For such a hybrid system, the condenser fan can be configured for one of the outputs via the user defined
applications, and the S7 sensor can be used to control the condenser fan on/off. 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 differential, the condenser fan is
stopped again.
Furthermore, a condenser fan override function can be defined for one of the digital inputs, so that the air-cooled
condenser can be used to provide heat to the store if needed.
