1. PFD-P250VM-E
u
Note: 1. The dotted lines show field wiring.
2. The address setting of the indoor unit should always be odd.
3. The outdoor unit to which the indoor unit is connected with the transmission line,
the address of the outdoor unit should be the indoor unit +50.
4. Mark indicates terminal bed, connector, board insertion connector
or fastening connector of control board.
