Remove deposits in the tank.
Check the wiring of the sensor terminals.
Check the correct location of the float connection on the casing.
Check the position of the floats.
Contact after-sales service.
Check pump connection.
Check the wiring of the pump terminals.
Pump connection occurs automatically after a delay.
Thermal break is a symptom of a malfunction that requires a
thorough check.
Check the pump.
Check pump hydraulics.
Check the discharge pipe.
Open the shut-off valve
Check for foreign bodies
Contact after-sales service.
Check for clogged discharge pipe.
Check that the shut-off valve is open.
Check that both pumps are working properly.
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
Smart Control Box is guaranteed for 2 years for parts and labour, sub-
ject to correct installation, use and maintenance of the unit.
