Hi,
I got a problem with my vitopend.
When unit starts there is red led blinking and display keeps loading (no error code).
There is no problem with heating but i cant control water temperature cos i cant see anything on the display just loading.
Any idea what might be the problem? Ive replaced control unit 3years ago.
Thank you

Make the the display control cable is firmly plugged in. If it is, you may need a new display0

Im not sure if i have to buy new controller or it might be some smaller problem (cable, sensor etc) .
I dont want to spend lots of money on this old unit.

Ah, I haven’t seen that one, you need to get Viessman on the phone0
