Description: The House Control 403 operates an On/Off boiler with indirect Domestic Hot Water. Mixing is performed with
variable speed injection, which supplies an outdoor reset water temperature to the 4 onboard mix temperature hydronic
zones. Additional zones (boiler or mix) can be added using the tN4 Expansion terminals.
