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

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
