Hey All,
Trying to find out if this is something I can fix or just needs replacing.
I had a house renovation about 8 years ago and one of the things they did was add in a Horstmann T50 RF thermostat up to my boiler.
It's worked fine up till a few weeks ago where it doesn't seem to be turning on the heating consistently. The signal isn't getting through.
I've had to walk the thermostat upstairs till it was nearly touching the receiver box next to the boiler and even then it sometimes doesn't pick up a signal. Most times if it does, it only stays on for a minute or so before turning off again.
Replaced the batteries to no avail so it's not short on power. Is this something that I can replace just the thermostat or is the receiver at fault? Do I just scrap the lot and buy a new one? If so, is that easy for a novice to wire in? I can wire up a plug fair enough and from what I've seen online, the receiver box is not a lot different so long as I keep the same wires going to the same ports?
Any help would be appreciated, thanks!
