Product Expert Thermostats

The Honeywell Round Modulation is a digital room thermostat that's easy to control. Thanks to the rotating ring, changing the temperature by a degree or two is a piece of cake. The thermostat features a large, illuminated screen, so you'll also be able to check the temperature in the dark, without needing your reading glasses. Please note that this thermostat is only compatible with modulating boilers that support OpenTherm. If you're not sure that your boiler is compatible, pick the Honeywell Round On/Off thermostat. You can connect this thermostat to the wiring for your current thermostat.

Note: this thermostat is only suitable for modulating boilers that support an OpenTherm protocol.
