Genuine Waterford Jumo Limit stat to be used with the Donard/Superstar range cookers
- The thermostat uses a sensor to monitor the temperature of your home, and consequently, it keeps an eye on what your boiler is up to.
- If your room thermostat senses that your home has reached its target temperature, it will switch the central heating off.
- Once the temperature drops, it’ll fire up the boiler again.
