0 = Fan related to the compressor status;
1 = Fan independent from compressor.
FA04 Maximum fan speed time after starting request.
If FA02=2 and the condenser fan control is the triac
output, when starting the regulation the trigger output
will drive the condenser fan at the maximum voltage
for the time FA04 then, the regulation will follow the
temperature/pressure of the probe.
If FA04 = 0 this function is not enabled.
FA05 Phase shifting of the fan motor.
Used to compensate the different fan motor. It is
expressed in micro seconds.
FA06 Not used.
FA07 Maximum fan speed time, in Chiller mode,
before switching on the compressor. Used to
compensate the condenser pressure rising value to
get a better regulation.
If FA07 = 0 this function is not enabled.
FA08 Minimum speed for condenser fan in Chiller
mode.
FA09 Maximum speed for condenser fan in Chiller
mode.
FA10 Temperature/pressure value that corresponds
to the minimum condenser fan speed FA08 in Chiller.
FA11 Temperature/pressure value that corresponds
to the maximum condenser fan speed FA09 in Chiller.
FA12 Proportional band for condenser fan control in
Chiller mode.
It allows to set the band within the controller increases
or decreases the fan speed. (default value is the
difference between FA10 and FA11)
FA13 Temperature/pressure differential to stop the
condenser fan in Chiller mode.
FA14 Temperature/pressure differential to keep the
minimum speed in Chiller mode.
FA15 Time delay before activating the CUT–OFF
function after a compressor starting.
If after a compressor starting, the proportional
regulation requires to stop the fan (cut-off) and
FA15≠0, the condenser fan runs at minimum speed
for this time. If FA15=0 the function is not enabled.
FA16 Night function (limited speed) in Chiller
It allows to set a limited speed in Chiller to prevent
noises. To enable it the value must be lower than
FA11.
FA17 Minimum fan speed in Heat Pump Mode.
FA18 Maximum fan speed in Heat Pump Mode.
FA19 Temperature/pressure value that corresponds
to the minimum condenser fan speed in Heat Pump.
FA20 Temperature/pressure value that corresponds
to the Maximum condenser fan speed in Heat Pump.
FA21 Proportional band for condenser fan control in
Heat Pump mode.
It allows to set the band within the controller increases
or decreases the fan speed. (default value is the
difference between Fa19 and Fa20).
FA22 Temperature/pressure differential to stop the
condenser fan in Heat Pump mode.
FA23 Temperature/pressure differential to keep the
regulation with the minimum speed in Heat Pump
mode.
FA24 Night function (limited speed) in Heat Pump
It allows to set a limited speed in Heat Pump to
prevent noises.
FA25 Hot Start Setpoint.
Temperature value detected by Pb2 under which the
supply air fan is stopped.
Only for air/air configuration and heat pump mode.
It starts the fan only if the condenser temperature is
hot enough avoiding cold air flows.
FA26 Hot start differential.
36.7 Anti-freeze, Boiler, integration heater
parameters
Ar01 Anti-freeze: minimum limit for setpoint Ar03 (–40
°C…Ar03)
Ar02 Anti-freeze: maximum limit for setpoint Ar03
(Ar03…110 °C)
Ar03 Anti-freeze Setpoint (range Ar0 …Ar02).
Under this value the controller shows an anti-freeze
alarm:
Pb1 ambient air low temperature for air/air unit,
Pb2 low outlet temperature for air/air unit.
Ar04 Anti-freeze alarm differential. It determines the
alarm reset if temperature is rising.
Ar05 Anti-freeze alarm delay time. It determines the
minimum time, with temperature always lower than
Ar03, before signalling the anti-freeze alarm.
Ar06 Maximum anti-freeze alarm number before
turning to manual reset procedure. After this number
of anti-freeze alarms the controller obliges to execute
a manual alarm reset.
Ar07 Anti-freeze alarm delay time of the outlet air
when starting in Heat Pump mode.
It determines a delay time before signalling the alarm
because the Heat Pump mode will heat the water or
the air. If after this time the temperature is still lower
than Ar03 the unit is immediately turned off.
Ar08 «Anti-freeze heater / integration heater»
Setpoint (air/air unit) in Chiller mode.
Temperature value under which the controller
switches on the anti-freeze heater (with probe NTC
Pb1-Pb2).
Ar09 «Anti-freeze heater / integration heater»
Setpoint for air/air unit in Heat Pump mode.
