TEKMAR 304V FOUR ZONE VALVE CONTROL WITH PRIORITY

The Tekmar 304V Four Zone Valve Control connects up to four thermostats and operates zone valves to provide heating to a zoned hydronic heating system. The Tekmar 304V 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 4. The Tekmar 304V 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 Tekmar 304V provides a Room Response signal to modulating condensing boilers to optimize comfort while improving boiler efficiency.
