1, Read these instructionscarefully. Failure to follow
the instructions can damage the product or cause
a hazardous condition.
2. Check the ratingsgiven in the instructions and on
the product to make sure the product is suitable for
your application.
3. Installer must be a trained, experienced service
technician.
4. After completing installation, use these instructions
to check outthe product operation.
Location
Install the thermostat about 5 II (t .Sin)above the floor in
an area with good air circulation at average temperature,
See Fig. 1,
DOnot install the thermostat where it can be affected by:
-- drafts, or dead sppts behind doors and incornere.
-- hot orcold air from ducts.
-- radiant heat from sun or appliances,
mconcealed pipes and chimneys.
-- unheatad (unccoled) areas such as an outaide wall
behind the thermostat.
WallplateInstallation
The thermostat can be mounted horizontally on the wall
or on a 2 in. x 4 in.wiring box. Position wallptste
hodzordally on the wail oron a 2 in, x 4 in. widng box.
1. Position and level the waitplate (for appearan¢_
only).The thermostat will func_on properly even
when not level.
2. Use a ppnciJ to mark the mounting hoJes.See
Fig. 2.
3. Remove the wallptata from the wall and ddfltwo
3/16 inch holes inthe wall (if drywall) as marked.
For firmer material such as plaster, ddll two 7/32
inch holes. Gently tap anchors (provided) intothe
drilled holes until flushwith the wall.
4. Position the wallplate over the holes, pulling wires
through the wiring opening.
6. Loosely insert the mounting screws intothe holes.
6. Tighten mounting screws.
WIRING
All wiring must comply with local electrical codes and
ordinances. Refer to Fig. 3 for typlcst hookup. A letter
codeis located near each terminal for identification.

SETrlNGS
Systemand FenSettings
The system defeult setting is Heat and the fan default
setting is Auto. Use the System and Fan keys to change
the settings, See Fig, 7. The fan settings can be set for
each program period individually.The system selection is
for all the program periods.
System settings control the thermostat operation as
follows:
Em Heat: Emergency heat relay Is on conttnuousty.
Thermostat cycles highest stage of heat. Cooling
system is off.Compressor isde*energized.
Heat: The thermostat controls the beating.
Off: Both the heating and cooling are off.
Cool:The thermostat controls the cooling.
Auto:The thermostat automatically changes between
heating and cooling operation, depending on the
indoortomporature.
Fan settingscontrol the system fan as follows:
On: Fan operates continuously.
Auto: Fan operates with equipment.
LEDIndication
TwoLED indicators are located in the upper right of the
thermostat.They indicate when a CHECK or FAIL signal
is sentto thethermostat from the system. See Fig. 3.
