Applications
The VR1816 circulator is a variable speed, high-efficiency wet rotor circulator
with an ECM permanent magnet motor. Operating modes include infinitely
variable fixed speed to fine tune any zone, self-adjusting constant pressure for
zone valve applications and self-adjusting proportional pressure for panel
radiators with thermostatic radiator valves. The VR1816 is not suitable for
chilled water or open loop potable water applications.
