WIRING
Refer to equipment manufacturer’s instructions for specic system wiring information. After
wiring, see INSTALLER MENU for proper thermostat conguration. Wiring table shown are
for typical systems and describe the thermostat terminal functions.
THERMOSTAT INSTALLATION
Precautions
• Do not exceed the specication ratings.
• All wiring must conform to local and national electrical codes and ordinances.
• This control is a precision instrument, and should be handled carefully. Rough handing or
distorting components could cause the control to malfunction.
WARNING
!
Do not use on circuits exceeding specied voltage.
Higher voltage will damage control and could
cause shock or re hazard.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will burn
out thermostat and could cause personal injury
and/or property damage.
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electrical power to system
at main fuse or circuit breaker box until
installation is complete.
Leveling Thermostat
Leveling is for appearance only and
will not aect thermostat operation.

INSTALLER MENU
To prevent changes that may aect system performance, this thermostat has an INSTALLER’S
MENU and a USER MENU. The INSTALLER’S MENU provides access to every option, while the
USER MENU provides access to items that will not aect system performance. To access the
INSTALLER’S MENU press the Menu button for 8 seconds. The display will show item 30 in
the table below. Use Next to navigate through menu items. Press or to change a menu
setting.

1.) W2/E Jumper Wire
This thermostat electrically connect the W2 and E terminals so that you do not need to
do this with a jumper wire. If your system has separate W2 and E wires, clip the W2/E
jumper located on the back of the thermostat. This will isolate both terminals so they can
be used independently.
2.) O/B Terminal Switch
The O/B switch on this thermostat is factory set to the O position. This will accommodate
the majority of heat pump applications, which require the changeover relay to be
energized in Cool. If the heat pump being installed requires a B terminal to energize the
changeover relay in Heat, the O/B switch must be moved to the B position.
Baery Locaon
Premium AA alkaline batteries
are required when C-wire is
not available. When C-wire is
available, the batteries provide
a back-up source of power (this
will maintain the clock in the
event of a power outage).

CAUTION
!
To prevent compressor and/or property damage, if the outdoor temperature is below 50°F,
DO NOT operate the cooling system.
Do not allow the compressor to run unless the compressor oil heaters have been operational
for 6 hours and the system has not been operational for at least 5 minutes.
TEST EQUIPMENT
Turn on power to the system.
Fan Operation
If your system does not have a G terminal connection, skip to Heating System.
1.) Move fan switch to On position. The blower should begin to operate.
2.) Move fan switch to Auto position. The blower should stop immediately.
Heating System
1.) Move System Switch to Heat position. If the auxiliary heating system has a standing
pilot, be sure to light it.
2.) Press to adjust thermostat setting to 1° above room temperature. The heat pump
system should begin to operate and the thermostat will indicate Heat On.
3.) Press to adjust thermostat setting to 3° above room temperature. The auxiliary heat
should begin to operate and the thermostat will indicate Heat On Auxiliary.
4.) Press to adjust thermostat setting 1° below room temperature. The heating system
should stop operating and the thermostat should indicate Heat.
Auxiliary System
1.) Move System Switch to Aux position. If the auxiliary heating system has a standing pilot,
be sure to light it.
2.) Press to adjust thermostat setting to 1° above room temperature. The auxiliary heating
system should begin to operate and the thermostat will indicate Heat On Auxiliary.
3.) Press to adjust thermostat setting 1° below room temperature. The auxiliary heating
system should stop operating and the thermostat should indicate Heat Auxiliary.
Cooling System
1.) Move System Switch to Cool position.
2.) Press to adjust thermostat setting 1° below room temperature. The blower should
come on immediately on high speed, followed by cold air circulation. The thermostat will
indicate Cool On. There can be up to a 5 minute delay. (see INSTALLER MENU, item 50)
3.) Press to adjust thermostat setting to 1° above room temperature. The cooling system
should stop operating and the thermostat will indicate Cool.
Note: If Starting Soon is shown on the display, the compressor lockout feature is operating.
There will be up to a 5 minute delay before the compressor turns on.(see INSTALLER MENU,
item 50)
