My room stat can be showing a good few degrees below it's 'on' setting temp, so I would expect it's receiver to remain switched on ....... so just awaiting a command from the boiler. Any reason why it (the receiver) still switches in and out randomly????? This is without any room temp change and prior to anything being turned on. The whole installation is a little under two years old and generally works fine but sometimes I come home and switch the boiler on but it does not come on straight away as the receiver is switched off (it has a green indicator light on it when it is on) It can be a few minutes (maybe slightly longer) before it switches the boiler on. I am talking strictly central heating control. It is Honeywell kit Y9240S1005 although the receiver is a bit different to the one showing in my old screwfix catalogue. (I will double check this item) It is this one. https://www.screwfix.com/p/honeywel...ss-digital-wireless-room-thermostat-eco/84904 Thank you.
