“6.6 Changing operating mode”.
2. After selecting the respective actuator, press the Up or Down
button.
✎ An overview of the preset hydraulic systems can be found in the
chapter “4 Planning and installation”, section “4.10 HDG hyd-
raulic systems”, or in the information booklet “Hydraulic Solu-
tions for the HDG Hydronic”.
All parameters specific to the installed hydraulic system are called
up successively.
✎ For an overview of the hydraulic systems with their hydraulic-
specific parameters, see the chapter “4 Planning and installa-
tion”, section “4.10 HDG hydraulic systems”, or the information
booklet “Hydraulic Solutions for the HDG Hydronic”.
Check that the augers have the correct running direction.
Warning!
Risk of injury from automatically driven components
When activating individual actuators manually, hands and arms
could be crushed.
It is therefore essential to ensure that no inspection or repair work is
being performed when actuators are manually activated, and that
all moving and accessible components are secured.
