Compensating boiler control

Compensating boiler control may also be known as weather compensation, and refers to a boiler control system that includes an external sensor allowing it to compensate for external temperatures to improve efficiency. Compensating boiler controls can automatically adjust the boiler output based on the outside temperature to help maintain consistent indoor temperatures and improve efficiency. The phrase may be used alongside Time and Temperature Zone Control (TTZZ) indicating a greater level or area and time control for heating systems, often with weather compensation or compensation control as part of this.

An external sensor sends temperature data to the boiler, which then increases its flow temperature in colder weather and decreases it in warmer weather, saving energy and reducing emissions. Such systems are mandatory for combi boilers in the UK and many other heating systems due to their reduction in energy use and thus potential carbon emissions.

With the onset of the Internet of Things (IoT) and smart technology many of these systems can now be wifi controlled, meaning they can be controlled and monitored remotely from a smart phone or laptop.
