Thanks a lot Si,
It definitely was the power outage, probably due to all this snow. I wish there was some kind of emergency bypass in the boiler for heating in case if something like this happens.
An engineer is coming today to replace it.

Hi,
We are having the same problem here after a power outage. Could you let us know how did you solve this problem? Is there any way to reset the transmitter or you had to buy a new one?
