Terminology
Term Explanation
ARAVF Automatic restart after voltage failure.See Elektronikon regulator.
Compressor
element 1/2
Element 1 stands for the low-pressure compressor element; element 2 stands for the high-
pressure compressor element.
The regulator does not accept illogical settings, e.g. if the warning level is programmed at
205 ˚C, the minimum limit for the shut-down level changes into 206 ˚C. The recommended
difference between the warning level and shut-down level is 10 ˚C.
