7-1. Operation Functions

Emergency operation
Emergency operation is available when the remote
controller malfunctions, has been lost, or otherwise
cannot be used.
To operate the system, press the OPERATION button,
which is also used as the receiver, below the unit display.
Each time this button is pressed, the OPERATION lamp
changes color to indicate the type of operation. Select the
desired type of operation.
COOL HEAT
(GREEN) (RED)
• The set temperature is 2 °C below the detected room
temperature in the case of cooling operation, and 2 °C
above the room temperature in the case of heating
operation. The flap and fan speed settings are AUTO.
AUTO cooling/heating operation
Selecting the operation mode
• When AUTO mode is selected, the microprocessor calculates
the difference between the set temperature and the room
temperature, and automatically switches to Cooling or
Heating mode.
Room temp. Set temp.
Room temp. Set temp.
• As shown by the example in the figure below, with AUTO
cooling/heating operation, the mode changes between
Heating and Cooling mode according to changes in the
relationship between the current room temperature and the
set temperature.
Example

SENSOR DRY
During DRY operation, the system adjusts the room
temperature and fan speed according to the conditions in the
room, in order to maintain a comfortable room environment.
SENSOR DRY operation
• DRY operation is as shown in the figure below.

Conditions are monitored at all
times when the room temperature
is below 15 °C.
DRY A
The compressor operation frequency varies.
The indoor fan operates with 1/f fluctuation.
DRY B
The compressor operates at a low operating frequency.
The indoor fan operates with 1/f fluctuation.
Monitor
• Monitoring operation takes place when the room temperature
is below 15 °C, or more than 3 °C below the set temperature.
• When the monitoring range is entered, the compressor stops,
and the indoor fan operates with 1/f fluctuation.
PAM- control
• In order to further improve inverter performance, control is
switched between PWM control at low operation speeds, and
PAM control at high operation speeds, making the most
effective use of power.
