Not sure what type Changeover system? Check the exis ng thermostat connec ons 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 se ng accordingly.

NOTE: If heating comes on when cooling is expected or vice versa, switch the “Changeover

Type” to the opposite setting.
