Not sure which Changeover type?
Check the existing thermostat connections to help determine
this.

If the original system had an orange wire connected to
the “O” terminal, then this is a “changeover with cool”
system.
x
If there was a
Brown
wire connected to the “B” terminal,
then this is a “change over with heat” system.
x
Set the Change Over setting accordingly.
CAUTION:
These are typical wiring colors/connections
and may differ.
x
If heating comes on when cooling is expected or
vice versa, change the “Change Over Type” to the
opposite setting.
