This thermostat has been discontinued

The Polypipe PBPRP Programmable Room Thermostat has been discontinued and replaced by the UFHPROGBW Programmable Room Thermostat.

The UFHPROGBW is a two-wire, battery-operated thermostat from a different manufacturer. Please note that it is not compatible with a 10k NTC remote sensor cable, so it may not be suitable for every existing PBPRP installation.

View our Polypipe UFHPROGBW Programmable Room Thermostat product page for further details. The replacement is available to order on request.

If you're unsure whether it will work with your current underfloor heating system, contact our team before ordering.
