INSTALLATION INSTRUCTIONS
Your new digital thermostat has been designed to
provide accurate control and display of room temper-
ature. In addition, it will also display all relevant infor-
mation pertaining to your system.
The clearly marked buttons and informative display
make it extremely easy to understand and simple to
use.
Please take a few moments to read the brief instruc-
tions and familiarize yourself with the various func-
tions in order to obtain maximum benefit from this
truly unique electronic control.
GENERAL INFORMATION
The thermostat normally displays room temperature,
mode of operation and whether heating is currently
on. The two buttons on the front of the unit allow
complete control of the equipment.
Raising or lowering the setpoints in heating is as sim-
ple as pushing a button. In addition, you may choose
to display the temperature in °F or °C.

POWER FAILURES
Your thermostat employs the latest developments in
solid state electronic technology.
One of the unique features of your thermostat is that
there is no battery required to maintain your selected
setpoints in the event of a power loss as the memory
is unaffected by power failures of any duration.
When power is restored, the thermostat will continue
operating as if the power had never been off.
TEMPERATURE ACCURACY
Full temperature accuracy will be realized only after
the thermostat has been installed and powered for at
least one hour.

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 a coin 1/8" into
the slot located in the bottom center of the thermo-
stat case and twist 1/4 turn. When you feel or hear
a “click,” grasp the case from the bottom two cor-
ners 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 verti-
cal mounting is necessary only for appearance).
5. Use the supplied anchors and screws for mounting
on drywall or plaster; drill two 3/16" (5mm) diame-
ter 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 thermo-
stat 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 pre-
vent drafts from the wall 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.
