• not defined (CO21 = 0) but one relay configured
Evaporator / condenser pump configuration alarm due to anti-freeze
•if Ar24=1 and Ar25=0
or
•if Ar25=1 and there are no probes configured as NTC
or
•if Ar29=1 and there are no probes configured as NTC
ACF8 Temperature control probes configuration:
• one temperature control probe (in chiller ST09, in heat pump when ST10 is enabled) is not
correctly configured (does not exist or is not NTC)
• controller enabled with pressure control the associated pressure control probe is not defined
ACF9 Recovery enabled but in one circuit only certain resources are defined (the following are necessary:
condensing probe, recovery request digital input, recovery relay) or no output is defined.
AC10 Compressors with inverter:
• there are at last 2 analogue outputs configured for capacity modulation of the same compressor
• the output is defined but the main relay of the compressor is not defined
• modulating compressor enabled and unit configured as condensing unit
AC11 Capacity controlled compressors
• digital scroll compressors
• at least 1 of the compressors defined has significance 0
• temperature control is not in neutral zone
AC12 (free cooling configuration) if:
• the free cooling output relay is not defined
• the probes for free cooling control are not defined
•if FS21 < FS22
•if FS01=2 and CF97=2
AC13 (domestic hot water configuration) if:
FS01>0 and:
• the out1 output relay is not defined
• domestic hot water temperature probe 1 is not configured
AC14 (relay outputs configuration) if:
a relay is configured with values 75 or 76
