ESi ESRTP4RFW Wireless Programmable Room Thermostat.

The ESRTP4RF+ Is Replaced By The ESRTP4RFW which can be upgraded to a smart control with the addition of our ESWIFIHUB (sold separately)

ESRTP4RFW is a 7 day, 5/2 or 24-hour wireless programmable room thermostat. This removes the need for any fixed wiring between the thermostat and boiler reducing the installation time and eliminates the chance of damaging the aesthetics of the property, with no redecorating or making goods required afterward.

It also comes pre-paired and has two-way RF communication at 868MHz radio frequency band to ensure a more accurate, stronger, and quicker response compared to older styles and allows for a signal strength indicator.
