Overview Control central heating and cooling fan coil systems radiators and convectors. Depending on the model it can be controlled by a low voltage SPST or SPDT switch pulse-width modulated 24 Vac signal or floating input modulating controller. Features Use with two-way or three-way valves. Double insulated actuator. Five foot plenum-rated cable. Quick and easy replacement of moving parts. Actuator head installation does not require draining the system. Selectable/switchable electronic fail safe normally open or normally closed. Available with valve bodies with 1000-series 2-way and 6000-series 3-way cartridges for new construction. All VC Series actuator-valve combinations provide 60 psi close-off.
