1.5 Description of Functions1.5.1 Individual Screen, all Screen, Zone Screen

This controller can perform operations in the individual screen, all screen, or zone screen.Individual screenThe individual screen is used when performing group operations.All screen The all screen is used when performing operations for all units at once.Zone screenThe zone screen is used when performing zone operations.

1.5.2 Basic functions

1.5.3 Zone control functions

1.5.4 Cool/Heat changeover and eligibility setting

Note:Refer to the next page for the selection of cool/heat mode (eligibility for cool/heat changeover).

Descriptions of outline

Individual/Zone control Up to 64 groups (Max. 128 units and max. 16 units per group) of indoor units and HRV units can be controlled by individually or by zone.

Unified ON/OFF ON/OFF can be set for each zone, and can be controlled simultaneously for entire system by push button or by contact signal from outside.

Malfunction code display The status of each group is always displayed, such as ON/OFF, error, etc. If the error occurs, it displays the contents of error by malfunction code through the self-diagnosis function.

Connection of unification adaptor for computerized control

By connecting the unification adaptor for computerized control (option), it can be linked with the central monitoring panel and etc. by contact signal, which enables you to operate ON/OFF simultaneously or monitor the operating status.

Remote control acceptance/rejection It is possible to restrict the function of local remote controller.(Only ON operation rejection, or ON/OFF operation rejection)

2 central controllers By connecting two central remote controllers, the same air-conditioner can be controlled from 2 locations (By tenant or administration office.)


Zone control The zone function is a function to control one or more group of air-conditioner, and the operation setting such as ON/OFF etc. can be made by zone.

Up to 64 zones Up to 64 zones (64 groups for each zone) can be set. However, the group setting spreading over the plural zone cannot be set.

Zone register

When the power is supplied first time, each group is registered in each respective zone. If you can simply register the several groups in the same zone by switch, so that you can have simultaneous operation of the units in that zone immediately. (The operation of temperature setting and etc. is also controlled by zone simultaneously.)

Zone setting By adding the zone setting function (Zone “0”) from the central remote controller, you can set the same setting for all the zone registered by single operation.

ON/OFF control of zone

For example, if there are three groups in one room and if you register these three groups as one zone, you can operate these three groups simultaneously by single operation (ON/OFF, temperature setting etc.).You still can operate each group individually by local remote controller.

Maintaining zone setting Even if the power is turned off, the zone configurations set are maintained semi-permanently. (saved in non-volatile memory)

Cool/Heat changeover by zone The cool/heat changeover can be made by zone. However, it is required to have a master group for Cool/Heat changeover in that zone.

Batch operation The same setup is possible at one operation to all the groups registered on the "All" screen.

No local remote controllerEven if there is no local remote controller, you can still perform the same operation. There is no problem even if no remote controller is connected. (However, in this case, each one air-conditioner consists of one group.)

Combination with other controllers You can also combine with a unified ON/OFF controller and a schedule timer. (Refer to the system configuration for details.)

Connection to central monitoring panel You can also combine with an Interface for use in BACnet and a data station in order to connect to the central monitoring panel. A parallel interface can also be connected.


Possible controlThe operation mode of the outdoor unit can be changed by the local remote controller or by the central remote controller. (For test operation, change setting of cool/heat selector switch of the outdoor unit.)

Remote controller acceptance/rejection You can set the remote controller acceptance/rejection on the central remote controller by the local remote controller.

"NOT AVAILABLE" DISPLAY(NO FUNCTION DISPLAY)

If a function is not available in the indoor unit even if the button is pressed, "NOT AVAILABLE" is may be displayed for a few seconds.

1.5.5 Control with Two Central Remote ControllersThe central remote control equipment is newly designed to "B" type, which has been added with a new control function for 2 central remote controllers. However, be sure that the relation between Main/Sub of the central remote controller is different from those of local remote controllers.

Note:Be sure that if timer No. is registered by the sub central remote controller, [Timer mode acceptance for local remote controller (mode no. 8,9,18, and 19)] for the same units set by the Main remote controller becomes meaningless (operates when time comes.).

<Explanation of the above figure>If you operate the central remote controller in the sequence of and , the indoor unit is set for cooling / temperature setting 24°C.However, the display of zone setting of the master remote controller remains at heating / temperature setting at 27°C.

