooling or heating 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 10 minutes to establish
an accurate return-air temperature before the returnair
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 VAVtype
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-type 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.
Unit Size (SIZE) — There are several 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.
Fan Mode (FN.MD) — The Fan Mode configuration can be
used for machine control types (Configuration
UNITC.TYP) 3, and 4. 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 3 and 4. This switch can be
used for several remote control functions. Please refer to the
43
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 configurations,
this option will be set to Yes automatically.

Temperature Compensated Start Cooling Factor (TCS.C) —
This factor is used in the equation of the Temperature Compensated
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.
