HEATING
Parameter CH = HT; The value HY has been preset to 2 K at the factory.
If the temperature falls below the value SET-HY, the controller output will be
switched on and will be switched off again when SET is exceeded.

2.4 Controlling the loads
CONTROLLER OUTPUT
The regulation is dependent on the measured temperature (= sensor
temperature). You can program the control direction (heating or cooling) with
the parameter CH.
CH = CL Cooling
CH = HT Heating
COOLING
Parameter CH = CL; The value HY has been preset to 2 K at the factory.
If the temperature exceeds the value SET+HY, the compressor will be
switched on, and SET will be switched off again with temperature undershoot.
