"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."
