Description
Use at 00 conditions
This function sets the unit to run
in high fan speed regardless
the setting from remote control
switch.
The operation of the indoor
unit fan is stopped in cooling
Thermo-OFF conditions when
using the additional remote
temperature sensor THM-R2AE
(connected to THM4) or the
PC-ARFG-E temperature
sensor.
C8 must be set to 01 to use the
Cd=01 setting.
The indoor unit uses the
PC-ARFG-E temperature
sensor to monitor the room
temperature when the fan is
stopped (heating Thermo-OFF
fan stop sequence).
C8 must be set to 01 to use the
CE=01 setting.
Control by remote temperature
sensor connected to THM4 is
not permitted (use E8 function
in that case).
This function adjusts the angle
of the air outlet louver.
(Changes to the setting of this
function are applied after turning
the power supply off and on again,
or after the automatic louver has
made a full cycle in automatic
mode).
When power supply is restored,
the indoor units controlled by
the wired remote control switch
are turned on regardless of their
ON/OFF status at the time of
the last power cut off.
–
When power supply is restored,
the indoor units controlled by
the wired remote control switch
are turned on automatically
ONLY if they were already ON
at the time of the last power
cut off.
If indoor units were OFF when
power was turned OFF, they
remain in OFF status when
power is restored.
