Dip Switch Setting - Mitsubishi Electric PAC-IF081B-E Installation Manual

5. DIP switch setting

5.1 DIP switch functions
Located on the FTC printed circuit board are 7 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 in Table 5.1.1.
Only an authorised installer can change DIP switch setting under one's own re-
sponsibility according to the installation condition.
Make sure to turn off both indoor unit and outdoor unit power supplies before
changing the switch settings.
For multiple outdoor units control with FTC (sub), see section 10.3.2.
