Is there a way to control the pre-hreater?

[opt12]

Hello everebody!
I'm wondering, whether there is a way to programatically control the pre-heater of the Comfo-Air unit.

I'd like to et some more control over the pre-heating device to ru it primarily on solar power and give some allowance for a certain amount of icing (clogging) during nighttimes.

Do you know whether there is some API call to activate or deactivate the pre-heater?

Did you find out about the API solely by reverse engineering or is there any documentation available from Zehnder?

Cheers,
Felix

Additional Information:
The pre-heater is used to avoid icing on the inlet of the heat exchanger and hence mainntain the airflow even in cold conditions. This is especially necessary in houses with some chimney installed as icing on the inlet would cause some underpressure (more air gets out than in) within the house and could cause smoke to be soaked. So deactivating the pre-heater must be avoided in cases where there is a danger of soaking in smoke gases. However if this is not possible, it shoud be OK, to monitor the clogging and do some "manual" de-icing at appropriate times.
