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 Change Over setting
accordingly. (Caution: These are typical wiring colors/connections)
Note: If heating comes on when cooling is expected or vice versa, change the
“Change Over Type” to the opposite setting.
