Works nicely easy to program

The DEVIreg 535 Programmable Thermostat is a really great thermostat and works very effectively.

Excellent service. Prompt delivery, perfect for our needs as our underfloor heating thermostat in the bathroom had stopped working and the tiles were cold on these chilly mornings

Thank you for taking the time to review our service as excellent, we appreciate the great feedback.

Nice unit, good price, prompt delivery. It was installed and working the next day, replacing an old DEVIreg unit which had died!

I ordered the 535 and it was delivered within a couple of days.

Thank you for your review of our prompt free next-day delivery, that's really great to hear.
