INSTALLATION
Wiring 24 Vac Common
• Single-Transformer System—Connect the common side
of the transformer to the C screw terminal of the
thermostat. Leave the metal jumper wires in place
between R and RC.
• Two-Transformer System—Connect the common side of
the cooling transformer to the C screw terminal of the
thermostat. Remove the metal jumper wire between R
and RC. Connect the hot side of heating transformer to
R and connect the hot side of cooling transformer to RC.
Selecting Discharge Air
Temperature Sensor Mounting
Locations
Refer to the guidelines below and Fig. 3–7 for mounting
locations of the Discharge Air Temperature Sensor.
Selecting Discharge Air Temperature
Sensor Mounting Location
1. Mount the Discharge Air Temperature Sensor on the
supply duct in a location where the air is mixed well.
Mount the Discharge Air Temperature Sensor out of
sight of the A-Coil/Heat Exchanger when possible.
See Fig. 3.
2. When possible, mount the Discharge Air Temperature
Sensor upstream of a Steam Humidifier, a Fan
Powered Humidifier or a Dehumidifier that is ducted
to the supply. See Fig. 4–5.
3. If space does not allow a Discharge Air Temperature
Sensor upstream of a Steam Humidifier or Fan
Powered Humidifier, mount the Discharge Air
Temperature Sensor downstream of the Humidifier.
See Fig. 4.
4. If a Bypass Humidifier is installed, mount the
Discharge Air Temperature Sensor downstream of the
Bypass Humidifier. See Fig. 6–7.

Selecting Thermostat Location
Install the thermostat about 5 ft. (1.5m) above the floor in an
area with good air circulation at average temperature. See
Fig. 9.
Fig. 9. Selecting thermostat location.
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 sun or appliances.
— Concealed pipes and chimneys.
— Unheated (uncooled) areas such as an outside wall
behind the thermostat.
Installing Wallplate
CAUTION
Electrical Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before wiring.
The thermostat can be mounted horizontally on the wall or
on a 4 in. x 2 in. (101.6 mm x 50.8 mm) wiring box.
1. If your thermostat has a button along the top of the
wallplate, press the button on top and pull to remove
the wallplate as shown. Updated models do not have
this button. On those models, pull evenly along the
sides and bottom of the thermostat to separate it
from the wallplate.
Fig. 10. Separate wallplate from thermostat.
2. Position and level the wallplate (for appearance only).
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and, if drywall,
drill two 3/16-in. holes in the wall, as marked. For
firmer material such as plaster, drill two 7/32-in.
holes. Gently tap anchors (provided) into the drilled
holes until flush with the wall.
5. Position the wallplate over the holes, pulling wires
through the wiring opening. See Fig. 11.
6. Insert the mounting screws into the holes and
tighten.
Fig. 11. Mounting wallplate.
7. Connect common side of transformer to C terminal.
Fig. 12. Connecting C wire to terminal block.
Wiring the Thermostat
1. Refer to Fig. 13. See Table 9 on page 84 for terminal
designations and “Wiring” beginning on page 84 for
more information.
2. Turn on 24 VAC NOW.

updated model without hinges, line the thermostat
up evenly with the wallplate and push the thermostat
evenly along the sides and bottom to snap it into
place.
