VCW376 setting desired temperature for the day

[vinne81]

Hi,

I have a Vaillant VCW376 with thermostat. This thermostat has a physical dial. You can control the desired temperature for the day. Only if you press the button it saves this value for the future.

I have ebusd completely operational. These are the permanent registers, setting them changes temp for today and also for the future:

ebusd/370/Hc1DayTemp 21.5
ebusd/370/Hc1NightTemp 14.5

But I want to change the desired temperature for today only, for the current "timeslot". I also have these values:

ebusd/370/ActualHc1RoomTempDesired 21.5
ebusd/370/DisplayedHc1RoomTempDesired 21.5

Setting these does nothing. Probably normal, they are called "Actual" and "Displayed". But there is no other 370 that would match anything so I can set these values I think?

So my question: is it just impossible to set a temperature for today only using ebusd? Anybody done this?

Thank you
Vincent
