How to read curves
● Whenever the indoor unit operates, the
duct fan operates.
(1) Connect the optional multiple remote
controller adapter (PAC-SA88HA-E)
to the connector CN51 on the indoor
controller board.
(2) Drive the relay after connecting the
12 V DC relay between the Yellow
and Orange connector wires.
Use a relay of 1W or smaller.
MB: Electromagnetic switch power
relay for duct fan.
X: Auxiliary relay (12 V DC LY-1F)
Be sure to secure insulation
material by tape, etc.
