Description

Checking / solution

B26

The bottom DHW temperature sensor is

open

Bad connection

Check whether the sensor is connected

Check the link and the connectors

Check that the sensor has been correctly fitted

Sensor fault

Check the Ohmic value of the sensor

Replace the sensor if necessary

B27

The top DHW temperature sensor is short

circuited

Bad connection

Check whether the sensor is connected

Check the link and the connectors

Check that the sensor has been correctly fitted

Sensor fault

Check the Ohmic value of the sensor

Replace the sensor if necessary

B28

The top DHW temperature sensor is open

Bad connection

Check whether the sensor is connected

Check the link and the connectors

Check that the sensor has been correctly fitted

Sensor fault

Check the Ohmic value of the sensor

Replace the sensor if necessary

B32

The impressed current anode is in open

circuit.

Check that the connection cable between the SCU PCB and the

anode is not severed

Check that the anode is not broken

Check that the DHW tank is correctly filled with water

Remarks:

Domestic hot water production has stopped but can
nonetheless be restarted using key

(For 72 hours)

Protection against corrosion is not ensured

B33

The impressed current anode is short-

circuited.

Check that the connection cable between the PCU PCB and the

anode is not short-circuited

Check that the anode is not short-circuited

Remarks:

Domestic hot water production has stopped but can
nonetheless be restarted using key

(For 72 hours)

Protection against corrosion is not ensured

B40

Measurement error on the domestic hot

water temperature sensors.

Remarks:

This message is only displayed on initial

commissioning.

This message disappears after 10
minutes or when you press the

key.

The 3 sensors do not measure the same value

Check the location of the sensors.

Err
BuS

No communication between the control

panel and the PCU board.

Check the wiring between the control panel and the PCU board.

InIt
12

No communication between the control

panel and the PCU board.

Check the wiring between the control panel and the PCU board.

If the causes of the problem are still present after several attempts at

automatic start-up, the appliance goes into lockdown mode (also

called failure).
