Wired programmable room thermostat

The ESRTP4 is an easy to install-and-use 7 day, 5/2 or 24hr programmable room thermostat which offers up to six time and temperature changes each day with different programmes for weekdays and weekends. The ESRTP4 has all the energy savings features such as TPI, Delayed Start and Optimum Stop and the all-important Landlord Service Interval.

Battery powered for ease of installation, the ESRTP4 has a large, easy-to-read blue backlit LCD display. It is easy to programme and operate because of the built-in programme options that the user can easily change to suit individual heating requirements.
