MERCURY NOTICE
If this control is replacing a control that contains
mercury in a sealed tube, do not place your old
control in the trash. Dispose of properly.
Contact your local waste management authority
for instructions regarding recycling and the
proper disposal of an old control.

Fig. 1. Select 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.
Separate Wallplate from
Thermostat
1. Separate the wallplate from the thermostat. See
Fig. 2.
Fig. 2. Separate wallplate from thermostat.
Install Wallplate (See Fig. 3)
Mount the thermostat horizontally on the wall:
1. Pull the wires through the wire hole on the wallplate.
2. Position the wallplate on the wall with the arrow
pointing up. Level the wallplate for appearance only.
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and drill two
3/16 in. holes in the wall (if drywall) as marked. For
firmer material such as plaster, drill two 7/32 in.
holes. Tap the wall anchors (provided) into the
drilled holes until flush with the wall.
5. Pull the wires through the wire hole on the wallplate
and position the wallplate over the wall anchors.
6. Insert the mounting screws into the wall anchors
and tighten.
Fig. 3. Install wallplate.
WIRING
IMPORTANT
— All wiring must agree with applicable codes,
ordinances and regulations.
— Use 18 gauge thermostat wire. Shielded cable is
not required.
NOTES:
— Sensor wires must have a cable separate
from the thermostat control cable.
— Refer to Table 2 for terminal designation
descriptions.
— See Fig. 7 through 17 for wiring diagrams for
specific equipment applications.
1. Select set of terminal identifications that correspond
to your system type (conventional or heat pump).
(See Fig. 4).
Fig. 4. Terminal identifications for system type.
2. Loosen screw terminals used for the application.

3. Insert the wires into the terminal block and tighten
each screw terminal. See Fig. 5.
Fig. 5. Insert wires into terminal block.
4. Push excess wire back into the wall opening and
restrict wires to the shaded area. See Fig. 6.
5. Plug the wall opening with nonflammable insulation
to prevent drafts from affecting the thermostat. Fig. 6. Restrict wires to shaded area of wire hole.
Table 2. Terminal Designation Descriptions.
NOTES:
1. When used in a single-transformer system,
leave metal jumper wire in place between Rc
and R. If used on a two-transformer system,
remove metal jumper wire between Rc and R.
2. Common wire is optional when thermostat is
used with batteries. When using separate
transformers for heating and cooling, the
common must come from the cooling
transformer.
3. If thermostat is configured for a heat pump in
the Installer Setup, configure changeover
valve for cool (O-factory setting) or heat (B).
4. Reference economizer literature for wiring
details. When set for economizer operation,
the A terminal provides the occupancy signal.
(Power indicates occupied.)
5. Sensor wires must have a cable separate
from the thermostat control cable.
Terminal “A” Wiring Details for
Economizers
— Wire the A terminal to the W7212 “N” terminal, or the
W7459 “TR” terminal.
— When using dual transformers at the thermostat, the
heating transformer must power the economizer.
— The A signal is powered from the R terminal and
energizes the economizer to signal occupied status
and drive the damper to the set minimum position.

POWER THE THERMOSTAT
You can choose from three methods to power the
thermostat:
• Batteries only (AAA alkaline).
• 24 Vac direct connection only.
• 24 Vac direct connection with battery backup (AAA
alkaline).
Wiring 24 Vac Common
• Single-Transformer System—Connect the common
side of the transformer to the C screw terminal of the
thermostat wallplate. Leave the metal jumper wire in
place between Rc and R.
• Two-Transformer System—Connect the common side
of the cooling transformer to the C screw terminal of
the thermostat wallplate. Remove the metal jumper
wire between Rc and R.
Installing Batteries
1. Install three AAA alkaline batteries on the back of
the thermostat as marked. See Fig. 22.
Fig. 22. Installing batteries.
2. Locate and remove the tab labeled Remove. See
Fig. 23.
IMPORTANT
This tab must be removed in order to set the
real-time clock.
Fig. 23. Remove tab labeled REMOVE from
thermostat back.
Setting Calendar and Time
Setting Calendar
This thermostat is designed to, under normal use,
automatically keep current time and day in memory for up
to ten years once the calendar is set. There are two ways
to set the calendar for this thermostat:
SETTING CALENDAR WHEN THERMOSTAT IS FIRST
POWERED
When the thermostat is first powered, the display is ready
to set the calendar and time. The thermostat proceeds
through a sequence of setup screens. See Fig. 24.
SETTING CALENDAR AFTER THERMOSTAT IS
ALREADY FUNCTIONING
See steps 1 through 4, in the Advanced Settings section,
to set year, month and day.
Fig. 24. Setting calendar and time after initial powerup.
Mount Thermostat to Wallplate
1. Align the terminal screw blocks with the pins on the
back of the thermostat.
2. Push the thermostat straight onto the wallplate until
it snaps into place. See Fig. 25.

Advanced Settings
The thermostat has advanced settings to match the HVAC
system. These settings can be adjusted to match specific
needs. Access to these settings is obtained as follows:
1. From the main screen, press SYSTEM. Five blank
touch keys show on the bottom of the screen
between DONE and CANCEL.
2. Press and hold the two blank keys on either side of
the center blank key for approximately five seconds.
(See Fig. 26.)
3. The Setup Number displays to the lower-left area of
the screen. It is a four-digit code beginning with
zero. The current setting is displayed to the right.
NOTE: To cycle through the Setup Numbers, press the
up or down arrow.

Installer System Tests
Use the Installer System Test to test the heating, cooling
and fan. Refer to the latter portion of Table 4.
CAUTION
Equipment Damage Hazard.
Minimum compressor off time is bypassed
during Installer System Test
Avoid cycling compressor quickly.
IMPORTANT
Use Installer System Test to test heating, cooling
and fan. The setting chosen for System Type
(Installer Setup Number 0170) can prevent some
System Test Numbers from appearing.
