It is a T3R thermostat which is flashing the year and will not respond to any of the control buttons

Hello, thank you for using Howly.
Have you tried something by yourself with the T3R thermostat?

Could you please tell me if you started having this issue recently or was it present after you first set up the device?

Set up last April when I had a new boiler into

I see, and when did the thermostat stopped responding?

Stalled. Worked fine until this morning

Got it, have you checked if the device needs the batteries to be replaced?

Customer Replay

Sorted. Thankyou

Good to know! Was the issue with the batteries, *****?

Customer Replay

Yes but initially couldn't get cover off

Oh, I see! Does everything work properly now?
