Compressor x modulation:
Configures the type of compressor actuation.
On/Off
: On-off compressor that uses only one digital output (relay) for its actuation.
On/Off 50 I 100:
Compressor that used two digital outputs (relay) for its actuation. The main output, and an auxiliary output in which each output
corresponds to 50% of the compressor capacity.
On/Off 33 I 66 I 100 :
Compressor that used three digital outputs (relay) for its actuation. The main output and two auxiliary outputs in which each output
corresponds to 33% of the compressor capacity.
On/Off 50 I 75 I 100 :
Compressor that uses three digital outputs (relay) for its actuation. The main output corresponds to 50% of the compressor
capacity and each of the two auxiliary outptus corresponds to 25% of the compressor capacity.
On/Off 25 I 50 I 75 I 100:
Compressor that uses four digital outputs (relay) for its actuation. The main output corresponds to 25% of the compressor
capacity and each of the three auxiliary outputs corresponds to 25% of the compressor capacity.
VCC - Analog:
Variable capacity compressor that uses an analog output (0-10V) for its control (available in compressor 01 of each suction line).
Optionally, it is possible to configure a digital output with start / stop function, in the parameter ‘’compressor 1 main output’’ .
Application example:
Compressors using frequency inverters.
VCC - Digital 10-100 1V:
Compressor of variable capacity that uses a main output (relay) for its actuation plus an auxiliary output (SSR) for capacity
modulation. The compressor’s instantaneous capacity is 0% with the auxiliary output on and 100% with the auxiliary output off.
Application example:
Bitzer CRII compressors.
VCC - Digital 10-100 2V :
Variable capacity compressor that uses a main output (relay) for its actuation plus three auxiliary outputs (SSR) for capacity
modulation. The compressor’s instantaneous capacity is 0% with the two auxiliary outputs on, 50% with an auxiliary output on and 100% with the two
auxiliary outputs off.
Application example:
Bitzer CRII compressors.
VCC - Digital 10-100 3V:
Compressor of variable capacity that uses one main output (relay) for its actuation plus three auxiliary outputs (SSR) for
capacity modulation. The compressor’s instantaneous capacity is 0% with the three auxiliary outputs on, 33% with two outputs on, 66% with an auxiliary
output on and 100% with the three auxiliary outputs off.
Application example:
Bitzer CRII compressors.
VCC - Digital 33-100 1V:
Variable capacity compressor that uses a main output (relay) for its actuation plus an auxiliary output (SSR) for capacity
modulation. The compressor’s instantaneous capacity is 33% with the auxiliary output on and 100% with the auxiliary output off.
VCC - Digital 33-100 2V:
Compressor of variable capacity that uses a main output (relay) for its actuation plus two auxiliary outputs (SSR) for capacity
modulation. The compressor’s instantaneous capacity is 33% with the two auxiliary outputs on, 66% with an auxiliary output on and 100% with the two
auxiliary outputs off.
VCC - Digital 50-100 1V:
Compressor of variable capacity that uses a main output (relay) for its actuation plus an auxiliary output (SSR) for capacity
modulation. The compressor’s instantaneous capacity is 50% with the auxiliary output on and 100% with the auxiliary output off.

Compressor 01-06 Activation mode:
Parameter that determines the preferred actuation of the compressor outputs that use auxiliary digital outputs. For more information on the unloader
actuation modes (auxiliary outputs) see section: 14.2 Compressor Modulation.
1.2.x.34
Actuation sequence:
Defines the sequence in which compressors and unloaders are actuated.
0 - PPuu (Actuates compressors first and then unloaders);
1 - PuPu (Actuates a compressor completely before starting another compressor).
1.2.x.35
Shut down sequence:
Defines the sequence in which compressors and loaders are shut down.
0 - PPuu (shut down unloaders fist and then compressors);
1 - PuPu (shut down a compressor completely before starting another compressor).
1.2.x.36
Compressor 01 analog output:
Analog output address of compressor 01. This parameter is available if the compressor modulation is VCC-Analog
0 = Incremental Mode
1 = Unloader Mode
2 = Selective Mode
0 = Not configured
1 = A1
2 = A2
