Introduction
The RET2001OT room thermostat varies the heat output of an OpenTherm compatible condensing boiler by modulating the boiler flame. This improves boiler efficiency and maintains economical condensing mode whenever possible.
Daily use is as easy as setting the thermostat to the required temperature, the advanced electronics and software within the thermostat establishes two-way communication with the boiler to ensure optimal operation.
What is a room thermostat?
A room thermostat controls the heating in your home by keeping it at the temperature you have set. Room thermostats switch off the heat when the temperature reaches a set point, and switch it on when it falls below. The heating will not come on if the room temperature is above the room thermostat set temperature.
Remember that turning the thermostat up will not heat the room any faster. The higher the thermostat setting the more gas you will use.
