Operating instructions

Special Features

Auto Fan

When auto fan is selected the fan speed will vary depending on the

difference between the temperature set-point and the room tempera-

ture. In auto fan the compressor and fan cycle On and Off with the

thermostat.

When the difference is:

>5º The fan operates on HIGH

<4º The fan operates on LOW

Compressor Time Delay

A time delay of approximately two minutes occurs any time the com-

pressor is required to begin the cooling or heat pump cycle.

Defrost Cycle

During heat pump operation, if the outside coil begins to freeze

up, a defrost cycle is initiated that temporarily puts the heat pump

back into air conditioning mode. This reverses the refrigerant ow

and melts the ice forming on the outside coil. Typically this oc-

curs when the outside temperatures are below 42 °F and repeats

every 25 minutes of compressor run time as long as the outside

temperature stays below 42 °F and above 30 °F. Therefore, dur-

ing this period of operation you, (the user) will temporarily feel

cold air inside the RV at the registers. This is normal and is NOT

an indication of malfunction. (Note: Defrost cycling shall con-

tinue until the measured temperature of the Outdoor Sensor is

≤30°For≥42°F.)
