32. LOAD MAINTENANCE
It is possible to define for each load (compressors and water pumps) the number of working hours after witch
the display will show a maintenance warning.
Parameters CO26..CO29: number of working hour of the compressors
Parameters CO32..CO33: number of working hour of the evaporator water pump
Parameters CO34..CO35: number of working hour of the condenser water pump
Parameters CO73: number of working hour of the sanitary water pump
Parameters CO74: number of working hour of the solar panel water pump
Parameters CO95: number of working hour of the free cooling water pump
If the parameter is set to 0, the maintenance signalling is disabled but the running hours counter remains
active.
33. CONDENSER FAN REGULATION
The signal to drive the modulating condenser fan is available in the Out 1...Out 4analog outputs:
• OUT 1 and OUT 2 are 0..10V
• OUT 3 and OUT 4 are 0..10V or PWM selectable by parameter CF49
FA01 and FA02 parameters define the operative mode of the condenser fans.
Par. FA01 Fan regulation
0 = Output not enabled
1 = Always on
2 = ON/OFF step regulation
3 = ON/OFF continuous step regulation
4 = proportional fan speed
Par. FA02 Condenser fan operation mode
0 = Fan on only if compressor on
1 = Independent from the compressor and off during the stand–by / or from remote OFF
Example:
Par. FA01 = 1 / Par. FA02 = 0
Fans on when the compressor on (the fans work following the same output algorithm)
Par. FA01 = 1 / Par. FA02 = 1
Independent from the compressor status but off in stand–by.
Par. FA01 = 2 / Par. FA02 = 0
Fans on, with ON/OFF regulation and with temperature/pressure transducer control, only when the
compressor is on (at least one relay is configured as fan control). When the compressor turns off also the
fans are forced off.
Par. FA01 = 2 / Par. FA02 = 1
