2 Main Control Logics
2.1 Cooling
2.1.1 Control to the Compressor
When the unit is controlled by the leaving water temperature, the compressor operating frequency will be
adjusted according to the temperature difference in direction proportion. (Temperature difference= actual leaving
water temperature-leaving water temperature set point).
2.1.2 Freeze Protection
When it is detected that the leaving water temperature of the plate heat exchanger is lower than the freeze
protection temperature, the compressor will drop its operating frequency until it reaches the minimum operating
frequency. Then if it is still detected that the leaving water temperature is lower than the freeze protection
