Taco Variable Speed Outdoor Reset Control Circulators
Maximize the efficiency of your heating system
The Outdoor Reset Circulator controls the hot water supply temperature, so that the
heat supplied to the building equals the heat loss of the building. The
00-VR modulates the circulator to inject hot water from the boiler loop
into the radiant or reduced temperature loop while providing Outdoor
Reset to a heating system. Available in any style 003 - 0014, the 00-VR
also comes with a boiler sensor to protect against low return
temperatures. The 00-VR is the ultimate for protection, control, ease
of installation, and trouble-free operation.
