2. Product features
The central controller is capable of controlling up to 50*1 air conditioner units. It supports the following functions.
(*1: The maximum number of connectible units depends on the indoor unit models.)
[1] User operation functions
(1) Operation
1. Most of the functions of the local remote controllers are supported by the central controller.
The central controller can turn on or off the indoor units in specific groups, display the room temperature for
each indoor unit group, change the operation mode of the indoor units (COOL, DRY, FAN, AUTO and HEAT)
and of the ventilation units (HEAT RECOVERY, BY-PASS, AUTO) as well as change the fan speed, air flow
direction (4 directions and swing), ventilation mode (OFF, LOW speed, or HIGH speed), TIMER MODE, and
temperature setting.
(Refer to section "5-7 User setting".)
2. Access to specific functions of the local remote controller, such as ON/OFF operation, mode selection, temperature setting, and filter sign reset can be prohibited.
3. Group setting
Operation settings can be made for the entire groups or for each individual group.
(2) Weekly Schedule
1. The weekly schedule allows four different patterns of schedule to be set for each group. (P1-P4)
Three of the four patterns (P1, P2, P3) are used to set the ON/OFF schedule, and the other one (P4) is used to
prohibit the operation from the local remote controller. The ON/OFF schedule patterns (P1, P2, P3) can be used in
combination with the operation prohibition function (P4) to set the schedule within the same day. By setting the
schedule for each day of the week by using the four schedule patterns in combination, a weekly setting can be
made for each group.
2. For each day, three ON times and three OFF times, or three prohibition times and three permission times can be
set. It is possible to set only the ON times (prohibition times only) or only the OFF times (permission times only).
3. Easy setting
Daily operation schedule and weekly schedules (P1-P4) of a group can be copied to the settings for other
groups.
(3) Operation status monitoring
1. The ON, OFF, or MALFUNCTION status of each unit or the group can be monitored.
2. Either the group numbers or the first three characters of group names that are controlled by the central controller
can be displayed. The address of all units can be displayed altogether.
3. While all groups are displayed on the screen, the group that is marked with the
OFF.
symbol can be turned ON or
(4) Malfunction monitoring
1. The unit in error, error code, the address of the unit that detected the unit in error will appear on the "Malfunction
monitor" screen.
2. Pressing the reset key stops all the units in the same group or in the same refrigerant system as the unit in error,
and resets the error.
[2] System configuration setup and maintenance
(1) System configuration setup
1. Indoor units, local remote controllers, and lower-level system remote controllers can be registered in the same
group. OA processing or LOSSNAY units can also be registered.
–2–
WT03945X02_En_P01-35

07.3.23, 8:12 PM
2. Each group can be specified by its name.
(Alphanumerical characters can be used for the group name.)
3. Group names can be copied to the settings for the other groups.
4. The group configuration settings and the group names can be set as long as power is supplied to the central
controller, even if indoor units have not been connected.
5. When the system configuration was changed, the system configuration data on the central controller can be
erased all at once if necessary.
(2) Refrigerant system monitoring
The addresses of all the units (indoor, outdoor, etc.) in each refrigerant system can be displayed on this screen.
This information is useful for checking the address setting, transmission line connection, and power supply connection.
(3) Interlocked operation setting
Make this setting to perform an interlocked operation of one or more of the indoor units and a ventilation unit. The
interlocked ventilation unit will go into operation when one of the indoor units that is interlocked with it goes into
operation.
(4) Malfunction log
1. The log of the central controller will be kept for the last 64 errors.
2. Information about the date/time of error occurrence, address of the error-source unit, error code, and the address
of the unit that detected the error will be displayed on the screen.
3. The log of the central controller and indoor units can be deleted all at once with the reset button.
[3] Miscellaneous
(1) Entire-system status lamp (Operation/Stop)
Displays the status of the entire system (Normal operation, all OFF, and malfunction status are indicated with a lit,
unlit, blinking lamp respectively).
(2) Collective ON/OFF switch
This switch turns all of the units in the system ON or OFF at once.
(3) Power supply wiring
Power to the central controller is supplied from the PAC-SC50KUA unit through the M-NET transmission line of DC
power line. The length of the DC power line between the PAC-SC50KUA power supply unit and the central controller must not exceed 10 m.
The central controller can be connected to anywhere on the M-NET transmission line. (M-NET transmission line is
a central control line that is connected to the TB7 on the outdoor unit.)

(2) Set-back values and setting temperature setting
• Setting the set-back values and setting temperature can be performed only when selecting either "SET BACK" or
"SET TEMP" on the user setting screen in the initial setting mode.
• Set-back operation
Set-back operation is a method which reduces the air conditioner running cost by controlling the operation with
specified time band for lowered load. In other words the unit operates at a few degrees higher for cooling and a few
degrees lower for heating in the specified time band.
<<EXAMPLE>> When the reference temperature is 24˚C / 75˚F and the set-back value is set to 2˚C / 4˚F.
• Cooling operation: 24˚C+2˚C=26˚C / 75˚F+4˚F=79˚F
• Heating operation: 24˚C-2˚C=22˚C / 75˚F-4˚F=71˚F
• Setting temperature operation
This operation sets the temperature when timer ON is set to a predesignated temperature regardless of the
operation mode.
