Mounting the SMART 3000 Thermostat
IMPORTANT: The SMART 3000 can only be as accurate as the onboard
temperaturesensor,oritsoponalremotetemperaturesensor(s)
permit. The SMART 3000 should be mounted in a location that is
typical of the ambient room temperature. Do not install near the
floor,inadraft,behindadoor,oronanon-insulated,exteriorwall.
InstalltheSMART3000awayfromexposuretosunlightandfourto
five feet (1.2 to 1.5 m) above the floor.
Figure 1
• Locate the slot on the housing at the bottom. Take note of the hinge points
and the connection between the two halves.
• Insert a screwdriver or coin into the slot and twist. This will separate the two
halves.

5
• Continue to swing the top half upward. This will release the tabs holding the
top half in place.
• Pull the control wires through the large opening in the base plate.
• Position the base plate on the wall and attach it with appropriate fasteners
(two screws with drywall anchors are supplied). The base plate should be
visibly level.
• Block any holes where wires are pulled through a wall opening. This will
prevent drafts from entering the back of the thermostat.
Do not use
these holes for
mounting.
