Hi, A couple of weeks ago our Stelrad group ideal mexico super rs40/60 stopped working (was no rush to fix as we've an immersion heater and electric shower). The controller is a Danfoss 102E5 with no room themostat. The boiler wouldn't turn on when on the timer, press 1 hour+ or the advance buttons, you couldn't even switch it to on. I was hoping it was the controller and I could just swap it over. But today as I walked past it I noticed that the time display on the controller had gone (must have been on battery for last two weeks) I've checked the fuse in the switch to the side of the controller and changed it for a known good one but still no joy.
Anyone with any suggestions/ideas..
Many Thanks Cris.
