Input Name
AI1 FAN interlock
Analog Input 1 (4 - 20 mA)
• 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
