Hello everyone,
We have a timer switch for the heating circulation pump, see the picture.
But no matter how I set it, the circulation never works as it should. I just don’t understand it!
There are three modes you can set: permanently on, permanently off, or according to the schedule (middle setting).
I set it so that, for example, it should circulate tomorrow between around 6 and 9:00 AM. But it doesn’t. Of course, I also set the current time correctly according to the small arrow. I’ve tried everything.
What am I doing wrong?
Our heating system also has an option to control the circulation, see the other photo.
According to the heating installer, this won’t work if the manual timer is activated.
It really never works as I set it—for example, at 6:30 AM, freezing cold water for 1 minute.
FRUSTRATION!
Do you have any idea what this could be? Thanks a lot

Yes, that is correct. It appears to be an Ecocirc Pro, which is available in various models, including ones with a mechanical timer. However, this timer can be deactivated (as in this case), and the pump is then controlled solely by the heating system.

The electrical connection is definitely correct, but are there any other settings on the heating system that could prevent circulation or, conversely, start it independently from the electronic schedule?

I find this installation quite unusual.
Who would install a manual timer or a circulation pump with a manual timer on a heating system that can control the circulation digitally by itself?
Is this a Novelan heat pump?
My control system looks similar.
Of course, it’s possible that the circulation pump isn’t working at all.
That often happens if these units don’t run for a longer period – they tend to get clogged with scale.
Alternatively, you can check how long the circulation times are set in the heating controller.
For example, mine is set so that the pump runs for 5 minutes and then pauses for 30 minutes.
Maybe it’s incorrectly configured.
But generally, I would probably look for a different installer...

Even a state-of-the-art pump can still have a mechanical timer attached. Most likely, this option was simply more cost-effective.

This happens quite often when the pumps haven’t been running for a long time – they tend to get clogged with limescale.

The heating technician was here this morning; he said we should keep an eye on it and that the circulation pump might be broken. He made a few adjustments but didn’t explain much. My questions weren’t answered… really frustrating.
I suspect the pump really is broken. Let’s wait and see.
