10) Outdoor Unit's Electrical Expansion Valve Control
The electrical expansion valve controls the amount of refrigerant that is allowed to flow in accordance with the
operation status.
The valve is adjusted in accordance with the discharge temperature (TD), the outdoor heat exchanger
temperature sensor (C1), the suction temperature sensor (TS), and the indoor unit's heat exchanger
temperature sensors (E1 and E2).
(1)
Controlled so that the suction temperature (TS) - indoor heat exchanger temperature minimum (E1 and E2)
is between 0 degree and 2 degrees under normal conditions.
There are cases where the aperture opens wider than normal operation if the discharge temperature increases.
(2)
Cooling Mode
Heating Mode
Controlled so that the suction temperature (TS) - outdoor heat exchanger temperature (C1) is between
0 degree and 2 degrees under normal conditions.
There are cases where the aperture opens wider than normal operation if the discharge temperature increases.
11) Demand Control
* The operational current is restricted to either A% or B% as a general indicator during demand input.
•
•
•
A% and B% can be amended in calibrations of 5% between 70% and 100% with the outdoor unit's
maintenance remote controller.
For details on how to amend the parameters, see the chapter on the outdoor maintenance remote
controller, (refer to the section “6-6. Settings Modes : Setting the Outdoor Unit EEPROM”).
A% value amendments: Parameters are amended with item code “1A” (demand 1).
B% value amendments: Parameters are amended with item code “1B” (demand 2).
There is a demand terminal as normal equipment in the outdoor unit.
Demand control can be selected as the following table.
Input current should be DC24V, 10mA
Connecting wiring must be used “shield wiring”.

12) Silent mode
It is avilable to select one of 3 levels of silent mode as listed in the table below.
Outdoor maintenance remote controller: Item code “05” (1: Silent level 1, 2: Silent level 2, 3: Silent level 3)
Attention: Due to decrease of operating noise level, the air conditioner's capacity can be reduced.
Silent mode is ineffective during the test run operation.

There are two types of conditions when entering into a silent mode.
(1) From external input: When short-circuiting the silent pin of the outdoor unit control PCB
(2) From software input: The automatic silent-mode operation can be available in the following procedure.
(However, use the Schedule Timer to set the present time and check for the Schedule Timer from the outdoor
unit.)
Set up silent mode by using the outdoor maintenance remote controller. (For operating procedure, see the Section “6.
OUTDOOR UNIT MAINTENANCE REMOTE CONTROLLER”.)
①
Silent mode setting: Select the Item code “12” by the maintenance remote controller.
②
Parameter: 0 = Normal [No silent mode] (Setting at shipment)
: 1 = Silent mode [Restrict the outdoor unit fan and compressor.]
: 2 = Capacity first rather than silent mode *1 [Stop restricting silent mode in the following condition.]
: 3 = Silent mode timer
: 4 = Timer capacity first rather than silent mode
*1
• Capacity first rather than silent mode (*1)
Condition: If the temperature difference of 2 degrees or more comparing to the set temperature continues for
30 minutes, stop silent-mode operation and return to normal operation. [Capacity first]
Cancellation: When the temperature difference comparing to the set temperature becomes within 1 degree,
the unit will return to silent mode.
• The outdoor unit checks the Schedule Timer every 1 minute.
[Set the address of the Schedule Timer to “1”. (Turn the Setting switch S41 #5-7 to Off.)]
• If the communication with the silent-mode cancellation Schedule Timer is interrupted for 30 minutes, silent-
mode is canceled.

Start time setting: (Setting time at shipment 22:00) → Time: Item code 13/minute: Item code 14
④
Stop time setting: (Setting time at shipment 08:00) → Time: Item code 15/minute: Item code 16
