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).
