Compressors
enabling
P1
Compressor 1 N/Y Y Compressor 1 circuit 1. Allows to deactivate manually one compressor Compressor 1B N/Y Y Compressor 2 circuit 1 (dependent on unit configuration)
P2
Compressor 2 N/Y Y Compressor 1 circuit 2 (dependent on unit configuration) Compressor 2B N/Y Y Compressor 2 circuit 2 (dependent on unit configuration)
Electrical heaters enabling
P3
Elec. heater 1 N/Y Y
Only displayed if the electric heaters are present in the unit (option)
Elec. heater 2 N/Y Y
Temperature
setpoint limit
P4
High °C 0 30,0 35,0
Allows to limit the summer and winter setpoints in the setpoint and clock sections, in
addition to the 2°C limitation of the winter setpoint towards the summer one.
Low °C 0 12,0 35,0
Temperature
regulation
P5
Regulation type P/PI P
Choice of the regulation type for the compressors: P (proportional) or PI (Proportional Integral)
Integration constant s 0 600 1800 Integral constant for PI. Be careful when modifying this parameter.
P6
Summer °C 0 2,0 15,0
Temperature regulation band that corresponds to the proportionnal parameter in the
P or PI summer regulation. See the Compressors control part.
Winter °C 0 2,0 15,0
Temperature regulation band that corresponds to the proportionnal parameter in the
P or PI winter regulation
Dead zone °C 0 0 3,0
Divided by 2, this parameter is the value above or below the setpoint (in summer or winter mode) to start compressors regulation. See the compressors control part.
Humidity
setpoint limit
P7
High %rH 0 80,0 99.9
Allows to limit the summer and winter humidity setpoints in the setpoint section.
Low %rH 0 20,0 99.9
Dehumidification P8
Enabling N/Y N (option) Differential %rH 0 5,0 20,0
See the Dehumidification part.
Dead zone %rH 0 0 10,0
Fan speed management
P9
Decrease if setpoint reached
N/Y Y If the setpoint is reached, save energy by lowering fan speed
