"Central heating didn't work. The boiler was working so the most obvious problem related to the room thermostat. This is a very basic model having basic features. The old thermostat was the same make with similar settings. Fitting the replacement was so simple. We now have a nice warm house."
"Quick to install, works well as a replacement for Potterton PRT 100 stat. Same footprint and connection schedule. Accurate temperature calibration and low hysteresis so maintains a good constant heat. Good value."
"Well, it is basic device so you cannot expect miracles. Easy to install and does the job. I have used it for gravity fed heating system but it is designed to work with Combi Boiler, and manual is designed to replace thermostats connected to combi boiler.
If you know what you are doing, you can use it with any system it is for you, but if you are basic DIYer and looking to replace like-for-like for gravity fed system, then find some other option"
