compressor

A second compressor can be confi gured by setting

 H1 = 12

.

The output controls an ON/OFF compressor using the AUX relay.
The control of the variable-speed compressor follows the diagram shown below.
The fi rst compressor is always the variable-speed compressor.

The variable-speed compressor is managed based on the 
dedicated parameters. If 

H1 = 12 

(AUX = second ON/OFF 

compressor) then 

c1 – c3 

are used for ON/OFF protection of the 

second compressor.

Parameters
