The RFTC Series: One Thermostat Family, Built for Every Project

No two projects are ever the same. A hotel room has different needs than a family home. An office retrofit behaves differently than a new installation. And that’s exactly where the RFTC series fits in.

Instead of forcing one solution everywhere, the RFTC range gives you carefully designed thermostats, each built for a specific purpose, yet all sharing the same elegant glass design, wireless flexibility, and smart energy control.

It’s not just about controlling temperature. It’s about creating comfort that feels effortless.
