F Overview of fault codes
Code Meaning Cause
F.022 Water pressure too low Insufficient water in the heating system
F.037 Fan fault
–
Obstruction in the product's air pipe
–
Fan motor not connected or defective
–
The connection between the main PCB and the fan PCB is dam-
aged or broken
F.042 Fault: Coding resistor
–
The product's coding resistor is missing or is defective
–
Coding resistor value outside the permissible range
–
X25 plug not connected or was connected incorrectly
F.073 Fault: Water pressure sensor Line to water pressure sensor is broken or has a short circuit
F.086 Surface-mounted thermostat opened
–
Underfloor heating temperature too high
–
Heating circuit flow rate quantity too low
–
Underfloor heating circuit is closed
F.103 Fault: Spare part detection
–
The parameter Max. duration power supply cut-off has been
poorly set (see "Heat pump setting parameters" in the appendix).
–
The main PCB that is fitted as a spare part or the frequency con-
verter does not match the product.
F.514 Temp. sensor fault: Compressor inlet
Sensor is defective or incorrectly connected to the main PCB
F.517 Temp. sensor fault: Compressor outlet
F.519 Sensor fault: Return temperature
F.520 Sensor fault: Flow temperature
F.523 Sensor fault: VF1 Line to temperature sensor VF1 is broken or has a short circuit
F.526
Sensor fault: Temp. environment circuit EEV
1)
Sensor is defective or incorrectly connected to the main PCB
1) Sensor on the evaporator
2) Sensor on the condenser
