Brick Core Charge Control - 3100/4100/5100 Series

The amount of heat stored in the brick core of the Comfort Plus system is regulated automatically in relation to outdoor temperature and the heating requirements. The outdoor temperature sensor, supplied with the system, monitors outdoor temperature and provides this information to the Comfort Plus. As the outdoor temperature decreases, heating requirements increase and the system stores more heat accordingly.
