Hi @sathya, there are certainly configurable parameters in channels 1 and 3 - decalcification, vacancy time, night temperature, open window temperature … Things of this kind; always the person I spoke with some time ago, showed me the configuration page of the Homematic devices and these parameters, such as channels 1 and 3, were correctly displayed; I think it’s a bug on the MAX page…
– edit
this is reference to the thread
– second edit
the channel that should be viewed / edited is number 1 instead of 2 which is empty; that’s the bug …
Cheers
Michele
