terminal. If another wire is attached to the C terminal, check withermostat.com
for help. Attach the O wire to the O/B terminal. On the Type of Changeover Valve
screen, select Cooling Changeover Valve. See page 28. If your old thermostat
had an O wire and not a B wire, attach the O wire to the O/B terminal.
