Danfoss RETB RF + RX1 Room Thermostat
Easy to install, simple to use
Bought this to connect to my old Worcester combi, which had no room stat fitted, just TRVs, as we were always having to switch the heating on and off (and even open windows) to maintain a pleasant temperature in the house.
The receiver was easy to connect, just 3 wires. Can be fitted right next to the boiler, so no damage to decor.
The thermostat/transmitter can be tried in various locations before fixing in place, which is very handy. It is delightfully easy to use, just a single control, plus a 2-digit LCD which indicates the actual room temperature all the time, except whilst adjusting the control when it indicates the target temperature instead. It looks very neat too.
Solidly made, though had to return first pair for under-guarantee replacement when range deteriorated for no apparent reason. Second one is still going strong after 4 years.
