Frequently Asked Questions
What do I do if my system reports a 'Thermostat failure' error code?
If the NTC thermistor is short-circuit or has no connection, the electronic unit will enter manual mode.
How do I determine if fan cooling (F) is sufficient for my application?
Cooling requirements specify whether suction gas cooling (SG), oil cooling (O), or fan cooling (F) is normally sufficient, indicated by markings in the appropriate fields.
What are the weight specifications for the compressor and electronic unit combined?
The weight is listed as 7.9 kg for the Compressor and 0.27 kg for the Electronic unit.
Are there specific voltage limits I must adhere to when setting up the battery protection?
You can set the Voltage Min value between 32 VDC and 60 VDC, with a default range of 32 VDC to 36 VDC.
