Zone Valve Control, Five Zones with Priority
The Zone Valve Control 305V connects up to five thermostats and operates zone valves to provide heating to a zoned hydronic heating system. The 305V operates a system pump whenever a zone valve opens. Zone 1 can operate either a zone valve or a circulator to provide heat to an indirect domestic hot water tank with optional priority over zones 2 through 5. The 305V includes optional exercising to prevent circulator seizure when not in use, and optional post purge operation of the domestic hot water tank to maximize energy savings. The 305V provides a RoomResponseTM signal to modulating-condensing boilers to optimize comfort while improving boiler efficiency.
