The classic Honeywell Round as a simple electronic on/off thermostat. The turning ring sets the temperature in half-degree steps; the backlit display shows the set temperature. The thermostat is powered by the boiler (24 V on/off control), so there are never any batteries to replace.
Suitable for boilers with a 24 V on/off connection. For modulating control with an OpenTherm boiler, choose a modulating thermostat.
