Valmet Kotilämpö B
Why does Vallox Aito Kotilämpö report an error during the defrosting cycle?
If the control panel of Aito Kotilämpö reports an error, check the main settings first.
- Defrosting method: Bypass, Indoor %Rh 0, and Outdoor air °C 20.
- Heating settings: Heating method Electrical resistor (Must never be turned off!) Post-heating None.
- Control settings: °C adjustment method Extract air and Humidity Automatic.
- 1/0 and bus settings: External sensor Setting: Air heating. Relay settings: Air heating.
If the error persists, carry out a heater test as follows: When at least 5 minutes has passed since the error message disappeared, check the supply air temperature (°C) from the temperature display of the At home mode and write it down. Next, test the additional heater. When the test has been on for a couple of minutes, you can exit the test. The supply air temperature should now be higher than previously in the temperature display of the At home mode. If this is not the case, the additional heating resistor or the relay that controls it is faulty. There is no need to carry out a post-heating test; in fact, the test cannot even be carried out, as the ventilation part of Aito Kotilämpö does not have a post-heating resistor.
