NOTE ABOUT CRAWL SPACE & BASEMENT COMBINATION:
Depending on the square footage, the Sensor Control BT will be able to reduce the problems in the
crawl space and the basement. The unit should be installed in the basement , adjacent to the
crawlspace. An opening of at least 100 sq. inches in the adjoining wall, not higher than 4 inches
above ground level of the crawl space, will allow for the air to be drawn out of the crawl area into the
Sensor Control BT. A replenishment grille from the upstairs should be installed at the opposite end
of the crawl space allowing for the maximum circulation in the crawl before it reaches the opening in
the adjoining wall. If the square footage of the basement and crawlspace exceeds 1800 sq. ft. then a
separate additional unit is recommended for the crawl space in addition to the basement unit. A
separate replenishment air source vent from upstairs would be required, one in the crawl and one in
the basement.
SUMMER SERVICE BULLETIN FOR NEW INSTALLATION:
The summertime temperature in most basements remains at approximately 59º to 66º F (15 to 19º C)
whereas the air entering the basement from the upstairs of the house will generally be in the range of
75º to 85º F (24º to 29º C) with a relative humidity of 70 to 75%. This air will have a dew point (the
temperature of surfaces on which it will condense, including basement surfaces) in the range of 64º to
76º F (18 to 24º C).
When a Sensor Control BT is installed in these conditions, condensation may result, as the air from
the upstairs comes in contact with the colder surfaces (ie. Concrete basement floors, walls, etc.). The
Sensor Control BT's ventilation effect will, over time, increase the basement temperature and prevent
this condition. However, during the initial operating season, a small amount of heat may have to be
added temporarily to the basement to increase its temperature.
If air conditioner is present in the house, close all ducts to the basement and also reduce speed
exhaust to medium (2).
REMEMBER THESE FUNDAMENTAL RULES:
Do not store anything within a radius of 3 to 4 feet (90 to 120 cm) around the base of the
Sensor Control BT. These articles would interfere with the circulation at floor level.
Make sure that the air from the entire basement can reach the Sensor Control BT.
NOTE: Keep interior doors in the basement open, or undercut doors by 2.5 inches, or install
grilles in lower wall or at bottom of doors, minimum 100 sq. in.
