- A4Error codeTemperature sensor, in- verter (IGBT module) faul- ty
- A5Error codeTemperature sensor pow- er factor correction filter faulty
- A9Error codeCurrent phase L1 of com- pressor too high
- and12Error codeHeat pump
- B0Error codeFan communication fault
- B1Error codeFan motor overheats
- B2Error codeFan motor speed monitor faulty
- B3Error codeFan motor blocked
- B4Error codeFan motor supply voltage too low
- B5Error codeMotor of fan 2 (bottom) blocked
- B9Error codeSecondary pump blocked
- C9Error code■ One of the following events has occurred: - High pressure limit was exceeded 3 times within 60 min (Vitocal 100-S/111-S only). - Low pressure limit was undershot twice within 40 min (Vitocal 100-S/111-S only). - Flow switch has responded 9 times. - Compressor was switched off by the refrigerant cir- cuit controller 9 times. - Defrosting process was terminated. Note The event counter is reset as soon as the compressor has been operational continuously once for "Opti- mum runtime compressor 500A". ■ Safety chain is interrupted for more than 24 h. ■ Event that leads to the compressor being switched off is active for more than 24 h. ■ Primary/secondary circuit flow and return temperature sensors are simultaneously faulty for more than 24 h
- HC1Error codeHeating circuit pump heating circuit A1/HC1
- HC2Error codeHeating circuit pump heating circuit M2/HC2
- HC3Error codeHeating circuit pump heating circuit M3/HC3
- hin24Error code■ Instantaneous heating water heater faulty ■ High limit safety cut-out has responded. ■ No temperature rise within 24 h
- HP1Error code
- HP2Error codeCompressor 2 with 2-stage refrigerant circuit ("Heat pump 2")
- L1Error codeElectrical power measured by the energy meter in kW for each phase: Positive value: Electrical power is fed into the power grid. Negative value: Electrical power is drawn from the power grid. Note The polarity can be changed by a heat pump installer certified by Viessmann
- M2Error codeShort circuit, flow temperature sensor, heating circuit with mixer M2/HC2
- M3Error codeShort circuit, flow temperature sensor, heating circuit with mixer M3/HC3
