Horstmann HRFS1 Programmable Room Thermostat is rated 4.1 out of 5 by 100.
Rated 1 out of 5 by from Absolute rubbish Have had this a little over a year. It no longer turns our brand new boiler on when it is supposed to, and also does not turn it off, despite having a plumber set it up and it working initially. Seems like it has been discontinued by Horstmann but still being sold by Screwfix...? Don't waste your money.

Rated 5 out of 5 by from Easy to fit would recommended this as easy to fit and just as easy to set up and use, very happy with it.

Rated 2 out of 5 by from Very unreliable I fitted this in a 1 bedroom flat to replace a Flomaster. It worked 70% of the time which is just not good enough especially as it was only 6 meters from the receiver. I tried changing the channel and moving it around but no improvement. Thinking it was a defective unit I replaced it with another but no improvement. I then tried it in another house. It was equally unreliable. There were two solid brick walls to cope with but the Flomaster had worked fine. I ended up using a Honeywell unit at a much higher cost but it works every time in any location. Seems it's worth paying the extra.

Rated 3 out of 5 by from COULD BE BETTER I bought the thermostat to control a combi oil boiler which is in a cupboard with the sensor about 6M away. The walls of the cupboard are just plasterboard but the thermostat was incapable of operating through the plasterboard. I thought it was faulty so returned it for a replacement. That was just the same. The RF signal must be very weak as my wifi (which operates on similar frequencies) penetrates solid walls and plasterboard with no problems. I finally installed it outside the cupboard where it has just an air path to the sensor 5M away. Disappointingly, if the receiver misses the signal from the transmitter there's no checking procedure to re-transmit the signal. I guess if you want a better device it will cost considerably more.

Rated 5 out of 5 by from Great but why no wall bracket? Super wireless thermostat but my only gripe is that I would like to keep the sensor unit mobile and a wall clip or bracket would be extreamly useful as it would allow you to mount the sensor in the ideal thermostat position and still allow you to move it as required. It comes with a folding base where you have to find a high shelf to site it or screw it permanently to the wall.
