VAV/Zone Controller 8
Slaved Zone Damper Wiring
For large zones it may be necessary to have more than one air damper
controlled by a VAV/Zone controller and its associated space sensor.
The Orion system allows for connecting up to two additional slaved
zone dampers to the master VAV/Zone controller. Slaving is not avail-
able for pressure independent damper applications.
Note: Each slaved actuator is considered a modular device rated
at 6 VA each. This 6 VA load must be included in the
transformer sizing and branch circuit calculations for the
Power/Comm board. See the previous section regarding
transformer sizing of the Power/Comm board for com-
plete information.
Two Slave Wiring Adapters (OE267) consisting of a slave wiring inter-
face card and modular cable are supplied with the OE523 Round Slaved
Zone Damper, OE738 Slaved VAV/Zone Rectangular Damper Kit and
the OE282-03 Slaved VAV/Zone Damper Kit. These are required when
attaching slave actuator(s) to the master zone damper. One slave wiring
interface card should be mounted in the control enclosure of the master
VAV/Zone controller. It is mounted by fastening the plastic snap-track
to the control enclosure with sheet metal screws provided. The other
card is mounted in the control enclosure of the slaved zone damper.
Fasten it in the control enclosure of the slaved zone damper as was
previously done with the master VAV/Zone controller. Run 24 AWG
minimum wire between the slave wiring interface cards. Connect modu-
lar cables to the slave wiring interface cards and to the zone actuators
as shown. See Figure 6 for complete wiring details.
