Features

True Dual Circuits BPHE

The true dual BPHE puts the secondary circuit (water) in contact with 2 primary circuits (refrigerant). So even if one primary circuit is shut off, each secondary channel is still in contact with a primary channel.

Inverter Compressor

Inverter compressor is programmed to run at the optimum speed, which is regulated by the input frequency as it can varies according to the heat load requirement. Inverter advantages are :

• Less start & stop – Frequency regulated compressor resulting in lesser in the sense of start and stop of compressor, which greatly reduces the energy consumption.

• Fast cooling/heating – Inverter compressor has the ability to produce faster cooling/heating capacity at the frequency higher than the dominant capacity frequency.

• Smart loading/unloading – with the integration of built in system algorithm; inverter compressor could control the system’s loading and unloading sophisticatedly.

• Better compressor reliability – Reliability of inverter compressor is always better since there is lesser on/ off of the system especially during low load condition.

Elimination of Water Tank

Inverter system provides constant water temperature band, or much lesser water temperature fluctuation. With this, water tank of the mini chiller system can be eliminated.

Built in Fan Speed

The built in algorithm now controls fan speed, resulting in cost saving since installation of external FSC (Fan speed controller) can be exempted.

Safety Proctection

• High & low pressure switches

• Anti-freeze protection sensor

• Discharge temperature sensor

• Over pressure relief valve

• Water pressure differential switch

• Anti-freeze heater on BPHE

• Compressor, water pump overload protector

Anti Corrosion Heat Exchanger

Gold aluminum fin is offered as standard material of the condenser heat exchanger of this series of chiller.

Modular Installation

A network up to 50chillers in a system is possible. Control on the operation of the chillers will be done through the microprocessor controller. The external water piping connection can be made either from the left or right

side of the unit.

Chiller Panel Controller

1. Safety Consideration

Only specially trained and technicians and installers are authorized to install and service this equipment.

1.1 General Installation Recommendations

• Only supply DC voltage (9-17V, typically 12V, maximum current 200mA) as a power source to the device.

• Input contact voltage supply should limit to 12VDC or 24VAC.

• Isolated all the low voltage wiring (communication bus, etc) from high voltage power supply

wiring.

2. General Description

2.1 General

The chiller panel controller is designed to control the chiller operation. This device allows the user to have customized control for each connected unit.

2.2 Features The requirements of user friendly and easy to use have been taken into account in designing this

chiller panel controller. It can do the task as follow:

• Whole system configuration

• Unique parameter settings

• Operation status display

• Tracing fault record (easy in hardware troubleshooting)

The display is shown in an 8-lines graphical LCD display. There are 8 dedicated keys available in the panel,

• Menu selection

• Navigation on the screen

• Modification of the selected value

During first start-up, the panel will have a default configuration (timer schedule, set point, miscellaneous settings, etc). User can do the changes on that particular configuration later.

2.3 Panel Position

The chiller panel controller can be installed anywhere, as long as it is easy to accessed by authorized personnel.

The requirements of installation are:

• Avoid exposure to shocks

• Avoid any source of electromagnetic pollution

• Avoid installation on uneven vertical surface

2.4 Operation Environmetal Condition

• Temperature:

-10°C to 47°C operating temperature

-20°C to 85°C storage temperature

• Relative Humidity: 0 to 95% non-condensing

4. Installation

4.1 Chiller Bus

Chiller Network

Chiller panel needs to be energized with +12Vdc. The 5 way wires that provided is once on the easiest solution to establish a communication between the panel and chiller main board (CN8-JP13). If the 5-way wires socket has been occupied in main board, just using 2 insulation wired are needed to establish a communication between panel and chiller main board.

Chiller panel can support maximum up to 50 units of chiller. In the chiller network, duplication of main board unit address is not allowed. Each chiller main board should have their unique unit address (0-50). For first time running, user need to assign a unique unit address to each main board in the chiller network. User should follow the procedure below:

• Only power ON one main board at once time. Make sure not others main boards are energized.

• By using the panel connected to the main board.

Summary Pages Main Menu Setting Menu

key in "0001" as pas sw ord

• Key in unique unit address and press ENTER to execute.

• De-energized the main board and repeat the procedures again all the main boards have been

assigned a unique unit address.

IMPORTANT : Do not assign a same unit address to more than one chiller main board.

RECOMMENDATION : Please select a coherant model (G1 Model) to all the chiller main boards in the same network.

Supported up to 50 units of Chiller

Chiller Panel 0 Chiller Panel 1 (Master) (Slave)

5 way wire (CN8) Chiller Communication bus

Chiller 0 Chiller 1 Chiller 2

4.2 Others Configuration

• JH2 in chiller panel should let it open (put the jumper header on one pin only) all the time

unless user need to do CMOS reset to that particular panel.

• JH3 should let it open (put the jumper header on one pin only) all the time as well.

• Remember to put in the coin cell battery on the panel. Without the backup battery, the panel will

always reset the time to 12:00am, 1st Jan 2000.

4.3 Installation of Chiller Panel Controller

• Disconnect the unit and ensure no others unit energy source that supplies the panel.

• Open the rear panel of the Chiller Panel (insert a ‘flat-head’ screwdriver in the top joint of main casing with rear panel to open the real panel).

• Pass the necessary wires of the panel across the large opening in the rear panel. Place the rear panel flat support against the wall and make marks on the wall through the four installation holes (inner and outer).

• Drill four appropriate holes in the marked places.

• Attach the rear panel to the wall and put on the screws on it. Ensure that all cables are passed

through the hole of the rear panel.

• Connect the wires to the corresponding terminal according to the wiring bus network. The

power supply and communication wires must be correctly connected to ensure that the panel works.

• Close the chiller panel (ensure the bottom joint is aligned for the casing, then complete others joint part. Ensure that the contacts at the back of the panel are aligned with each others).

6.1 Starting

Chiller panel can be set as Master or Slave panel unit. When the Panel ID is set to ‘0’, it acts like a Master panel, whereas it is Slave panel if Panel ID is set to others number (1-50).

Chiller panel can control the Chiller if both ID no. (Panel ID and Chiller ID) are same.

For example: Panel ID 1 can only control Chiller ID 1

Master Panel can choose to control each Chiller or control all Chiller at once in the network.

For example : Panel ID 0 (master) can control Chiller ID 0 / ID 1/ ID 32 .... or all Chillers at once.

Panel ID can be set in Set Panel ID in Settings Menu.
