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
