Error code
Description
H02.23
System water flow error active
Flow problem
No circulation:
Check that the circulation pump is working,
Check that the valves and thermostatic valves are open,
Check the wiring,
Check the pump supply: if the pump does not work, replace it.
Too much air: completely vent the indoor module and the installation for optimum running.
Incorrect wiring: check the electrical connections.
Flow meter:
Check the electrical connections and the direction of the flow meter (arrow to the right).
Replace the flow meter if necessary
H02.25
Titan Active System short circuited or on an open circuit
Check the connection cable.
Check that the anode has not short-circuited and is not broken.
H02.36
Functional device has been disconnected
No communication between the central unit PCB and the additional circuit PCB
Check the connection of the supply cable between the PCBs.
Check the connection of the BUS cable between the PCBs.
Run automatic detection.
H02.37
Uncritical device has been disconnected
No communication between the central unit PCB and the additional circuit PCB
Check the connection of the supply cable between the PCBs.
Check the connection of the BUS cable and the PCBs.
Run automatic detection.
H02.60
The zone doesn't support the selected function
H06.01
Heat Pump Unit Failure occured
Heat pump outdoor unit fault
Check the wiring between the central unit PCB and the communication bus on the outdoor
unit.
Check the connection of the communication cable between the central unit PCB and the in
terface PCB.
Check the connection of the supply cable between the central unit PCB and the interface
PCB.
Check the connection of the outdoor unit supply cable.
11.2.2 SCB-10 error codes
An error code is a temporary status, resulting from the detection of a heat
pump anomaly. The control panel attempts automatic restart of the heat
pump until it switches on.
