Setting Matrix Fan Control
Just as the Matrix Boiler Controller controls all of the operation and safety functions of the boiler, the Matrix Fan
Controller controls all of the operational functions related to air handling and hot water dispatching. The fan
controller controls the forced air modulation, ventilation, as well as priority of domestic hot water and secondary
heating systems. See Table 13-5 for a description of the fan control settings.
