3-2-4 I-Wert X.XX
I-factor of the combined control for the ECO compressors
Example: for control error of 1 K with an I-Wert of 0.5, the I-component
changes with 0.05 V per cycle time (1 second) of the controller
Attention!
The set value is reduced by a factor of 10!

5.8.2 Control by a VS 3015 C and a separate pack controller
Introduction
The ECO compressors are controlled via the VS 3015 C pack controller
and a separate
pack controller (e.g.
VS 3010) that receive an enable signal from the VS 3015 C pack controller. The VS 3015 C outputs the enable
signal at the relay output 10 (terminals 3/4).
Requirements
•
Second VS 3010 pack controller
•
The parameter "
ECO-Mode
" (menu 3-2-4) must be set to YES.
•
The parameter "
ECO-Compressor
" (menu 3-2-4) must be set to NO.
