8 Faults and malfunctions
Possible fault rectification
Overtemperature in the heat pump outdoor unit
▪ Inverter circuit board in the heat pump outdoor
unit defective.
▪ Temperature sensor on inverter circuit board de-
fective, plug connection X111A not correct.
▪ Check, eliminate cause, replace.
▪ If necessary, contact a service technician.
▪ Contact a service technician.
Refrigerant loss.
▪ Refrigerant quantity too low. See fault code
E9015 / E4.
▪ Blockage or leak in refrigerant line.
▪ Check, eliminate cause, top up refrigerant.
Mains voltage outside the permissible range
▪ Sporadic fault shortly after a power failure.
▪ No fault elimination necessary.
▪ Inverter circuit board in the heat pump outdoor
unit defective.
▪ Check, replace.
▪ If necessary, contact a service technician.
Communication between the heat pump outdoor
unit and heat pump indoor unit lost.
▪ Wiring or connections, poor contact.
▪ No heat pump outdoor unit connected.
▪ Printed circuit board A1P defective.
▪ Main circuit board in the heat pump outdoor unit
defective.
▪ Check, replace.
Communication between the A1P printed circuit
board and RoCon BM2C lost.
▪ See fault code E200.
Communication between the main circuit board and
inverter circuit board in the heat pump outdoor unit
lost.
▪ Main circuit board in the heat pump outdoor unit
defective.
▪ Inverter circuit board in the heat pump outdoor
unit defective.
▪ Wiring, poor contact.
▪ Check, eliminate cause, replace.
Configuration of the A1P printed circuit board does
not match the heat pump outdoor unit
▪ Replace A1P printed circuit board.
▪ If necessary, contact a service technician.
WW heating > 6 hours
▪ Check the heating element.
▪ Check that the power supply meets the regula-
tions. Check for frequency fluctuations.
▪ Check the fuses on the printed circuit boards.
▪ Check WW consumption (poss. too high).
▪ Check the building's WW tap.
▪ Confirm that the software and EEPROM on the
hydro printed circuit board match.
