10 110 High force gas temperature This warning appears when the force gas temperature (SGP probe) exce-
eds the threshold set in the parameter. The pre-alarm condition is remo-
ved with the factory-set temperature (default 125°C).
11 111 No compressor delivery pressure
transducer
This warning appears when the compressor delivery transducer is
not detected and the machine is set in heat pump mode, or the pre-
sence of the DCP is set.
12 112 High pressure This warning appears when the transducer detects a delivery pres-
sure greater than the set threshold (default: 40 bar).
The pre-alarm condition is removed with the factory-set pressure
(default: 38 bar).
13 113 No defrosting probe This warning appears when the defrosting probe is absent and the
machine is set in heat pump mode.
14 114 No compressor suction pressure
transducer
This warning appears when the compressor suction transducer is
absent and the machine is set in heat pump mode.
15 115 Low pressure This warning appears when the compressor delivery transducer
detects a suction pressure lower than the factory-set threshold in
cool mode (default: 4 bar), or in heat mode (default : 2 bar). The pre-
alarm condition is removed when the suction pressure exceeds the
envisaged intervention threshold (default equal to 2 bar). The low
pressure alarm is suspended in heat mode for 3 seconds from when
the compressor is switched on; it is permanently suspended during
cycle reverse.
16 - Low output Whenever the machine is powered, the control checks the behaviour
of the compressor once only, via the output control procedure. This
control can be deactivated by means of the dip-switch.
17 117 Pump thermomagnetic switch This warning appears if the contact of the thermomagnetic switch
protecting the pump is opened. MTP. This code is displayed only if the
card is used as a replacement for cards with SW up to version 3.6.
18 118 High pressure capacity control This warning appears whenever there is a capacity control due to the
set threshold being reached. The machine goes into lockout when
the maximum number of capacity controls allowed (default 5) is exce-
eded. With the inverter machine, it also indicates a capacity control
due to a high compression ratio.
19 119
Low pressure capacity control
This warning appears whenever there is a low pressure capacity
control. The machine goes into lockout when the maximum number
of capacity controls allowed (default 5) is exceeded.
20 120 Discharge temperature
capacity control
This warning appears whenever there is a discharge temperature
capacity control. The machine goes into lockout when the maximum
number of capacity controls allowed (default 5) is exceeded.
21 121 Bemf error (chiller inverter) -
error in the detection of the back
emf
This error is given by the inverter control card and is linked to com-
pressor pickup current problems.
22 122 Internal communication error The inverter control card has internal communication problems.
23 123 Overcurrent Excessive current absorption by the compressor.
24 124 No charge The compressor does not absorb enough current and may operate
empty.
25 125 Incorrect voltage The inverter control card indicates an incorrect BUS voltage.
26 126 Start-up error The inverter control card indicates the incorrect start-up of the
PMSM motor.
27 127 IPM protection error Error on the IGBT.
28 128 EEPROM error Eeprom error on the inverter control card.
29 129 Compressor stalling
30 130 No communication The inverter control card does not respond; it may not be powered,
or the serial cable may be disconnected, or the A and B signals may
be inverted.
31 131 PFC module Error in the PFC inverter module.
