Cooling Control with Flow Temperature Sensor

Depending on the P-band (CLTC-01), the integral and the differential times (CLTC-02 and CLTC-03), the cooling valve will be modulated as function of the cooling flow temperature control deviation.

The cooling pump will start with the start-up delay defined in parameter CPMP-01:

The cooling pump will stop:

The cooling pump will stop after switch off delay defined the setting CPMP-02.

The cooling controller will not control if the outside air temperature is below the low limit cooling set in the macro “SWM_SummerWinterMode” (HVAC_Mode<3). The room controllers which are connected via the communication signal "ApplicModeXL10" or “ApplicModeIRM will stop in this case.
