when the airflow direction also
changes.
(Power On indicator)
Indicates that the power is on.
Note:
● “PLEASE WAIT” message
This message is displayed for approximately 3 minutes when power is supplied to the indoor unit or when the unit is recovering from a power failure.
● “NOT AVAILABLE” message
This message is displayed if an invalid button is pressed (to operate a function that the indoor unit does not have).
If a single remote controller is used to operate multiple indoor units simultaneously that are different types, this message will not be displayed as

Operation in conjunction with duct fan (Booster fan)
●Whenever the indoor unit is operating, the duct fan
operates.
(1)Connect the optional multiple remote controller
adaptor (PAC-SA88HA-E) to the connector CN51
on the indoor controller board.
(2)Drive the relay after connecting the 12V DC relay
between the Yellow and Orange connector lines.
(w)Use a relay of 1W or smaller.

The drain pump turns ON for the specified amount of time when any of the
following conditions is satisfied:
1 ON for 3 minutes after the operation mode is switched from COOL or DRY to
another operation mode (FAN).
2 ON for 6 minutes after the drain sensor is determined to be submerged
using the liquid level detection method given below.
3 ON for 6 minutes after indoor piping (liquid piping) temperature – indoor
room temperature [-18°F, AND the drain sensor input is at the short or
open level.
(If condition 2 or 3 is still being met after the drain pump has been turned ON
for 6 minutes, the drain pump is kept ON for a further 6 minutes.)
2-2. Liquid level detection method
The liquid level is detected by determining whether or not the drain sensor is
submerged, based on the amount the temperature rises after self-heating the
sensor. This process is performed if any of the following conditions is satisfied:
1 Drain pump is ON.
2 Indoor piping (liquid piping) temperature – indoor room temperature [-18°F
3 Indoor piping (liquid piping) temperature or indoor room temperature is at
the short or open level temperature.

Linear expansion valve
1 Operation summary of the linear expansion valve
• Linear expansion valves open/close through the use of a stepping motor after receiving the pulse signal from the indoor
controller board.
• Valve position can be changed in proportion to the number of pulse signals.
