Circulation timer on the heater

If you turn on the pump manually, you should hear / feel if it's running. What are you waiting for?

I basically notice that it's not running. I set the time dial and when I go back hours later, the dial is still at the starting point. It doesn't turn at all, even though it definitely should while running. I will wait a bit now and then get back in touch with the heating engineer.

But the pump also has a mode for simple on/off. If you have your hand on it and switch it on, you should be able to feel/hear that the pump itself is running. Completely independent of any controls. Of course, this only works if electrical power comes from the heating control at all.

Then the timer can't be working :D As writes, just turn it on to see if it even runs. Does it have power at all? I'm not sure, Christmas lights were a while ago, but a timer clock ticks quietly when the clock is running, right?

Where does the power for the timer switch come from? I wouldn't be surprised if the power for the timer switch comes from the heat pump. And this, however, is deselected in the menu.

The power definitely comes from the heat pump. I absolutely have to check it again right away, I am on the go.

Exciting!
