Have a Worcester Bosch Combi Boiler controlled by a Honeywell CM921 wireless thermostat.
The button on the thermostat seems to have no effect when pressed so I'm guessing I need a new thermostat?
The CM921 is no longer made and a T3R looks a viable replacement but it's £75 ish.
Can anyone recommend a cheaper one that will do the same thing, or a way to get the button on the CM921 to work again, cheers
