6.7 Miscellaneous controls
6.7.1 Inverter configuration (compressors/fans)
If selected, the inverter is always the first compressor in each circuit:
⋅ 1 Circuit: the inverter (if enabled) is compressor 1
⋅ 2 Circuits: the circuit 1 inverter (if enabled) is compressor 1, and the circuit 2 inverter (if
enabled) is the first compressor configured on the second circuit
⋅ 3 Circuits: the circuit 1 inverter (if enabled) is compressor 1, the circuit 2 inverter (if
enabled) is the first compressor configured on the second circuit, and the circuit 3 inverter
(if enabled) is the first compressor configured on the third circuit
The inverter is included in the number of compressors or fans configured by parameter for
each circuit.
Example 1
1 Circuit
Compressor inverters YES
5 Compressors
0 Steps
Fan inverters NO
3 Fans
Example 2
1 Circuit

3 Fans
Example 1 configuration parameters:
CircuitNumber 1
Enable Circuit 1 Compressor Inverter YES
Number of Compressors for Circuit 1 6
Number of Compressor Steps 0
Enable Circuit 1 Fan Inverter NO
Number of Fans for Circuit 1 3
Example 2 configuration parameters:
CircuitNumber 1
Enable Circuit 1 Compressor Inverter NO
Number of Compressors for Circuit 1 5
Number of Compressor Steps 2
Enable Circuit 1 Fan Inverter NO
Number of Fans for Circuit 1 3
Depending on the single/dual/triple-circuit version, there are limitations on the use of inverters:
Single-circuit:
⋅ One compressor inverter (Analogue output 1)
⋅ One fan inverter (Analogue output 3)
Dual-circuit:
⋅ Two compressor inverters (Analogue outputs 1 - 2)
⋅ Two fan inverters (Analogue outputs 3 -4)
Triple-circuit:
⋅ Three compressor inverters (Analogue outputs 1 – 2 - 3) or
⋅ Three fan inverters (Analogue outputs 1 – 2 - 3)
⋅ Three compressor inverters (Analogue outputs 1 - 2 - 3) and one fan inverter (Analogue
output 4) in the case of unique condensation
In the case of the triple-circuit version, the inverters are exclusive: it is only possible to select those
pertaining to compressors, or those pertaining to fans. Management of a combination of both types
