Description
Configuration Error
Parameter Error
CSU does not match CU type
Water Pressure Error active
Check the hydraulic pressure in the heating circuit.
Partial blocking of the device recognized
BL input on the central unit PCB terminal block open
Full blocking of the device recognized
BL input on the central unit PCB terminal block open
System water flow error active
Flow problem
Insufficient flow: open a radiator valve.
The circuit is clogged:
Check that the filters are not obstructed and clean them if necessary.
Clean and flush the installation,
No circulation:
Check that the valves and thermostatic valves are open,
Check that the circulating pump is working,
Check the wiring,
Check the pump supply: if the pump does not work, replace it.
Titan Active System short circuited or on an open circuit
Functional device has been disconnected
No communication between the central unit PCB and the additional circuit PCB

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.
When one of the following codes is displayed and the heat pump cannot
restart automatically, contact a maintenance technician.
Description
Buffer Tank temperature sensor is either removed or
measures a temperature below range
Buffer Tank temperature sensor is either shorted or measures
a temperature above range
Buffer Tank top temperature sensor is either removed or
measures a temperature below range
Buffer Tank top temperature sensor is either shorted or
measures a temperature above range
Buffer Tank temperature sensor was expected but not
detected
Buffer Tank Top temperature sensor was expected but not
detected
Cascade Flow temperature sensor is either removed or
measures a temperature below range
Cascade Flow temperature sensor is either shorted or
measures a temperature above range
