WIRING

Refer to equipment manufacturer’s instructions for specic system wiring information. After
wiring, see INSTALLER MENU for proper thermostat conguration. Wiring table shown are

for typical systems and describe the thermostat terminal functions.

Terminal Designations Terminal Function

RC* Power for Cooling

RH* Power for Heating

O/B

Y** Cooling Relay

G Fan Relay

W** Heating Relay

C

*When both RC and RH wires are present, cut RC/RH jumper (see next page).
**For heat pump systems, add a jumper wire to connect terminals Y and W

Changeover Terminal-Energized in Heat (B) or Cool (O)

Common wire for 24V (optional with batteries)

Leveling Thermostat

Leveling is for appearance only and

will not aect thermostat operation.

Precautions

• Do not exceed the specication 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.

Do not use on circuits exceeding specied voltage.

Higher voltage will damage control and could

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

cause shock or re hazard.

and/or property damage.

To prevent electrical shock and/or equipment

damage, disconnect electrical power to system,

at main fuse or circuit breaker box,until

installation is complete.

Baery Locaon

Premium AA alkaline batteries
are required when C-wire is
not available. When C-wire is

1

available, the batteries provide
a back-up source of power (this
will maintain the clock in the

2

event of a power outage).

1.) Gas/Elec Switch

If the system is a heat pump or electric furnace, the GAS/ELEC Switch must be set to

Elec. If your system is a gas or oil furnace, the switch must be set to Gas.

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.

3.) RC/RH Jumper Wire

This thermostat electrically connects the RC and RH terminals so a jumper wire is not

required. If the application provides a separate wire for RC and RH, clip the RC/RH
jumper. This will isolate both terminals so they can be independently used.

INSTALLER MENU

To prevent changes that may aect system performance, this thermostat has an INSTALLER’S
MENU and an USER MENU. The INSTALLER’S MENU provides access to every option, while
the USER MENU provides access to items that will not aect 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 and Back to navigate through menu items. Press or to change
a menu setting.
