![]() Now looked at pictures and yes same thermostat as I had, and it seems same fault, also known as HRFS1 there are 5 connections on the base, the NC is not used and some times there is a link between L and Com so could be 3 core and earth or 4 core and earth and the earth is not used it just has to be there. 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?Īny help would be appreciated, thanks!

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. It's worked fine up till a few weeks ago where it doesn't seem to be turning on the heating consistently. 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. ![]() ![]() ![]() Trying to find out if this is something I can fix or just needs replacing. ![]()
