Each compressor needs three relay outputs:
One relay output as Line #1 of the compressor #1 (Relay K1 of the Fig.3).
One relay output as Line #2 of the compressor #1 (Relay K3 of the Fig.3).
One relay output as centre of the star (Relay K2 of the Fig.3)
To turn on the compressor: the centre of the star relay is turned on (Relay K2 of the Fig.3), after 1 second the Line #1 relay is turned on
(relay K1 Fig.3). The two relays work together for the time set in CO11, then the relay of centre of the star is switched off (relay K2
Fig.2). Then after the CO12 delay time the relay of the line #2 is turned on (relay K3 Fig.3).
To turn off the compressor: The output relay of the line #1 and line #2 are switched off together.

OMPRESSOR
If one or more capacity compressors are configured and the thermoregulation requires the full load control, the controller turns the
solenoid valve on, then after 1 second the centre of the star relay is turned on (relay K2 Fig. 3). Then the star-delta procedure will be
completed with the other two contactors. Durning the CO13 time delay the step valve is forced on: minimum power. When the C013 is
expired if the thermoregulation requires more power the valve will be switched off (maximum power).
28 CAPACITY CONTROL
CO06 capacity control operative mode.
The relay configured as capacity control are managed by the thermoregulation as shown in the graph and into the tables here below.
Par CO06 = 0 ON/OFF step
0= Step control. Depending on the thermoregulation requests and the output polarity a power step can be enabled or disabled. The step
is activated only after the previous is turned off.
Eg: # 1 capacity compressor with 3 partializations: 4 Power steps.

Par CO06 = 1 direct action with sequential step
1= the steps are turned on in sequential mode, the outputs are anabled or disabled depending on the output polarity. In case of
thermoregulation request one of the step is turned on or off while the other steps do not change their status.
Eg: # 1 capacity compressor with 3 partializations: 4 Power steps.
