2nd heater,3rd heater etc if there is a big gap between setpoint and real temprature.

2nd heater,3rd heater etc if there is a big gap between setpoint and real temprature. So it will do 1st heater usually, but if the diff is high it will also use 2nd heater, if it is a even bigger gap then the 3rd.
I use the activity mode to switch between eco and comfort mode. But the gap is a bit big (17C to 22C) and with just one heater it takes to long. But when it just needs to "keep" the temperature one heater is enough. so if it could use the 2nd heater when the diff is big and not to keep i would not need to manually turn the 2nd heater on and off.

Hello @flippz ,

So it will do 1st heater usually, but if the diff is high it will also use 2nd heater, if it is a even bigger gap then the 3rd.

This is exactly what does the VTherm natively. If possible, it just shift the starts of the heater to avoid having all in // but after the starts , they will acts in //.

Ok I'll test it out...But what i understod was that they are not on at the same time but rather alternate. Will report back :)

[flippz]

As you can see from the attached picture it is not working as i hoped. It keeps alternating between the two heaters. I would like it to use 2nd heater ONLY when temp is far from the setpoint (2-3 degrees)

[jmcollin78]

It should definitively work. Here is how it is supposed to work:

There is something weird in your configuration I guess:

1. the heater 2 starts at 17h25 only ?
2. are you sure they are all in the same VTherm ? Can you give me the attributes of the VTherm accessible in Development Tools / States (in yaml formatted with the <> button).

[flippz]

As far as i can see from you picture it is not what i want. I would never want 2nd heater to be on if the temp is within +/- 1degree of setpoint.
I removed the 2nd heater now (its a noizy fan oven) but i will re add it and send the code to you

OK. I don't understand this. This is too much specific to your case, and I will not do that.

Your configuratin seems good to me.

[flippz]

No worries. I just wanted it to not use that noizy heater if it is not nessacery. I'll just use it manually in stead

There is some feature named "auxiliary heater" in the standard HA thermostat. Maybe you can have a look. I don't exactly what it does but it could be something near what you need.

[flippz]

Thank you 😊 I will take a look at it 👍👍 tir. 12. des. 2023, 20:17 skrev Jean-Marc Collin ***@***.***>:
