The 99-BC02, 99-BC03, 99-BC04 ventilation controls may either be installed onto a flush mounted electrical switch box or
surface mounted onto a wall. Only one main control should be installed into a ventilation system.

desired location on the wall and
mark the wall for the desired
screw holes (figure B).
3.
For mounting the main control
without a Decora plate, break off
the top and bottom tabs than
position the back plate in the
desired location on the wall and
mark the wall for the desired
screw holes (figure C)
4.
Remove the back plate from the
wall and mark the hole for the
wires centered between the two
screw holes (figure B or C).
5.
Drill two 1/8 in. holes for the
screws and wall anchors and drill
one 1 in. x 0.75 in. hole for the
wires.
6.
Pull the 3 wire 20 gauge (min.),
100 ft length (max.), through the
opening in the wall.
7.
Connect the wires to the R, G, and
Y terminals on the back plate
(figure B or C).
8.
Using the two supplied screws and
anchors, install the back plate on
the wall.
9.
Attach the face plate to the back
plate (figure A).
10.
Connect the 3 wire 20 gauge (min.), 100 ft length (max.), to the 3 (RED), 4 (YEL), and 5 (GRN) terminals located on
the HRV/ERV terminal block (figure D).
