Condenser fan control (only with custom set-up)
On hybrid water loop systems an air-cooled condenser is also part of the refrigerant circuit, see Figure 24.

For such a hybrid system, the condenser fan can be congured for one of the outputs via the user dened
applications, and the S7 sensor can be used to control the condenser fan on/o. The S7 sensor is placed on the air-
cooled condenser to measure the condensing temperature. If the measured temperature increases above a set cut-
in limit, the condenser fan is started, and if the temperature decreases with a set dierential, the condenser fan is
stopped again.
Furthermore, a condenser fan override function can be dened for one of the digital inputs, so that the air-cooled
condenser can be used to provide heat to the store if needed.
