5.1. Dip switch functions
Located on the FTC2B printed circuit board are 4 sets of small white switches
known as Dip switches. The Dip switch number is printed on the circuit board next
to the relevant switches. The word ON is printed on the circuit board and on the Dip
switch block itself. To move the switch you will need to use a pin or the corner of a
thin metal ruler or similar.
Dip switch settings are listed below.
Make sure to turn off both indoor unit and outdoor unit power supplies before
changing the switch settings.
