[ENHANCEMENT]: Reset RTC calculated shift to 0 when unit switches on.

[B-Lourens]

Is your feature request related to a problem or use case? Please describe. When using 'Nachtverlaging' and 'RTC automation' and 'Action: turn power on/off' there is a chance of unwanted behaviour. When the panasonic is OFF, the RTC shifts are being calculated, but they're not sent to the unit. Example: The RTC is set to -3 and at some point the 'nachtverlaging' starts, depending on settings and other circumstances like current temperature, the 'Trigger action above dT' can be executed, and the unit can be switched off. While the room temperature drops, the a new RTC shift will be calculated, but the unit remains at the -3. When the 'Trigger action below dT' is executed, it will turn on the unit, with the last know shift; -3. This wil cause the room temperature to decrease further until the next 'Too cold' configured trigger is hit and a new shift is calculated.

Describe the solution you'd like When the 'Revert action below dT' trigger is executed, the temperature is below the configured setpoint. Thus I want the unit to start heating asap, using the default WAR calculated water temperature. To accomplish this, I want to reset the shift to 0 when the unit unit switches on (and have the RTC pick it up from there).

Describe alternatives you've considered On the schedule page: Make a new action: "set shift" where the user can input -3 to +3. Make a new condition: "if unit is switched on".

Or make it an switch on the RTC screen, add/combine it to/with the 'Action: Turn off/on power'
