[ENHANCEMENT]: Softstart and Night reduction #147

Closed mabek closed 6 months ago

mabek commented 6 months ago

Really appreciate your effort so far, great work! One combination I couldn't get to work properly in my case is Softstart and Night reduction.

Whenever the target temperature is lowered by night reduction and soft start lowers it even further, I am getting into situations where the heatpump shuts down very quickly.

Describe the solution you'd like Option 1: Option to set a maximum correction amount : Lets say soft start wants to do -2 and night reduction is -2 but there is a maximum correction amount of -3 the result is -3.

Option 2: Option to have soft start only activated whenever night reduction is turned off.

Hi! 😄

Under SETTINGS, there is an option to set a hard lower limit for the setpoint.

Heat water temperature limits

Would this work for you? There is a fixed limit where a heat pump can work well. Each situation specific ofcourse

I tried that option already, but according to WAR the temperatures would be to different when its cold or warmer to find a decent lower end. Did not help much.

Hi,

In the scheduler, you can already 'toggle a function' Turn softstart off at the time night reduction is turned on and vice versa. This way you need 2 schedules to get what you want. Is this good enough?

Great idea, didnt think of this one, thank you! 😄

Took me a while as well :)

If this is solved, you can close the issue.
