For retrofit installations, refer to the existing thermostat connections to help determine
correct C/O type setting. If the original system had an orange wire connected to an “O”
terminal, then it is a “changeover with cool” system. If there is a brown wire connected to
the “B” terminal, then it is a “change over with heat” system. NOTE: if you get cooling
when expect heating (or heating when you expect cooling), change the C/O type to the
other selection.
