bDo not connect both O and B when wiring to a single stage heat pump. Connect O to O. Tape off B.

cTape off end of the wire with electrical tape and push the taped wire back into the wiring hole in the wall.

STEP 5. INSTALL THE BATTERIES

IMPORTANT

Three AA alkaline batteries are included with the thermo- stat. Batteries must be installed for programming and operation of the thermostat and the heating/cooling sys- tem.

Install the batteries in the wallplate so the positive terminals all point up (see illustration).
