Hi,

My thermostat is communicating with the wall unit, but it's not turning the boiler on. All the lights work and it clicks when I turn the temperature dial. I've successfully reset the thermostat to communicate with the wall unit but it still won't turn the heating on. The boiler is heating the water. It was working fine this morning. Please help,it's minus 1℃ outside and I'm freezing 😭

Same problem as below, multiple resets and relearns. Two hours and nothing. About to throw in the towel when I hit it reasonably hard on the front of the case…Bingo!

I have a Siemens RDH10RF thermostat and the receiver unit is not causing the heating to come on. I have changed the batteries and the heating still not coming on. Can you help?

I just tested our system and the sender (thermostat) wasn't talking to the receiver (wall unit bit). I did a reset several times, didn't work.
Finally realised the system had been turned off (on the clock) for the summer. I clicked the little slider within the clock onto the ON position and bob's your auntie: heat :)

Thanks so much for your answer - and it was free and took less than 30 secs to put right!!! The weather's warmer today so don't even need the heating now!!! Could have done with it last night! Thanks again!

Thanks John - it worked for me too. Can't understand why the information manual on Siemens web site doesn't show this crucial information!

press set on the wired in portion then remove the covers on the back of the thermostat. under these two covers you will see two buttons test and learn. press learn this will lock the two units together.press test this will turn the boiler on press test again this will turn the boiler off
