dGty Kind of digital compressor
SCrL =
Digital Scroll: the range of capacity modulation starts from 10% to 100%
StrM =
Digital Stream: the range of capacity modulation starts from 0% to 100%
StP
Valve outputs (unloader) polarity:
polarity of the outputs for capacity valves. It
determines the status of the relays associated with the capacity valves (only for
homogeneous and stepped-capacity compressors)
oP
= valve activated with open contacts of the relay.
cL
= valve activated with close contacts of the relay.
FtyP
Refrigerant type
: set the kind of gas refrigerant used in the plant:

Sty
Compressors rotation enabling
YES
=
rotation enabled
: this algorithm distributes the working time between the various
compressors to ensure even run times.
no
=
fixed sequence
: the compressors are enabled and disabled in fixed sequence: first,
second etc.
NOTE:
The
digital scroll compressor
is always started as first and switched off as last.
In any case, if it is locked because of safety timers, it can be started to maintain
the pressure in the regulation band. See par. dGSP
rot
Activation: type of sequence
YES
= rotation: this algorithm distributes the working time between the various loads to
ensure even run times.
no
= fixed sequence: the compressors are enabled and disabled in fixed sequence: first,
second etc.
NOTE:
The
digital scroll compressor
is always started as first and switched off as last.
In any case, if it is locked because of safety timers, another compressor is started
to maintain the pressure in the regulation band.
