2 . Product Features

The central controller is capable of controlling up to 50 air conditioner units. It supports the following operating

function.

[ 1 ] User operating function

(1) Operation

1. Virtually almost functions operated by local remote controller are supported.

The central controller can be used to control the indoor units in specific group ON or OFF, select the operating

mode (COOL, DRY, FAN, AUTO and HEAT) for the indoor unit or HEAT RECOVERY, BY-PASS, AUTO for the

ventilation unit), select the fan speed, select the air direction (4 direction and swing operation), select the ventil-

ation mode (OFF, LOW speed, or HIGH speed), select TIMER MODE and select the temperature setting.

In addition, room temperature can be displayed at the unit of each group upon request.

(See 5-5 "User setting")

2. Local remote control operation can be prohibited for specific functions.

Access to specific control functions, such as ON/OFF operation, mode selection ,temperature setting and filter

sign reset operation can be prohibited for the local remote controls collectively or per group.

3. Collectively setting

Operation setting can be performs collectively or per group.

(2) Weekly Schedule

1. The weekly schedule enables four different schedule patterns to be set weekly per group. (P1-P4)

Of these, three patterns are to set ON/OFF schedule and remaining one pattern is to set the pattern to prohibit op-

eration of the local remote controller.

Four patterns (daily patterns) mentioned above enable the setting of individual schedule times for every group.

2. The respective daily patterns enable the setting of three different ON times (three prohibition times) and three

different OFF times (three permission times).

In addition, it is possible to set ON time only (prohibition time only) and OFF time only (permission time only).

3. Easy setting

Daily operation patterns and weekly schedules for one group can easily be copied to the other groups.

4. Timer automatic recovery operation when recovering from a power down is supported.

(3) Operating status monitor

1. ON/OFF/MALFUNCTION status can be monitored by group or by unit.

2. The groups managed by the central controller may be displayed all together by group number or group name

(first three characters). Collective display of all unit address is also supported.

3. When displaying all groups at once, individual groups can be turned ON or OFF by designating them by the

indicator .

(4) Malfunction monitor

1. The unit address where the malfunction occurred, the error code and address of the unit that detected

the malfunction are displayed on the malfunction monitor screen.

2. Pressing the reset key stops all the units connected to the same group, refrigerant system or linked group to the

unit where the malfunction occurred, all of these are reset.

-2-

[ 2 ] System configuration setup and maintenance function

(1) Setup for system configuration

1. Registration can be made for the indoor units, local remote controllers and slave system controllers in the same

group.

And also registration can be made for the ventilation such as OA processing unit.

2. Group name may be specified. ( Names may include alphanumeric characters.)

3. Group name may be copied.

4. Setting of group configuration and specifying the group name may be performed as long as power is being supplied

to the central controller. This mean that setting can be performed before the central controller is installed at

the site, before installation of individual units is completed or while the power supply to some units is cut off.

5. System configuration data setting in the central controller can be deleted at once if necessary when replacing cir-

cuits wired board, etc.

(2) Refrigerant system monitor

All unit address (indoor, outdoor, etc.) can be displayed for individual refrigerant system on the refrigerant system

monitor screen. This information is useful for checking the installation, such as address setting, transmission line

connection and power supply connection.

(3) Interlocked group setting

Setting can be performed for indoor units interlocked with a ventilation unit.

If even one of the indoor units interlocked with ventilation have started to operate, the ventilation will be activated.

(4) Malfunction log monitor

1. A log of the last 64 malfunction massage, in the order in which they occurred, can be monitored.

2. The data and time the malfunction occurred, the address of unit where it occurred, the error code and the ad-

dress of unit that detected the malfunction are displayed.

3. All malfunction logged in the memory of the central controller and indoor unit can be reset at once.

[ 3 ] Other

(1) Overall statues display lamp

Displays normal operation/all OFF/malfunction status for the entire system.

(Normal operation/all OFF/malfunction status is indicated by the lamp being lit, not lit or blinking respectively)

(2) Collective ON/OFF switch

This switch allows turning all of the unit in the system ON or OFF at once.

(3) Power supply wiring

The central controller is supplied power from the PAC-SC50KUA Power Supply Unit via the M-NET transmission line and

DC power line. The DC power between the PAC-SC50KUA Power Supply Unit and the central controller should be 10m

or less. The central controller allows to be connected to M-NET transmission line at any position. (M-NET transmission

line is the central control line which connects TB7 terminal of the outdoor unit)

(4) M-NET transmission line

The combined maximum distance between the outdoor units and the central controller, and between the outdoor units

and farthest indoor units connected to the same refrigerant system or their remote controller, may be extended up

500 meters.

Therefore, even if the total distance is made longer by installing the outdoor units all in row, there will be no problem

so long as the above maximum total distance limitation is not exceeded.

(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 op-

eration mode.
