C-Stat 11-B and 17-B

Battery powered programmable room thermostat

Programmable room thermostats are widely recognised as one of the best ways in which to control central heating. Our

C-Stat programmable room thermostats have a large display and intuitive user interface, making them easy to set up and use. C-Stat uses a sophisticated time proportional integral

(TPI) algorithm for accurate temperature control and energy efficiency. Being battery powered, these models are suitable for replacing most existing room thermostats.

C-Stat is ideal for combi boilers, extra heating zones or upgrading older inefficient room thermostats.
