CO07
“Water pump / air supply fan” switch off delay
time after compressor deactivating.
Having CO11 = 2 (“water pump / air supply fan”
related to compressor on/off status), the “water pump
/ air supply fan” always stops after the compressors.
Having CO11 = 1 (continuously running of pump/fan)
the relay switches off when the controller turns to
stand-by mode.
CO08
Compressor control sequences.
0 = Compressor rotating sequence.
Depending on the number of running hours the
controller enables the compressor with less counted
running hours. The switch off sequence stops the
compressor with greater number of running hours.
Rotating sequence is not enabled for units having a
compressor with a stage.
1 = Fixed sequence control.
Compressor_1 always starts before Compressor_2
and stops always after Compressor_2 stops.
In case of compressor_1 alarm the compressor_2
immediately stops.
CO09
Reserved.
CO10
Stage polarity valve.
0 = stage active for valve ON (relay closed);
1 = stage active for valve OFF (relay open).
CO11
“Water pump / air supply fan” relay
configuration.
0 = Relay not configured..
1 = Continuously running. The relay switches on when
the controller is turned to Chiller or Heat Pump mode.
2 = “water pump / air supply fan” is related to
compressor on/off status (par CO06 , CO07
activated).
CO12
Compressor_1 off line for maintenance.
0 = ON; 1 = OFF
If set to OFF, the compressor is not more included
into the regulation and the relay output will never be
turned on. To include the compressor this parameter
must be set to 0.
CO13
2
nd
compressor or stage off line for
maintenance.
0 = ON; 1 = OFF
If set to OFF, the compressor is not more included
into the regulation and the relay output will never be
turned on. To include the compressor this parameter
must be set to 0.
CO14
Alarm setpoint for compressor n°1 running
hour.
Number of compressor running hour before signalling
the warning alarm A13. If 0 the function is not
enabled.
CO15
Alarm setpoint for compressor n°2 running
hour. Number of compressor running hour before
signalling the warning alarm A14. If 0 the function is
not enabled.
CO16
Alarm setpoint for pump/fan running hour.
Number of pump/fan running hour before signalling
the warning alarm A15. If 0 the function is not
enabled.
36.6
Ventilation parameters
FA01
It enables the condenser fan output.
0 = Not enabled;
1 = Enabled.
FA02
It selects, with parameter FA03, the type of
condenser fan regulation.
0 = (with FA03=0) fan ON with compressor ON.
0 = (with FA03=1) fan ON but independent from
compressor and Off in stand –by.
1 = (with FA03=0) fan ON with compressor ON
following the ON/OFF regulation of the condensing
temperature/pressure trend.
When compressor goes OFF also fan goes OFF.
1 = (with FA03=1) fan ON/OFF following the
condensing temperature/pressure trend.
2 = (with FA03=0) fan ON when compressor ON with
proportional regulation (triac and 4..20mA outputs)
based on condensing pressure/temperature trend.
When compressor goes OFF also fan regulation goes
OFF.
2 = (with FA03=1) fan ON/OFF with proportional
regulation (triac and 4..20mA outputs) based on
condensing pressure/temperature trend.
FA03
Condensing fan and compressor status.
