Determines the length of time the compressor must remain active after
being switched on, even if the request ceases.

Minimum compressor OFF time
Determines the length of time the compressor must remain deactivated
even if a request is transmitted for it to switch on again. During this stage,
the LED pertaining to the compressor will flash.

Activation delay between 2 compressors/steps
With two compressors this establishes the start-up delay between the
two, to reduce absorption at peaks. During this stage, the LED pertaining
to the compressor will flash. (only for the compressor)
With units with partialised compressor. This determines switch-on time of
the unloader solenoid for start-up at minimum capacity (see
compressors start-up)

in temperature control (start-up with minimum capacity / idle start-up
valve in OFF with compressor off)

(start-up with minimum capacity / idle start-up valve in ON with
compressor off)

Start-up is part-winding or star-delta
If CO12 = 1 part - winding start-up time applies. This allows you to vary the
attachment of the two relays that supply the two motor coils.
If CO12 = 2 star triangle start-up time applies. This allows you to vary the
simultaneous operation time of the line 1 relay and the relay that closes the
star centre connection. (see start-up par.)