<Cautions>Operation code cannot be set by the sub central remote controller.Combined zone operation can only be set by zone registration of the main central remote controller.Both main and sub central remote controller are operated by a Last priority command for the functions other than the above.However, the display on the central remote controller cannot be changed by each other. (On the display for the group, you can monitor the present operation status.)

Control Devices

1.7 Initial SettingSetting (1) through (3) are initialized when power is turned ON, therefore complete settings BEFORE activating the power. (The positions of connectors and switches used for settings in this section are shown in Fig. 1.)

(1) Connector for setting master controller (X1A) (Provided with connector at factory set)• When using only 1 central remote controller, do not disconnect the connector for setting master controller. (Use the

unit with the connector in the state in which it was delivered.)• When using multiple central remote controllers, or using the central remote controller in conjunction with the optional

controllers for centralized control, makes settings as indicated in the below table.

(Remove this connector when using this controller in conjunction with power consumption counting unit, parallel interface, and data station.)

(2) Address settingTwo central remote controllers can be used as shown in “SYSTEM CONFIGURATION” to control anywhere up to a max. 128 groups of indoor units. In this case, group address must be set. This is done with the switch for setting each address (SS3).

(3) MAIN/SUB changeover switch settingWith two central remote controllers, centralized control (indoor units) is possible from different locations. In this kind of set-up, it is necessary to set the MAIN/SUB changeover switch.

One of the two central remote controllers (1) · (2) is set to “MAIN” while the other is set to “SUB”

(4) Setting of the sequential operation functionThe central remote controller is equipped with a sequential operation function that sequentially turns indoor units on in 2-second intervals during unified operation. (Sequential operation is factory set to “ON.”) To switch sequential operation ON or OFF, set as follows.

Note:The sequential operation function is designed to reduce the load on the power supply equipment, but does not guarantee that compressors will not be started simultaneously. You cannot therefore count on a capacity reduction effect by power supply equipment breaker selection.

setting of the Mode No. to "02" and the Switch Setting No. to "0".Setting Contents and Setting No.

Items indicated by boldface represent the factory set for the No. of Switch Setting.Do not make setting of any items not listed in the table above.

Refresh functionThis function is used to automatically send "OPERATION MODE" and "TEMPERATURE SETTING" from the central control system while in operation. In order to disable the refresh function, set the "No. of Switch Setting" to "0".

Restriction items from sub central remote controller while in double central control functionWhile in double central control function, no settings of zone interlock and operation code can be made from the sub central remote controller. In order to disable the refresh function from the sub central remote controller, set the "No. of Switch Setting" to "0".

Setting of area designation for forced OFF• In order to stop all indoor units within the scope of control as a single unit using the entry of T1 and T2, set the "No.

of Switch Setting" to "1".• In order to stop all indoor units within the scope of control with forced thermostat OFF using the entry of T1 and T2,

set the "No. of Switch Setting" to "2". With this parameter set to "2", no forced stop can be made on any indoor unit.

Control Devices

1.10 Refreshed OperationRefreshed operation is the function to transmit setting of "Temperature control", "Temperature setting" automatically from DCS302CA61."Refreshed operation" is "ON" when shipped from the factory.

Factory Setting

It depends on the setting of outdoor systems that an indoor unit setting is "Temperature control" or "Temperature setting"In case of Refreshed operation is "ON"• When setting is changed by DCS302CA61, it operates by this setting from the next operation.

If it sets up with 26 °C in cooling by DCS302CA61, "in the case of the equipment which has not carried out zone setting by a central remote controller, it operates from next with the mode of operation and preset temperature which were set up on the individual screen." In the case of the equipment which carried out zone setting, it operates from next with the mode of operation and preset temperature which were set up on the zone screen.(Priority is given over the mode of operation and preset temperature which were set up on the zone setting screen). When it sets up all at once, it operates from next with the mode of operation and preset temperature which were set up last time on the individual screen (Equipment which has not carried out zone registration), or the zone screen.If a setting change is made with 26 °C of cooling by a central remote controller on an individual screen (Equipment which has not carried out zone setting)" next operation will also be operated at 26 °C in cooling. (Even if it has changed into heating operation, fan only operation with wired or wireless remote control, it operates at 26 °C in cooling.)

