Code Faults

Cause
of the
fault

Description

Checking / solution

D17

DHW 2 S.FAIL

SCU

Sensor fault tank 2

Bad connection

Check whether the sensor is connected:

See chapter: "Deletion of sensors from

the memory in the PCB", page 79

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

D27

PCU COM. FAIL

SCU

Communication failure between the SCU and PCU PCBs

Check the wiring between the SCU and PCU PCBs

Check that the PCU PCB is powered up (green LED on or flashing)

Change the PCU PCB

D32

5 RESET:ON/OFF

SCU

5 resets done in less than an hour

Switch the boiler off and switch back on

D37

TA-S SHORT-CIR

SCU

The Titan Active System® is short-circuited

Check that the connection cable between the SCU 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

The tank is no longer protected.

If a tank without Titan Active System® is connected to the boiler,check that the TAS

simulation connector (delivered with package AD212) is fitted to the sensor card.

D38

TA-S DISCONNEC

SCU

The Titan Active System® is on an open circuit

Check that the connection cable between the SCU PCB and the anode is not severed

Check that the anode is not broken

Remarks:

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

The tank is no longer protected.

If a tank without Titan Active System® is connected to the boiler,check that the TAS

simulation connector (delivered with package AD212) is fitted to the sensor card.

7.4.1.

Deletion of sensors from the memory in the
PCB

The configuration of the sensors is memorised by the SCU PCB. If a

sensor fault appears whilst the corresponding sensor is not

connected or has been voluntarily removed, please delete the sensor

from the SCU PCB memory.

Press key

repeatedly until

Do you want to delete this

sensor?

is displayed

Select

YES

by turning the rotary button and press to confirm.

The outside temperature sensor cannot be deleted.
