℉ vs ℃ Display

The unit is factory configured to display all temperatures in degrees Fahr-

enheit (

℉

). To switch to degrees Celsius, press the “UP” and “DOWN”

buttons simultaneously for three seconds. The display will switch to C

degrees. To revert back to

℉

, press the “UP” and “DOWN” buttons simul-

taneously for three seconds. The display will switch to F degrees.

Cooling Mode

Pressing the “Cool” button after turn the unit on will put the unit into cool-

ing mode. Press “UP” or “DOWN” button to adjust the set point, the unit

will cycle the compressor on and off to maintain a comfortable room. The

compressor will cycle on anytime that the room temperature is 2

℉ above

the set point. The fan will either continuous or cycling, depends on the “Constant

Fan” selection. See Constant Fan section.

Heating Mode

After turn on the unit, press the “Heat” button will put the unit into heating

mode.

Heat Pump Models(PZH)

When the “Heat” button is pressed initially the unit may call for heat pump

or electric strips (depends on different ambient temperature or DIP Switch

4 settings) to bring the room to the set point. When the room temperature

falls 2

℉

below the set point, the unit will cycle the compressor or electric

strip on. The fan will either continuous or cycling, depends on the “Con-

stant Fan” selection. See Constant Fan section. When the outdoor coil

temperature falls below 26

℉

for 3 minutes, the unit will operate the elec-

tric strip instead of heat pump. Only when the room temperature reaches

the set point and the outdoor coil temperature rises to 36

℉

, the com-

pressor will be allowed to operate again.

Fan” selection. See Constant Fan section.

Emergency Heat Operation

In the event of a compressor failure in heat pump mode, the compressor

may be locked out to provide heat through the electric strip heater. This

feature ensures that even in the unlikely event of a compressor failure,

the room temperature can be maintained until the compressor can be

serviced. Dip switch 2 controls the emergency heat setting.

Constant Fan

Pressing the “Constant Fan” button will provide constant or cycle fan

operation in cooling or heating modes. The fan speed selection is made

by pressing either “High” or “Low” or “Auto” fan speed button.
