36 LOAD MAINTENANCE
PARAMETERS CO26..CO31 are the set of the running hour counters of the compressors.
They establish, for each load, the number of running hours limit to display a maintenance message.
If one of these parameters is equal to 0 the maintenance signalling is disabled but the running hours counter remains active.

Loads Not modified
The parameters CO32 / CO33 define the hour set counters for the evaporator water pump / Support
evaporator water pump / Supply fan.
They establish the load running hours limit of the pump/s or the supply fan to give a maintenance signalling. If one of these parameters
is equal to 0 the maintenance signalling of that load is disabled but the running hours counter remains active.
37 CONDENSER FAN REGULATION
The FA01 and FA02 parameters define the operative mode of the condenser fans. The CF68 and CF69 selects which are the output
signals.
Par.
CF68 Condenser fan control signal of the circuit #1
0= 0 ÷10V
1= 4÷20mA
2= PWM
Par.
CF69 Condenser fan control signal of the circuit #2
0= 0 ÷ 10V
1= 4÷20mA
2= PWM
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 Fan operative mode
0 = Fan on only if compressor on
1 = Independent from the compressor, off during the stand–by / or from remote OFF
Parameter combination
FA01 – FA02
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
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 the fans are thermoregulated depending on the condensing
temperature/pressure.
Par.
FA01 = 3 + Par. FA02 = 0
Fans on, with ON/OFF continuos 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 = 3 + Par. FA02 = 1
Fans on, with ON/OFF continuos 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 the fans are thermoregulated depending on the condensing
temperature/pressure.
Par.
FA01 = 4 + Par. FA02 = 0
Fans on, with proportional regulation (PWM, 4..20mA, 0.10V) and with temperature/pressure transducer control, only when the
compressor is on. When the compressor turns off also the fans are forced off.
Par.
FA01 = 4 + Par. FA02 = 2
Fans on, with proportional regulation (PWM, 4..20mA, 0.10V) and with temperature/pressure transducer control, only when the
compressor is on. When the compressor turns off the fans are thermoregulated depending on the condensing temperature/pressure.
