product or cause a hazardous condition.
2. Check the ratings given in the instructions to make sure the product is suitable for
your application.
3. The installer must be a trained, experienced service technician.
4. After completing the installation, use these instructions to check out the operation of
the product.
Selecting Location
Install the thermostat about 5 feet (1.5m), above the floor in an area with good air
circulation at average temperature. See Fig.4.
Do not install the thermostat where it can be affected by:
---Drafts or dead spots behind doors and in corners.
---Hot or cold air from ducts.
---Radiant heat from the sun or appliances or concealed pipes and chimneys.
---Unheated or uncooled areas such as an outside wall behind the thermostat.
Mounting Means:
Mounts directly on the wall in the living space using mounting screws and anchors
provided or on a horizontal 2x4 electrical box.

Installing the Wall plate
CAUTION
Electrical hazard! Can cause electrical shock or equipment damage. Disconnect
power before wiring.
The thermostat should be mounted horizontally on the wall.
If mounting on dry wall:
1. Position and level the wall plate on the wall.
2. Use a pencil to mark the inner mounting holes.
3. Remove the wall plate from the wall and drill two holes in the wall as marked. Gently
tap the anchors (provided) into the drilled holes until flush with the wall.
4. Position the wall plate over the holes, pulling wires through the wiring opening. See
Fig.5.
5. Insert the mounting screws (provided) into the holes and tighten.
If mounting on a horizontal 2x4 electrical box:
1. Align the outer holes with the holes on the electrical box.
2. Insert machine screws (not provided) into the holes.
3. Pull wires through the wall opening.
4. Level the wall plate and tighten the screws.

11
Note: If you are mounting on a vertical 2x4 electrical box or on a 4x4 electrical box you
will need to purchase an adapter ring.

WIRING
All wiring must comply with local electrical codes and ordinances.
1. See Table 1 and Fig.6 for terminal designation descriptions. Insert wires in the
terminal block under the loosened screws. See Fig.7.
2. Securely tighten each screw.
3. Push excess wire back into the hole in the wall.
4. Plug the hole with nonflammable insulation to prevent drafts from affecting the
thermostat.

NOTES:
1. When used in a single-transformer system, leave the metal jumper wire in place
between RC and R. If used on a two-transformer system, remove the metal jumper
wire between RC and R.
2. If the thermostat is configured for a heat pump system, configure the changeover
valve for energized on cool or heat in the Installer setup.
3. The L terminal is an input for optional system alarm monitoring. If the terminal is
connected to 24V, ES (emergency signal) will appear on the screen, overriding the
room temperature display.
