Buttons don’t work on my Norma Digital Programmable thermostat,
Temperature on screen not changed, furnace continually heat it is very hot, but temperature on display 19 -C only. Room thermometer shows 26-C
What to do??

I would suggest contacting the installer of the stat, or if you installed it yourself, try contacting the manufacturer. They should be able to help you out.

Hi,
I resolve the issue myself. I disconnected the thermostat and took away batteries for half an hour, then connect it again put the same battery back and reset it.
It is working normally now for the last 10 hours.
May be it will help to somebody...
Thanks,

Thanks for the update.
