I have recently fitted one if these units myself after a receiver problem with old timer. Boiler comes in great timers seems manageable. But since it is the summer months not really using boiler much.
I have noticed now for a while that the display always seems to state it us 20 degrees is there something obvious wrong !any advice would be great.
