ACTUATOREXPANSION

Note:1.) A Slave Wiring Adapter consisting of a bypass & slave interface cardand modular cable is supplied with the Round Slaved-Zone Damper,Rectangular Slaved-Zone Damper Kit and the Slaved Zone Package. It isrequired when attaching slave actuator(s) to the master zone damper.The bypass & slave interface card should be mounted in the controlenclosure of the master zone damper. It is mounted by fastening theplastic snap-track to the control enclosure with sheet metal screws.Connect modular cables to the bypass and slave interface card and themaster zone actuator as shown.
