Damper - Aprilaire 6000 Series Safety & Installation Instructions

DAMPER

• Run 2-conductor thermostat wire for spring
return dampers (normally open or normally
closed).
• Run 3-conductor thermostat wire for power
open/power close dampers.
• Multiple dampers for the same zone can be
wired in parallel as shown in FIGURES 7 & 8.
• Wire the dampers to the 6000 Series Hub:
NC – This terminal is used to power open
a normally closed damper. For power open
and power close dampers this terminal is
used to power open the damper.
NO – This terminal is used to power close a
normally open damper. For power open and
power close dampers this terminal is used to
power close the damper.
COM – This terminal provides a common
connection for the NC and NO terminals.
• If multiple transformers will be required,
wire them in parallel as shown. Before
wiring the transformers together, ensure
that they are connected in phase by
observing polarity marks or terminal
orientation on each transformer. See
FIGURE 9.
