Description of functionality

Compressor operation

Runtime A 1min forced runtime of the compressor is executed.
protection
If the HP/LP pressure switch is activated the compressor will stay off for 5 min-
utes.

Condenser fan operation

High / low The condenser fan is running whenever there is a need for cooling, and it is able
speed to run at two different speeds.
/
When the compressor starts it will activate the condenser fan to run for at least
one minute at low speed. The condenser fan will switch into high speed if the
condenser coil temperature is exceeding 60 [°C]. It will switch to low speed again
when the temperature is decreased to 57 [°C].
If the return air temperature decreases to 17 [°C] the compressor will stop even
though it has been running less than three min. This will force the condenser fan
to stop after one minute. The condenser fan will also stop if the condenser tem-
perature drops to below 35 [°C]. This will take place until the condenser tem-
perature exceeds 35[°C] again.
35°C

Heater operation

The heater is turned on and off by the control board according to the set point-
see table above in the section: Set points.

Internal fan operation

Always The purpose of the internal fan is to circulate the internal air, and therefore the
running internal fan will constantly be running when the power supply is turned on.
