W8835 ENVIRAZONE PANEL

68-0258—04
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.
