P-13: Reverse Automatic Fan Speeds During Heating

The automatic fan speeds can be reversed during Heating Mode. The fan will
speed up as the set point is approached. Lowering the fan speed when the
cabin is cold increases head pressure and helps raise supply temperature.
The fan switches to low speed when the set point is satisfied and the com-
pressor cycles off.

Normal fan operation is represented by “nor”.

➤ To reverse fan speeds in heating, select “rEF”.

P-14: Cycle Fan with Compressor

The fan can be programmed to run continuously when the system is on or
can be allowed to cycle with the compressor.

The default is “con”, continuous fan.

➤ To cycle the fan with the compressor select “CYC”.

NOTE
When used with optional electric heat the fan will remain on 4 min
after the heater cycles off.

P-15: Reverse Cycle or Electric Heat

➤ Do not change the default parameter.

P-16: Fan Motor Selection

NOTE
The unit’s High Velocity (HV) blower has a Split Capacitor (SC) fan
motor. For this motor this parameter must be changed from “SP” to
“SC” in order for the blower to work at peak efficiency.

➤ Select “SC”.
➤ Save this change as a new default by simultaneously pressing and releas-

ing the Up and Down Buttons prior to exiting the program mode.

➤ Make note of new default in the Programmable Parameters table for

future reference and servicing.
