Ruskin model ZRC020 is a hand-held, battery operated, power supply and damper positioner used exclusively on Ruskin's ZPD25 Zone Pulse Damper. The damper utilizes a 12 volt powered actuator that is wired to a remote location (either in a wall box or diffuser). The ZRC020, when plugged into the RJ11 connector at the remote location, provides the power necessary to position the damper during the test and balancing process. One ZRC020 may be used to position all of the ZPD25 dampers at various locations throughout the building. The ZRC020 takes the cable out of the cable drive system.
