Control details
No drain pump operation
However, when the control changes from COOL or DRY
operation, the drain pump operates for 3 minutes.

to HEAT operation. ···[Downward C]
(2) Air flow direction
[Horizontal]→[Downward A]→Downward B]→Downward C]→[Swing]
(3) Determining position (When the timing motor of AC 200-240V)
Control each air outlet angle considering the starting OFF →
ON of limit switch to be a standard position (Horizontal or
shutter).
When the standard position can not be determined for 10
minutes, the vane stops at the arbitrary position.
(Vane swing motion for 10 minutes)
(4) Restriction of vane position
1 The vane is horizontally fixed for the following modes.
(The control by the remote controller is temporally invalidated
and control by the unit.)
•Compressor OFF mode (Thermoregulating, etc.)
•Hot adjuster [Extra low] mode
•Cool prevention mode (Determining except for Heat area)
•Heat defrost mode
•Piping (Condenser/ Evaporator) temperature is 37: or less.
2 Short cycle protection (Only model PLH-P1.6, 2, 2.5KAH
PLA-P1.6, 2, 2.5KA PLH-P•KAH.UK PLA-P•KA.UK
supports this control mode.)
If the short cycle status was detected by the vane setting
(downward blow C), the vane angle (downward blow B) is
restricted for short cycle protection. This control mode only
changes the vane angle. No subsequent control is
performed. The remote controller display doesn't change.

Control details
1.1 Drain pump control
The drain pump turns ON for the specified amount of time when
any of the following conditions is met (regardless of whether the
compressor is ON or OFF)
1 ON for 3 minutes after the operation mode is switched from COOL
or DRY to another operation mode (HEAT mode).
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 intake temperature [ -10deg, 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.)
1.2 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 met:
1 Drain pump is ON.
2
Indoor piping (liquid piping) temperature - indoor intake temperature [ -10deg
(except during defrosting)
3 Indoor piping (liquid piping) temperature or indoor intake temperature
is at the short or open level temperature.
4 Every hour after the drain pump has been switched from ON to OFF.
Remarks
✻1 Whether the unit has a swing
function is listed in the
function/control specifications.
✻ See the function/control
specifications for the vane motor
type.
✻ Unit is under “heating,” “hot adjustment,”
and “Compressor ON” mode, and is
set to “Low,” the intake temperature
