If the temperaTure/pressure decreases under the set rC06-rC07 (differential) the recovery cycle, of the circuit detected by that
transducer , is anabled again.

ISABLED
To avoid long periodof time with recovery function disabled and the temperature/pressure within the range rC06-rC07, the units starts
counting the delay set in rC08. After this delay if the decreasing temperature is still within the rC06-rC07 range, the recovery cycle is
forced on again.
41 MESSAGES - ALARM CODES
the alarm codes are defined by letters and numbers:.
Alarm typology:
•
A = alarm of the unit
•
b = alarm of the circuit
•
C = alarm of the compressor
41.1 AP1 - AP2 - AP3 - AP4 - AP5 - AP6 - AP7 - AP8 - AP9 - AP10 - AP11 - AP12
PROBE FAILURE
Label on display AP1 = PB1 probe alarm… AP10 = PB10 regulator probe alarm
AP11 keyboard N° 1 probe alarm
AP12 keyboard N° 2 probe alarm
Reason Probe configured but the read-out is not in the range
Reset Probe not configured or probe in the right range
Restart Automatic
Icon
blinking
Action Alarm Relay + and buzzer on
41.2 AEFL:
EVAPORATOR FLOW ALARM
(
DIFFERENTIAL
P
RESSURE SWITCH
)
Label o the display AEFL
evaporator flow alarm
Origin
Available only for air/water - water/water units
Digital input active for the time set in AL15 after the water pump is on and, after the digital input
itself is activated, for the time set in AL17.
Reset
Digital input not active for the time AL18.
Restart Automatic – Manual after AL16 events per hours (Reset procedure in Menu function).
Icon
Blinking
Action Alarm Relay + and buzzer on only during normal running conditions.
41.3 ACFL:
CONDENSER FLOW ALARM
(
DIFFERENTIAL
P
RESSURE SWITCH
)
Label o the display
ACFL condenser flow alarm
Origin Available only for air/water - water/water units
Digital input active for the time set in AL15 after the water pump is on and, after the digital input
itself is activated, for the time set in AL17.
Alarm not enable if AL14=0
Alarm enabled in chiller only if AL14=1
Alarm enabled in heat pump only if AL14=2
Alarm enabled in chiller and heat pump if AL14=3
Reset Digital input not active for the time AL18.
Restart Automatic – Manual after AL16 events per hours (Reset procedure in Menu function).
Icon
Blinking
Action Alarm Relay + and buzzer on only during normal running conditions.
ATTENTION
The alarm relay and the buzzer are activated only if the alarm appears during normal running conditions.
When the temperature setpoint has been reached and CO16/CO21= 2, the icon
blinks without alarm.
NOTE ABOUT THE FLOW ALARM
CO16 / CO21=0
Water pump not enabled.
The alarm is managed only if one digital input is configured as flow switch, the restart is always automatic.
CO16 / CO21=1 Water pump with continuous control.
The alarm is managed only if one digital input is configured as flow switch, the restart is always automatic, in stand–by or remote
OFF ( pump off), it becomes manual after AL16 events per hour.
In chiller or heat pump only. During the functioning of the unit any flow alarm stop the loads described in the table, the water pump
follow its regulation algorithm and is turned off, after AL16 events per hours it is completely locked.
