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.
