MOUNTING
STEP 3 (Wall and Surface Mounting)
If installing the unit onto a cabinet, wall, wood
header, rim joist, or mesh on an existing crawl
space vent, please use the unit or plastic
template to determine the mounting location.
Secure the mounting frame onto the surface
with the included wood screws. If using a
machine screw with nuts, you may need to drill
a hole. Note that models T8 and T8-N do not
include a plastic template.
STEP 3 (Foundation Block Mounting)
To install the unit onto a foundation brick or
block, mark the mounting hole locations using
the four corners of the metal face plate. Then
drill 5/16" holes with a drill bit. Install wall
anchors into openings and secure the unit into
the wall with four screws. Note that the models
T3 and T7 are designed for cabinet and wall
mounting, and do not include wall anchors and
larger type screws.

measured value exceeds your set value. The fans will stop running when the measured value falls
below your set value by the number set as the buffer. For low temperature or humidity triggers,
the fans will start running when the measured value falls below your set value. The fans will stop
running when the measured value rises above your set value by the number set as the buffer. The
speed the fans will run at is the speed set in (2) Fan Speed.

when the measured value exceeds your set value. When the measured value falls below your set
value, the fans will slowly decrease in speed until the fan stops. For low temperature or humidity
triggers, the fans will slowly increase in speed when the measured value falls below your set value.
When the measured value rises above your set value, the fans will slowly decrease in speed until
the fan stops, when the measured value rises above your set value. The max speed the fans will
reach is the speed set in (2) Fan Speed.
2.SPEED
In this mode, the fans will run non-stop regardless
of temperature or humidity. Pressing the up and down
buttons in this mode will change the speed of the fan.
