ACF7
If the pump down function is enabled but in at least one circuit
The relevant solenoid valve relay is not configured
Pump down pressure switch or circuit evaporating pressure transducer
are not configured and the pump down is enabled also at start or not
even the low pressure pressure switch is configured
If at least one pump-down solenoid valve has been configured but there is no
exact correspondence with the circuits
ACF8
One or more compressors have been configured using parameters
CF05 and CF08 but the relevant main relays are not configured
Intermittent valve relay not configured when enabled by ON/OFF times
(CO10/CO11)
!
0 or vice versa.
No partialisation and no gas by-pass when by-pass time (CO15) is
!
0
No second winding or star/delta relays configured and CO12
!
0 or
vice-versa (relays configured but CO12=0)
No full match between relays configured and unloaders defined on
parameters CF09 – CF12.

ACF10
No temperature control probe (in cooling ST09, in pump mode when ST10
enabled) is configured correctly (it does not exist or is not NTC)
ACF11
Heat recovery enabled but
•
Not all resources needed are defined in a circuit (condensing probe,
heat recovery request d.i. heat recovery relay)
•
Free cooling or domestic hot water are enabled
ACF12
compressors with unloaders/modulation:
•
at least 2 analogue outputs are configured as power modulation of the
same digital scroll compressor
•
one or more unloaders relays are defined but the compressor main
relay is not defined
•
modulating compressors enabled in condensing units
ACF13
Compressors with different weight:
•
compressors with inverter
•
at least 1 of the compressors defined has a weight 0
•
the temperature control is not at neutral zone