• When zone registration is carried out by Central Remote Controller.It operates from next time with the value set up in the zone.When a zone 1 is set up with 20 °C of heating. (Refer to the system of the following figure.)When controlled by Central Remote Controller, 3 indoor units registered into the zone 1 are operated by 20 °C of heating. Because priority is given to zone setting, even if it sets up 2-02 with 25 °C of heating on an individual screen from Central Remote Controller, 2-02 is operated at 20 °C.

• When there are two or more indoor units in a zone.Because an operating mode depends on the outdoor unit, the operating mode of each indoor unit does not become the same setting.When the outdoor unit system 1 is cooling, the outdoor unit system 2 is heating and it operates by the system of the following figure. Setting of a zone 2 is operated in heating mode, because 2-03, 2-04, and 2-05 do not have a cooling/heating selection right as for 26 °C of cooling, but temperature setting becomes 26 °C.When you unify the operating mode of an indoor unit in the same zone, please set up a zone in the indoor unit of the same outdoor unit system.

Trend display: Allows tracking of transitions between time periods and analysis of trends.

List display: Useful for comparisons between items or checking of detailed information.

Daikin PPD system* generates tenant reports and helps building owners for billing energy.

Operational information of individual indoor units are monitored, allowing for distribution of power consumption at outdoor units.

Displays the operation time periods and cumulative operation duration for individual units. This information can be useful when determining maintenance timing, calculating the number of hours of operation, or drawing up maintenance schedules.

The past operation status of individual units is dis-played in chronological sequence. This basic data is useful for identifying the causes of malfunctions or analysing ways of reducing power consumption.

Metre data on electricity, water, and gas usage for the entire facility can be managed centrally. This elimi-nates the need to check metres manually, and data can be checked in real time whenever necessary.

This provides a record of basic data that is useful for maintenance management and planning. It can be used to check past malfunctions (details, time, etc.), to study countermeasures for the future.

PPD

Perform overview and calculations while at your desk.

*kWh metres to be locally supplied.With the PPD system, data is transferred from indoor units and compared with reference data on the standard power consumption of air conditioning equipment under normal conditions. The results are used to estimate the power consumption of each indoor unit. Note, however, that this measurement method is Daikin original way.

Water tanksThe system can monitor the amount of water stored in the tanks via links with ball taps or water level sensors.

HRVIf the heat exchangers are equip-ped with Daikin's HRV function, the system can turn them on and off as well as changing the venti-lation mode and airflow volume settings via a direct connection.

Sensors

Lighting

Pumps

The system can collect data on temperature, humidity, CO2 density, etc., from sensors.

The system can receive signals from fire alarms and security de-vices.

The system can turn water sup-ply or transfer pumps on and off as well as monitor their opera-tion status. It is also possible to interlock the operation of pumps and chilling units.

Air supply andexhaust fansThe system can turn fans on and off as well as monitor their operation status.

The system can turn lighting on and off as well as monitor its op-eration status.

Central air conditioningsystemWith Daikin chilling units, the system can be connected di-rectly without the need for inter-face units.

Interlock control of lighting or keymanagement systems and air conditioningequipmentThe system can monitor signals that turn off the lights or lock the key management system and shut down the air conditioning equipment in the corresponding area. This prevents wasted electricity if tenants acci-dentally leave the air conditioning on when they leave.

If the data from the sensors indicate the temperature is lower outside than inside, the system can automati-cally shut down the air conditioner and switch on the air intake fans to save electricity.

If a fire alarm signal is received, the system can auto-matically shut down the air conditioning or ventilation equipment in the affected area.

Interface for Use in BACnet®

1. BACnet® Interface

1.1 Outline and Features1. Managing the information on 128 groups of air-conditioners (main units only).2. Up to 256 groups manageable and controllable at once by adding the optional DIII board3. Packaging of air-conditioner objects

* Compatible with BACnet (ANSI / ASHRAE-135)* Compatible with BACnet / IP (ISO16484-5)* Compatible with IEIEJ / p-0003-2000 (plan) (IEIEJ is Institute of Electrical Installation Engineers of Japan)

4. Conforming to European, Oceanian, Safety and EMC rules and regulations.5. JIS-specified basic procedures (RS232C system) readily selective.

1.2 System Outline

Outline of air-conditioner management system control devices

Note :1. A group consists of several indoor units that can be started or stopped simultaneously. As shown in the figure above,

a group consists of several indoor units wired to the same remote controller. For units without a remote controller, each unit is treated as a group.

