THERMOSTAT INSTALLATION

WIRING

Refer to equipment manufacturer’s instructions for specific system wiring information. After wiring, see INSTALLER MENU for proper thermostat configuration. Wiring table shown are for typical systems and describe the thermostat terminal functions.

*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

Precautions

• Do not exceed the specification 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.

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 affect 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 affect 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.
