Slaved Zone Damper Wiring
For large zones, it may be necessary to have more than one air damper
controlled by a VAV/Zone Controller Actuator Package and its associ-
ated space sensor. The WCC III system allows for connecting up to
two additional slaved zone dampers to the master VAV/Zone Controller
Actuator Package. Slaving is not available for pressure independent
damper applications.
Note: Each slaved actuator is 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 complete information.
Two Slave Wiring Adapters ( OE267) consisting of a slave wiring
interface 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 near the control enclosure of
the master VAV/Zone Controller Actuator Package. It is mounted by
fastening the plastic snap-track to suitable sheet metal mounting surface
with the sheet metal screws provided. The other card is mounted in the
control enclosure of the slaved zone damper. Run 24 AWG minimum
wire between the slave wiring interface cards. Connect modular cables
to the slave wiring interface cards and to the zone actuators as shown.
See Figure 14 for complete wiring details.
