• The number of compressor of the 2 circuits (CF04 + CF05) is:
√ > 4
√ > 4 with no direct compressor start-up (CO10 ≠ 0) or the number of steps
is > 0 (CF06),
√ > 2 and the intermittent valve is configurated
• Pump-down function but at least in one circuit:
√ The pump-down solenoid relay is not present
√ No pump-down pressure switch or evaporating probe when
 the pump-down is enabled with unit in start
Or
 No low pressure switch configurated.
• The compressor configuration with CF04 and CF05 but not the relay
outputs:
√ Main relay of the compressor
√ Intermittent valve when enabled with the ON / OFF time (CO08 / CO09
> 0)
√ When the by-pass time >0 and there is no partialization or by-pass
valve configured
√ Coil 2 of part-winding start up
√ Requested step valve for screw compressor are configurated
• One relay is configured as:
√ Compressor not selected in CF04 or CF05
√ Intermittent valve configured but CO08 =0 and CO09 =0
√ By-pass gas valve configured but by-pass time = 0
√ Coil 2 of part winding start up configured but direct start up selected
• Wrong configuration of the capacity step valve
ACF7
Evaporator pump
√ Enabled (CO16 >0) but the relay is not configured
√ Not enabled (CO16>0) but the relay is configured
Condenser pump
√ Enabled (CO21 >0) but the relay is not configured
√ Not enabled (CO21 = 0) but the relay is configured
Allarm configuration water pump in antifizee alarm
• if Ar24=1 and Ar25=0
or
• ifAr25=1 and not probe configurated like NTC
• if Ar29=1 and Ar30=0
or
• Ar29=1 and wrong confìguration of the probes
ACF8
• Regulation probe
9 The regulation probe selected by ST09 or ST10 is not properly
configured
9 Compressor rack is configurated with termoregulation like pressure
probe and the pressure probe is not configured
