Battery Location
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).
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.
INSTALLER MENU
To prevent changes that may affect 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 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
menu setting.
