Thank you Mark.

So helpful, thank you 😊

Hi There, I agree, it would be good to have a permanent display showing the room temp. Is there another product that you could recommend that has that function? My boiler is a standad type, not a combi.....Many thanks

Could you make a video explaining the menu when you press and hold the button for several seconds?

Hello! 👋🏽

[@LewieLeway]

I have a Honeywell home t3r. The problem is, I set it to , say, 19.5 and it switches off at 18-18.5. Any idea why?

[@ponderer467]

How does a thermostat work with a programmer. I have that same Drayton programmer and it always overrides the thermostat

[@paulsmith2931]

Surely given the age of that boiler it should really have a programmable room thermostat to meet current regs.

My dt4-1 hard wired thermostat has a blue frost sign on it that I cannot get rid of?? by scrolling through??

[@chatlow]

anyone else's DT4 click very loudly and quite often? I have a heat only boiler system with thermal cylinder store. Set the programmer water and heating to on for most of the day and can hear the stat clicking on and off numerous times

I have just installed a DT4 and it seems to be very sensitive, switching on and off all the time. Very annoying.
