Hi. I'm hoping for some advice. We have a very ancient thermostat for our radiators in a very old building.
This morning there was no heat and the display was blank, so I've changed the batteries and reset, but I can't change the time to allow the program buttons to work.
After the reset, I get 3 displays in succession. The first says 03:00 Sr, then it quickly moves to 11:00:00 (but it won't let me change this, even if I press + or the up arrow really quickly). It moves on again very quickly to the 3rd display which just has a flashing colon, like the one in the middle of a time display but doesn't show any numbers and won't allow me to add numbers by pressing any of the buttons.
I have managed to change the temperature so the heating has come on but I won't be able to program until I can set the time. Watching the YouTube video Getting Smart with Dad didn't help and ringing DanFoss customer service didn't either. Are there any experts out there please? Thank you
