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. It incorporates a real time clock and calendar function which automatically changes between BST/GMT time changes. Time and date are factory-set making time setting or adjustment unnecessary.
