DIP Switch Options and Functions
Positioning the DIP switches in either the ON or OFF position enables
you to choose between two different options. The DIP switches are
located on the interior of your thermostat and may be accessed by
following the procedure for removing the thermostat from the sub-
base. The following list describes your DIP switch options.

Installation Instructions
It is recommended that installation be performed by a qualified installer.
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. You should avoid the following locations:
- behind doors or in corners where freely circulating air is unavailable
- where direct sunlight or radiant heat from appliances might affect
control operation
- on an outside wall
- adjacent to, or in line with, conditioned air discharge grilles, stair-
wells, or outside doors
- where its operation may be affected by steam or water pipes or
warm air stacks in an adjacent partition 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 arcing relay contacts
Removing the Thermostat from the Subbase
1. Insert a flat blade screwdriver or a 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 sepa-
rate from the subbase. Some models require more force than others
when separating due to the number of terminals used.
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 con-
trol wires protruding from the wall and, using the subbase as a tem-
plate, mark the location of the two mounting holes (exact vertical
mounting is necessary only for appearance).
5. Use the supplied anchors and screws for mounting on drywall or plaster;
drill 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 the wall affecting the thermostat.
Replacing the Thermostat on the Subbase
1. Position the thermostat on the hinged tabs at the top of the subbase.
2. Gently swing the thermostat down and press on the bottom center edge
until it snaps in place.
Description Of Icons
Display icons vary according to the model. Your thermostat may not display
all of the icons shown.
Thermostat Cover Lock
If desired, insert the plastic lock
piece into the bottom of the mount-
ed base. The ends of the lock piece
should fit snugly under the lock pins
extending from the bottom of the
mounted base. The tab in the middle
of the lock piece should extend
downward from the mounted base.
To release the locking mechanism,
press the lock piece up and into the
base while gently prying open the
cover at the same time. Use caution
to avoid cracking the thermostat
base or cover.

Installing The Resistor (Provided)
Programmable thermostats with solid state equipment outputs require a
minimum of 80 mA AC (0.08A) of current draw to ensure switching integrity.
1. The installer must be a qualified service technician.
2. Read the instructions carefully. Failure to do so may damage the product
or cause a hazardous condition.
3. Connect the resistor leads to the equipment terminal strip across the Y or
G (as required) and the 24VAC common terminals. Avoid contact with any
other terminals or components within the equipment. Connect either end
of the resistor to the terminals (non-polarized) and firmly tighten the screw
terminals.
Notice
The resistor will become warm during equipment operation. This is normal.

Transformer Wiring Diagram
If the transformer
common terminal is
not available, con-
sult the equipment
manufacturer.
The thermostat will be held in the Night program until the
user resets the clock. The thermostat will display AC when the
24 VAC is not supplied. One of the unique features of your ther-
mostat is that there is no battery required to maintain your select-
ed setpoints in the event of a power loss, since the memory is
unaffected by power failures of any duration. There is no reason
to re-program the setpoint temperatures or start times since the
thermostat will retain these program parameters.
Power Outages & Power Failures During Regular Program Schedule
Should your power fail at any time during the regular program, the thermo-
stat will maintain the clock internally for up to 30 minutes. If the power has
not been restored during this time period, the clock will stop. When the
power is restored, the thermostat clock defaults to a flashing 12:00 AM.
