  6. Panel Connection Input and Output Signal Display the Operation Status/ Control the Operation

  7. Features • Graphical LCD Display • Network to link up the Chiller (Chiller BUS) • Password Protected Advance Parameter Setting • Individual Cool Set Temperature and Heat Set Temperature • Status Display (Panel Temperature, Defrost and Discharge Sensor Temperature, erasable compressor run time) • Manual Defrost Selection • Real Time Clock (RTC) and Date Display • 7 days Programmable timer ( 2 ON/OFF timer) • 47 Types of Alarm Display • 20 erasable Alarm Memories • Screen Saver Display

  8. Installation Of Chiller Panel Controller • Supply +12 Vdc as a power source to the device • Maximum current is 200 mA • Isolated all the low voltage wiring (communication bus, etc) from high voltage power supply wiring • 4 way wires (CN8 – CN8) provides the easiest solution to communicate between panel and chiller main board

  9. Wiring Connection Connect the Communication Between main board (MC 01) to the Panel with CN8-CN8

  23. Alarm Menu Content in Alarm Menu If there is no existing alarms, “show alarms” will display the old record alarm ALARM MENU Show Alarm Erase All Alarms Keep Up to 20 Alarms Erase the records of histories alarms

  24. Alarm Menu Status Of Mini Chiller IF unit detected having faulty Alarm will trigger & Unit will be turn OFF After the alarms have been dissolved Unit can only be turn ON via Manual Reset (Off & On the power supply of Unit) or Auto Reset (Unit will restart all 3 minutes) Setting of reset type can be done in the “Alarm & Contact” in “SET PARAMETER”

  25. Display Menu Display the temp of Discharge sensor for monitoring the high temperature of compressor discharge DISPLAY MENU Defrost Sensor Discharge Sensor Comp run Time Display the temp of defrost sensor for Condensing Unit Compressor Run time of the Chiller

  26. Application with two compressors Partial load capabilities • Two separate refrigerant circuit • Two compressors • 0-50-100% of rated capacity • Improve the reliability and energy efficiency of chiller • If one compressor is spoiled, the unit still can run with one compressor

  27. How chiller works with single compressor? Difference temp of the set-temp and sensed temp (temp of water return/leaving) Temperature Comp on Cooling Set-temp. + Differential Cooling Set-Temp. Comp off

  28. Example Cooling Set-Temp = 12 oC Differential = 3 oC Cooling Set-temp. + Differential. = 15 oC Temperature Comp on 15 oC 12 oC Comp off

  29. How chiller works two compressors? Temperature Comp 2 On Cooling Set temp. + Differential Comp 1 On Cooling Set temp. + ½ Differential Comp 2 Off Cooling Set Temp. Comp off

  30. Example Cooling Set-Temp = 12 oC Differential = 3 oC Room Temperature Comp 2 On (12 +3) = 15.0 oC Comp 1 On (12 + ½ * 3) = 13.5 oC Comp 2 Off 12.0 oC Comp off
