Not sure what type Changeover system? Check the existing thermostat connections to help
determine this . If the original system had an orange wire connected to an “O” terminal, then
this is a “changeover with cool” system . If there was a brown wire connected to a “B” terminal,
then this is a “change over with heat” system . Set the Changeover setting accordingly .
NOTE: If heating comes on when cooling is expected or vice versa, switch the “Changeover
Type” to the opposite setting.
