INSTALLATION INSTRUCTIONS
LOCATION
To ensure proper operation, the thermostat should be
mounted on an inside wall in a frequently occupied
area of the building. In addition, its position must be
at least 18" (46cm) from any outside wall, and approx-
imately 5' (1.5m) above the floor in a location with
freely circulating air of an average temperature.
BE SURE TO AVOID THE FOLLOWING LOCATIONS:
- behind doors or in corners where freely circulating
air is unavailable
- where direct sunlight or radiant heat from appli-
ances might affect control operation
- on an outside wall
- adjacent to, or in line with, conditioned air dis-
charge grilles, stairwells, or outside doors
- where its operation may be affected by steam or
water pipes or warm air stacks in an adjacent parti-
tion space, or by an unheated/uncooled area
behind the thermostat
- where its operation will be affected by the supply
air of an adjacent unit
- near sources of electrical interference such as arc-
ing relay contacts
THERMOSTAT INSTALLATION
1. Insert a flat blade screwdriver or coin 1/8" into the slot
located in the bottom center of the thermostat case and
twist 1/4 turn. When you feel or hear a click, grasp the
case from the bottom two corners and separate from
the subbase as shown in the diagram at the right. Some
models require more force than others when separating
due to the number of terminals on the subbase.
2. Swing the thermostat out from the bottom.
3. Lift the thermostat up and off the subbase.
4. Place the rectangular opening in the subbase over the
equipment control wires protruding from the wall and,
using the subbase as a template, mark the location of
the two mounting holes (exact vertical mounting is nec-
essary only for appearance).
5. Use the supplied anchors and screws for mounting on
drywall or plaster; drill two 3/16" (5mm) diameter holes
at the marked locations; use a hammer to tap the nylon
anchors in flush to the wall surface and fasten subbase
using the supplied screws. (Do not overtighten!)
6. Connect the wires from your system to the thermostat
terminals as shown in the wiring diagrams. Carefully
dress the wires so that any excess is pushed back into
the wall cavity or junction box. Ensure that the wires are
flush to the plastic subbase. The access hole should be
sealed or stuffed to prevent drafts from affecting the
thermostat.
REPLACING THE THERMOSTAT
ON THE SUBBASE
1. Position the thermostat on the hinged tabs located at
the top of the subbase.
2. Gently swing the thermostat down and press on the
bottom center edge until it snaps in place.
