My building is under heating, especially when it’s cold outside.

On the display the boiler control will show the outdoor temperature reading in the View menu. In some cases, the outdoor temperature is reading much warmer than the actual ambient outdoor air temperature. This results in the heating system using cooler water temperatures to heat the building.

The location and installation of the outdoor air sensor on the outside of the building is very important. The outdoor sensor should be installed on a north-facing wall and away from any heat sources such as direct sunlight, vents, doors, and windows. Warm air from the building can travel from inside the building along the hole in the wall where the sensor wire is pulled. Ensure this hole is sealed using silicone or spray foam.
