damper. The linkage rod is shipped connected to the return air
damper. To connect the linkage to the fresh air damper, open
the fresh air damper and insert the rod through the opening in
the damper bracket. With the rod through the fresh air damper
bracket, close the fresh air damper tightly, and tighten the set
screw on the fresh air damper bracket as shown.
Note: Linkage rod should be flush with the back of the
return air damper bracket.
Step 10:
Route the blue and violet wire from the Logic Module “+” and
“S” terminals through the lower bushing provided in the fresh
air damper as shown. These wires will be connected to the
Enthalpy Control mounted on the fresh air hood as shown in
