Control Function
Compressor Running Compensation
(Demand working with heat pump+
Electric heat)
Temperature differential to activate first
stage auxiliary heat (the GAP of T1
and Ts) Wire controller demand with
heat pump + Electric heat working

Electric heat on delay
Electric auxiliary heating delay to start
time
Compressor/Auxiliary heat outdoor
ambient lockout
Set outdoor temperature Limitation (for
auxiliary heating or compressor)
Maximum continuous runtime allowed
before system automatically stages up
capacity to satisfy set point. This adds
1 to 5°F to the user set point in the
calculated control point to increase
capacity and satisfy user set point

The compressor will not operate if the
outdoor temperature is lower than the
temperature represented by S3
0 means that the temperature
protection is not turned on, the dial
range is 1 through F, 1 equals -4°F
and it increased up to 46°F

Available settings are 000/001/010/
011. Each digit corresponds an
individual switch position. For
example [SW4-1 OFF, SW4-2 ON,
SW4 -3 OFF] = 010. See table 11 for
the corresponding CFM adjustment
