Hello,

We can not see anything in the photo. Does the circulator display show consumption or flow?

Hello

In fact no matter what we see in the photo I just want to tell you that passion remains on the position II
Circulator displays nothing else.
Normally I could change my program as I see fit
But I press the button and it's still on position II
Corresponds to a circulator programming for a heating I would like to change programming to go for heating to a twin-tube
