Frequently Asked Questions - EKDICMPAL DAIKIN

What is the Daikin EKDICMPAL intelligent Chiller Manager used for?

The EKDICMPAL is an Intelligent Chiller Manager (iCM) that centralizes control and monitoring of chiller plant systems, including chillers, pumps, valves, and sensors. It supports up to 8 chillers and integrates with BMS via BACnet or Modbus.

How do I connect the iCM to Daikin On Site cloud service?

Ensure the controller has internet connectivity via the built-in 3G router. On the HMI, navigate to ConfigMode > SystemSetting > Network > DaikinOnSite and set it to Enable. Then configure the IP settings under MainController.

What is the maximum number of chillers that can be registered?

Up to 8 chillers can be registered. Each chiller can be associated with evaporator and condenser shut-off valves. Registration is done under ConfigMode > DeviceRegistration > Chiller.

How do I set the system to Config Mode?

From the Main Menu, select ConfigMode. Ensure the system is OFF (system ON/OFF must be OFF). Then set ConfigMode to ON. This allows equipment registration, trial runs, and configuration changes.

What type of sensors are supported for temperature measurement?

The iCM supports NTC10K and 4-20mA temperature sensors. Chilled water sensors are NTC10K (supplied). For other sensors, the port type can be configured in DeviceConfig > SensorConfig.

How do I perform a trial run for connected equipment?

After putting the system in Config Mode, go to ConfigMode > TrialRun. Select I/O Trial Run or Chiller Trial Run. Follow the on-screen prompts to send commands and verify responses.

How can I reset an alarm on the iCM?

Press the Alarm Button on the HMI to view active alarms. Navigate to Alarming > Alarm List. Select the alarm and choose Reset Alarm. Some alarms may require clearing the cause first.

What is the password for accessing hidden menus?

The default password is 0000 (four zeros). Enter it in the Password menu from the Main Menu. If forgotten, contact Daikin support. The system logs out automatically after 10 minutes of inactivity.

Can the iCM control variable frequency drives (VFD) for pumps?

Yes. In DeviceCtrlParam > PrimaryPump Ctrl, set PumpType to VFD. Then configure PI parameters, setpoint, and staging thresholds for differential pressure control.

How do I back up the configuration settings?

Insert an SD card into the controller. From ConfigMode > Backup/Restore, select Backup to save configuration data. To restore, use the same menu and select Restore.

3.3. I/O Mapping

The mapping of I/O's on the main controller and the extension I/O modules is predefined. You can find the full list of I/O mapping in the appendix to this document (18 APPENDIX - I/O Mapping)

3.4. Networks

There are three communication Networks in the iCM:

Modbus® / RS485 for the integration of chiller data into the iCM controller
☐ BACnet / IP or Modbus®RTU / RS485 for the connection between the iCM controller and a general BAS/BMS
☐ IP Service interface over Ethernet for communication with Daikin on Site through Internet connection.

3.4.1. Modbus® / RS485 (Chiller Network)

The data residing in the chillers are integrated into the iCM controller using Modbus® / RS485. The set of Modbus® data point varies slightly with the chiller type. iCM has Modbus data map for Daikin global standard chillers pre-included, allowing for easy Modbus / RS485 connection through just simple configuration. (19 APPENDIX – Compatibility List)

In the appendix of this document you will find an overview of which Modbus® points that are integrated into the iCM (20 APPENDIX – Integrated Modbus Points)

3.4.2. BACnet

For general integration of the iCM and a BAS/BMS workstation, BACnet is available.

You can find the full list of BACnet points for iCM in the appendix to this document (16 APPENDIX – BACnet Integration Data (Main Controller)) Modbus®

4. Electrical Installation

4.1. General specifications

All electrical connections to the unit must be carried out in compliance with laws and regulations in force.

All installation, management and maintenance activities must be carried out by qualified personnel.

Refer to the specific wiring diagram for the unit you have bought. Should the wiring diagram not be on the control panel or should it have been lost, please contact your manufacturer representative, who will send you a copy.

In case of discrepancy between wiring diagram and electrical panel/cables, please contact the manufacturer representative.

Only use copper conductors. Failure to use copper conductors could result in overheating or corrosion at connection points and could damage the control panel.

To avoid interference, all control wires must be connected separately from the power cables. Use different electrical passage ducts for this purpose.

Particular care must be taken when realizing wire connections to the switchbox; if not properly sealed, cable entries may allow ingress of water into the switchbox which may cause damage to the equipment inside.

Before any installation and connection works, the unit must be switched off and secured.

This product complies with EMC standards for industrial environments. Therefore it is not intended for use in residential areas, e.g. installations where the product is connected to a low voltage public distribution system. Should this product need to be connected to a low voltage public distribution system, specific additional measures will have to be taken to avoid interference with other sensitive equipment.

4.2. Operator's responsibility

It is essential that the operator is appropriately trained and becomes familiar with the system before operating the panel. In addition to reading this manual, the operator must study the databook for functional overview and the wiring diagram in order to understand start-up sequence, operation, management of the peripherals connected to the control panel.

5. Mechanical Installation

5.1. Control Panel installation

Control panel can be installed free standing taking care of the following minimum clearance requirements:

Figure 3 Minimum Clearance Requirements

Cable entry hole is on the bottom side of the panel

For the hanging installation on a wall, please use the brackets shown in the following picture, provided with panel:

Figure 4 Brackets position

NOTE: Weight of different sizes of the panel are shown in Table 2 Electrical panel technical data

5.2. Temperature sensor installation

The sensors should be located on the supply header and on return header.

The location should be chosen such that the water must be well mixed where the temperature is acquired.

The sensor should be mounted such that the cables does not enter from the top (only by side).

The immersion length must be at least 60mm.

Figure 5 Temperature sensor mounting

For more information, please refer to datasheet and installation guide provided with sensor.

5.3. Differential Pressure sensor installation

Differential pressure sensors must be mounted between the inlet and outlet water pipes of the furthest load in the system.

9.1.1. Setting sequence order when using fixed order sequencing

When using fixed order staging method, manual order setting for each chiller needs to be done. 1. From "MainMenu > Setting > DeviceCtrlParam > Chiller Ctrl" screen, follow below steps to reach "Chiller FixedOrder" screen. Here, priority of sequence for manual sequencing can be set with 1 being highest priority.

NOTE: If multiple chillers are set as same priority, the sequence of the chillers will be decided according to operation hours among chillers. So chiller with lower operation hours and higher priority is selected for stage up, whereas chiller with lower priority and higher operation hours for stage down.

15.1.2. Alarms for individual equipment

Alarm for individual equipment, chillers, pumps, valves, cooling towers and sensors, is displayed in the HMI. For each type of equipment, types of errors that are displayed include all or part of the following.

□ Communication error:
Communication with the equipment is lost
□ Device error :
Alarm signal from the equipment is received.
□ Monitoring error:
The equipment did not follow a command from iCM
□ Warning:

Warning signal from the equipment is received

Types of alarms that are displayed for each equipment type and their corresponding error codes are shown in the following table.
