The principle of weather compensation is to vary the output of the heating system in relation to the outside temperature.
This is typically achieved by mixing hot water from a primary loop into the cooler secondary loop (the water passing through the radiators). This is varied by using a motorized valve, driven by the compensation control. An outside sensor is required to monitor
outside temperatures. Siting of this sensor is crucial to effective control
THERMSAVER Load Compensation
The outside temperature changes have an impact on the system and its control, when it gets colder the system controls react by allowing more heat into the building to maintain the room temperatures and
vice versa. When the system responds to these changes there is a measurable effect on the water temperature when it returns to the boiler. It is at this point that Thermsaver monitors these changes and is
able to adjust the boilers output - so Thermsaver compensates for these weather changes in a similar way to the traditional weather compensator.
Thermsaver is compatible with existing weather compensation systems. If no weather compensation exists Thermsaver provides a compensation action via monitoring load which is affected by all external and internal conditions.
