5. Press the ▼ key to change the °C or °F indication.
NOTE: Stage-one heat and cool cycle rates are fixed at 
3 cph. Only stage-two heat cycle rates are 
selectable.
6. Press the ▲ key to display the heat cycle rate of 3, 
4, 5, 6, 9 or 12. If the desired cycle is displayed, 
see Table 1, press the ▲ key to exit the installer 
setup mode. To change the heat cycle rate, press 
the ▼ key to scroll between 3, 4, 5, 6, 9, and 12. 
Stop scrolling when the desired rate is displayed.

figuration default.
8. Press the ▲ key again to change cooling algorithm 
to C1 or C3.
C1 = Standard cooling algorithm.
C3 = Aggressive cooling algorithm (can cause 
overshooting).
9. Press the ▲ key again. Current configuration (CC) 
is displayed. A typical example is shown, but CC 
varies by model. (This information is for factory use

CHECKOUT
Heating
1. Slide the SYSTEM switch to Heat and the FAN 
switch to Auto.
2. Press and hold the ▲ key to raise the temperature 
setting several degrees above the room tempera-
ture. After approximately five minutes, the heating 
equipment should start.
3. Press the ▼ key to lower the temperature setting 
below the room temperature. Heating equipment 
should stop.
Cooling
CAUTION
Equipment Damage Hazard.
Operating at too low of an outdoor 
temperature may cause compressor damage.
Do not operate cooling if outdoor temperature is 
below 50°F (10°C). Refer to manufacturer’s 
recommendations. 
• For compressor protection, allow the 
compressor to remain off for five minutes 
before restarting.
1. Slide the SYSTEM switch to Cool and the FAN 
switch to Auto.
2. Press the ▼ key to lower the temperature setting 
several degrees below the room temperature. After 
approximately five minutes, the cooling equipment 
and fan should start.
3. Press the ▲ key to raise the temperature setting 
above the room temperature. Cooling system 
should shut down.
