Terminology
Term Explanation
ARAVF Automatic restart after voltage failure. See Elektronikon regulator.
Compressor
elements 1/2
Element 1 is the low-pressure compressor element; element 2 is the high-pressure
compressor element.
The regulator does not accept illogical settings, e.g. if the warning level is programmed
at 205 ˚C/401 ˚F, the minimum limit for the shut-down level changes to 206 ˚C/402 ˚F.
The recommended difference between the warning level and shut-down level is 10
˚C/18 ˚F.
