The Switching Relay 306P connects up to six thermostats and operates circulators to provide heating to a zoned hydronic heating system. Zone 1 has optional priority over zones 2 through 6 and can be used to provide heat to an indirect domestic hot water tank. The 306P includes optional exercising to prevent circulator seizure when not in use, and optional post purge operation of the last operating zone to maximize energy savings. The 306P provides a RoomResponse (TM) signal to modulating-condensing boilers to optimize comfort while improving boiler efficiency.