2. Several groups are registered as a zone with the central remote controller. By pushing 1 button of the central remote controller, all groups within the same zone can be turned on or off simultaneously.

Building management 1 system controls and monitors air-conditioning equipment by the block. A block consists of 1 or more groups (max. 32), and can be set without regard for the zones mentioned above. You must, however, take the following things into consideration.(1) If the air-conditioning mode is switched, as a premise, permission for cool / heat selection for indoor units (by remote

controller or central remote controller) must be designated within the program.(2) Program status is basically monitored by observing the data of a representative unit. The contents which can be

monitored are therefore restricted if the representative unit is designated as an adaptor, etc.Block registration is accomplished through signal transmission from the building control system to the cooler-conditioning system. Because configuration can be changed while receiving power even after operating, maintenance from the maker of the air-conditioning equipment is not required when changing the configuration.

1.7 BACnet Object List

Central control (lower central control disable) and forced system stop are only available for 000, 064, 128, and 192.

(Note 1) The room temperature is measured with the suction air. Since the indoor unit fan stops when the thermostat is disabled or the air conditioner is stopped, or in a special operation such as defrosting, temperature measurement may be affected by the heat exchanger, and may detect and transmit a different temperature from the actual room temperature. For this reason, this value should be considered as a reference for the room temperature.If the building management system manufacturer uses this value for system control (e.g., switching the air-conditioning mode or preset temperature), the manufacturer must take on the whole responsibility.

(Note 2) The air conditioner saves the settings for the temperature, start / stop status, air-conditioning mode, air direction, and air flow rate in the nonvolatile memory each time they are changed, so that the settings will not be lost when a power cut occurs. This nonvolatile memory has a write count limit and may cause a failure if it is written exceeding the limit count.Therefore when the temperature, start / stop status, air-conditioning mode, air direction, and air flow rate of each indoor unit are automatically controlled from the central monitoring panel, be sure that the number of changes for each setting should not exceed 7,000 times per year.

1.10 Functions1.10.1 Air Conditioner Monitor / Control Items

The table below lists the air conditioner items that can be monitored and controlled via the BACnet communication.

Note : 1. The room temperature is measured with the suction air. Since the indoor unit fan stops when the thermostat is

disabled or the air conditioner is stopped, or in a special operation such as defrosting, temperature measurement may be affected by the heat exchanger, and may detect and transmit a different temperature from the actual room temperature.For this reason, this value should be considered as a reference for the room temperature.If the building management system manufacturer uses this value for system control (e.g., switching the air-conditioning mode or preset temperature), the manufacturer must take on the whole responsibility.

2. The air conditioner saves the settings for the temperature, start / stop status, air-conditioning mode, air direction, and air flow rate in the nonvolatile memory each time they are changed, so that the settings will not be lost when a power cut occurs.This nonvolatile memory has a write count limit and may cause a failure if it is written exceeding the limit count.Therefore when the temperature, start / stop status, air-conditioning mode, air direction, and air flow rate of each indoor unit are automatically controlled from the central monitoring panel, be sure that the number of changes for each setting should not exceed 7,000 times per year.

2. Daikin's Interface for Use in BACnet® Agreement

1. JMT — (Joint Matching Test) This is necessary for every independent BMS. The case where a JMT is not necessary is where previously a successful JMT has been carried out and the BMS system has not been updated by software or hardware changes. In the case that the BMS has updated their system by either changes, a following JMT will be required.

2. D-BACS setup-tool — Use of Daikin's D-BACS setup-tool is for confirming the operation / state of connected A / C units & address ID's, prior to connection with the BMS system.

3. BMS Engineering — Creating of the Points. This is NOT to be done by Daikin since it is directly related to the BMS side. The BMS engineer is to carry out the engineering of the Point, however Daikin is responsible for providing the method of how the Points are calculated.

4. Commission — First step, only using Daikin's Interface for use in BACnet®, without connecting BMS. This is to be carried out by Daikin engineering staff with the use of the D-BACS set up tool.

5. Discrepancy of operation of Gateway by BMS — In the case that the BMS maker feels that the Interface for use in BACnet® is not functioning correctly via the BACnet Protocol, a test with the use of Daikin's BACnet Client software can confirm this. (This test is generally not required)
