ESI Wireless Programmable Room Thermostat ESRTP4RF+

The ESRTP4RF+ 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.
