ARD or ZD Dampers
Wire the ARD or ZD Damper to the panel as shown in Fig. 8.
Multiple dampers can be wired in parallel. Up to five ARD or
ZD dampers can be connected in parallel to one zone. If five to
ten dampers are connected to the panel an additional 40VA
transformer must be connected to the panel.

RRD
Wire the RRD dampers to the panel as shown in Fig. 9. Two or
more RRD can be wired in tandem as shown in Fig 10. Up to
12 RRD can be wired to one zone. Power the panel with one
40VA transformer if up to 12 dampers are connected to the
panel. Power the panel with two 40VA transformers if up to 26
RRD are connected to the panel.

MARD Dampers or Dampers using ML6161
Motor Actuator
Wire the MARD Damper or other damper using the ML6161
Actuator to the panel as shown in Fig. 11. These floating
control actuators are controlled as two-position devices on the
W8835 panel.
The ML6161 motor causes the damper LED to illuminate green
constantly. To restore damper position indication, mount end
switch 201052B onto the ML6161.

Transformer
Wire the transformers to the panel (see Fig. 12). One 40 VA, 24
Vac transformer is required to operate the panel and up to five
ARD or ZD dampers. The transformer is connected to
terminals R and C. The auxiliary transformer is required if up to
ten dampers are connected to the panel. It is wired to terminals
T1 and T2. If more than five ARD or ZD dampers are required
for one zone of if more than ten ARD or ZD dampers are
required for the W8835, use the Slave Damper Control Relay
(SDCR). Locate the XFRM jumper shown in Fig. 12. These
jumpers are shipped in the open, disconnected position. This is
the correct position when two transformers are used. When
using one transformer to power the panel, place the jumpers in
the closed position. Do this by removing the jumpers and
installing them so they cover both of their respective pins. If
preferred, one 75 VA transformer may be used on this panel
instead of two 40 VA. If this is done, leave the jumpers in the
open, disconnected position and install a jumper between R
and T1. Wire the transformer to R and C.
