Description
The Zone Valve Control 306V
connects up to six
thermostats and operates zone
valves to provide heating to
a zoned hydronic heating
system. The 306V 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
6. The 306V 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
306V provides a
RoomResponseTM signal to
modulating-condensing boilers
to optimize comfort while
improving boiler efficiency.
