Air Drafts In Wall Enclosure
Older homes may experience air flowing (drafts) from the inside wall cavity into or
out of the wall enclosure depending on the draft situation. If this CONTROL is
experiencing problems sensing condensation, sealing any enclosure openings is
needed. The wall enclosure is easy to seal with standard painter's caulking and a
caulking gun. To begin you must disconnect all electrical power to the CONTROL
before sealing the openings. Unscrew all box switches and pull them forward to
allow access to the back of the enclosure. Apply caulking into all openings in the
enclosure, even the very small ones. Seal every opening and around electrical
wires at their entering point. Also seal the perimeter around the enclosure between
the wall board and the enclosure. This will stop heat loss and allow this CONTROL
to sense the room and not the drafts in the walls.
