Terminal AI1 / AI1: 4 - 20 mA FAN interlocking control by external input
• FAN mode is switched by external 4 - 20 mA input.
• Both FAN control with 4 - 20 mA input and FAN mode change with remote controller are valid, but boost priority is
given.
• The FAN priority control is switched by the DN setting of [4A0].
• 0000: Default (no change in FAN mode by 4 - 20 mA input)
• 0001: FAN control by 4 - 20 mA input, but priority is given to FAN control from the outdoor unit
• 0002: FAN control 4 - 20 mA input with priority
• The FAN mode switching threshold value for 4 - 20 mA input can be changed in the DN setting (See the table as
below).
* Terminal AI2 / AI2 cannot be used.
* The change in FAN speed with 4 - 20 mA input is also reflected in the 0 - 10 V output of AO1 / AO1.
