MOUNTING THE OUTDOOR TEMPERATURE SENSOR
1.
Drill a 3/8" diameter hole in the duct of the fresh air inlet hood .
2.
Install the outdoor temperature sensor into the duct and use metal foil tap to secure it in place
and seal the opening . Run the wire toward the outside wall .
3.
Secure ductwork to the inlet hood duct while allowing the wire of the sensor to extend outside
of the insulation . Tape and/or mastic the duct as needed and properly insulate .
MOUNTING THE CONTROLLER IN A CLOSET RETURN PLENUM
NOTE:
Do not mount directly in the path of the outdoor air . Mount the control where it will
sense the relative humidity of the return air .
1.
Remove the wall plate from the control and put the rest of the control in a safe location until
after wiring is complete .
2.
Use spacers or brackets to mount the controller to an inside wall surface or return plenum/
duct surface that is at room temperature (i .e . do not mount to supply ductwork or to the air
handler/furnace) to space the wall bracket a minimum of ½” away from the surface .
3.
Mount the wall bracket to the surface using #8 screws (field supplied –
do not use flat head
screws)
and wall anchors (field supplied) if mounting to drywall . Ensure that there is room
for air to flow behind the wall bracket .
DO NOT install screws in the wall bracket anywhere
except intended mounting holes.
