Blue LED: level indication
LED on = level sensor activated
Red LED: BMS operation
- LED on = event defined by the BMS condition is in progress
- LED off = no BMS event in progress
Green LED: pump operation
- LED on = pump running
- LED off = pump off
NOTICE
 If the enclosure has been opened, take care not to
pinch or pull the cable when refitting the front panel.

10.3 LEARNING LOOPS

The management of the delay time in "Automatic" mode is not ad-
justable. It is calculated using a learning loop that averages the last 5
switch-ons.
In-
An increasing delay time is the symptom of a drop in output flow and
may therefore indicate a fault in the discharge installation (clogging, etc.).

11. GUARANTEE

ject to correct installation, use and maintenance of the unit.
