Frequently Asked Questions
What is the typical operating voltage range?
The device operates on a voltage range of 9.6 - 17 VDC or 21.3 - 31.5 VDC.
How are electrical issues reported?
Operational errors can be read out in the software, and error codes or LEDs provide indicators.
What cooling methods are available for different applications?
Cooling requirements include Static (S), Oil (O), and Fan (F) cooling options depending on the application type (LBP/MBP/HBP).
Can the unit adjust its speed based on demand?
Yes, in Adaptive Energy Optimizing (AEO) mode, the compressor will always adapt its speed to the actual cooling demand.
