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.

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
