## Customer Reviews

### ⭐⭐⭐⭐⭐ Value for money, accurate control.
*by  on Reviewed in the United Kingdom 5 January 2026*

easy to install on two wire system, displays set point and current temperature with simple rotary temperature control. Has much closer temperature control with smaller dead band and less overshoot than previous controller. has shorter heating and rest intervals to ensure temperature stays close to the set point. Temperature checked against a glass thermometer and is spot on.;

### ⭐⭐⭐⭐⭐ Excellent product and Service
*by  on Reviewed in the United Kingdom 14 December 2025*

Excellent.

### ⭐⭐⭐⭐ Excellent room thermostat! Easy to use!
*by  on Reviewed in the United Kingdom 27 December 2025*

It can be a little confusing if you don't realise that there needs to be at least 1 degree difference between the current room temperature and the selected setting before the boiler will be instructed to turn on the heating. Otherwise it works really well. The numbers are big enough to see and changing the temperature setting in 0.5 degree steps, using the big rotary dial is simple.
