On commissioning (or the case of error 10), the electrical
back-up heaters are liable to start up even if the outdoor
temperature at the time is above the heaters' trigger
temperature.
The regulating system uses an average initial outdoor
temperature of 0°C and requires some time to update
this temperature.
To avoid this situation, the sensor must be connected
correctly. Re-initialise parameter 8703 (commissioning
level, consumer diagnostic menu).
