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

Does the timer switch still work at all?

The device (and our heating system) is 1.5 years old, so I really hope it still functions properly.

"Faith and hope belong in church."
or
"Believing/ hoping is not the same as knowing."

Based on the traditional construction method, I would have guessed it’s actually older than 1.5 years (1.5 years) anyway. But even after 1.5 years (1.5 years), things can be faulty – it was just a note 🙂
Not saying it’s the same situation here like with the person who had "the empty tank."

Based on the traditional construction method, I would have guessed it is older than 1.5 years (5 feet). But even after 1.5 years (5 feet), things can be faulty – it was just a remark 🙂
Nothing to suggest this is similar to the case with "the empty tank."
I wrote to our heating engineer to have him take a look at it.

What exactly doesn’t it do?
Circulate at the wrong time? Not circulate at all?
