– ACF11 CONFIGURATION ALARM OF THE UNIT
Label on the display
ACF1
• Heat pump unit without 4-way valve not configured
• Wrong configuration of defrost parameters dF22/23
ACF2
• Condensing control without probe configuration.
(one probe per circuit with 2 separate circuits, at least 1 probe for common cond.)
• Wrong configuration of the parameters for fan proportional control:
FA09 + FA11 + FA12 < FA10
FA12 < FA13
FA07 < FA15 < FA08
• Wrong configuration of the parameters for fan proportional control and pump enabled:
FA18 + FA21 + FA20 < FA19
FA21 < FA22
FA16 < FA23 < FA17
• Wrong configuration of the parameters for fan ON/OFF control:
FA09 < FA10
• Wrong configuration of the parameters for fan ON/OFF control and pump enabled:
FA18 < FA19
• Evaporating/condensing probes not configured in heat pump unit and defrost enabled.
• Unit with condenser fan drived by triac regulation (CF43, CF44 = 8/9) and the power supply
configuration is Vcc (CF54 = 1…4)
• In case of fan management in ON/OFF mode:
Chiller: step1<step2<step3
Heat pump: step3<step2<step1
ACF3
• Two digital/analogue inputs configured as the same function or without the necessary
resources (es. compressor # 1 overload but compressor#1 relay not configured)
ACF4
• CF52 = 1 and its digital input not configured or CF52 = 2 and no external temperature probe
configured.
• CF03 = 1 and no digital input or digital output configurated as motocondensing unit
ACF5
Circuito n°2 not configured but at least one of its resources are present (relay: solenoid pump-
down, heaters, inversion valve, fan condensing ON - OFF, recovery, auxilairy)
