Operation and function
ATTENTION!
Damage by overheating!
The manual mode > 0 % of the power stages in a system
electrically connected, but not hydraulically filled can lead to
damage caused by overheating!
Î
Make sure the hydraulic system is filled and ready
for operation.
An operating mode can be selected for each stage of the power unit (electric
immersion heaters). The following options are available:
Auto = Stage is in automatic mode
0 % = Stage is switched off
100 % = Stage is switched on at 100 %
The power of the modulating stage 1 can be set to the manual mode in steps of 10 %.
Note:
After service and maintenance work, the operating mode must be set back
to Auto. Normal operation is not possible in manual mode.
4.12 User code
