Components
Compressor
The compressor is controlled by the relays of
the control panel on board of the unit.
Compressors are turned on and off according
to the temperatures detected and the tempe-
rature control functions that have been set.
Compressor configuration
The compressor must be connected to
output NO1.
Compressor timing
Compressor start-up and shut-down opera-
tions must comply with the safety times set
by the user using the parameters described
below. A safety period must elapse between
shut-down and start-up of the same com-
pressor (compressor on...off safety time) con-
trolled by parameter Pa C01;
This parameter also applies to when the
device is started up.

Reversing valve
The reversing valve refers to the “heat pump”
operating mode. The reversing valve is off if
the instrument is OFF and on standby.
