5 Series Digital Room Thermostat

The ESRTD5 is a simple electronic room thermostat designed for accurate temperature control with an LCD to display current room temperature, set temperature and flame indicator when the system is calling for heat making it an ideal upgrade for any heating system.  Users can also select TPI technology for further energy savings.


The simple click on/off backplate is designed to be fully interchangeable throughout the entire 5 Series range and, with just a 5 volt connection, can be changed over safely by the homeowner without disconnecting the power or re-wiring.  The new unit will simply click on to the existing backplate and be ready to use – it really is as simple as that.  This gives the homeowner full control and flexibility to interchange between any of the 5 Series Room Thermostats with no need for an electrician.


Three wire models with the additional energy saving feature of Delayed Start (ESRTD5D) are also available.


Wireless models are available using 868Mhz 2 way technology for accurate and responsive communication and an easy retrofit solution (ESRTD5RF).
