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
