Type 5: Data error in control circuit alarm
To solve this type of error you need to make a total reset with the advanced setup feature.
If this does not solve the error, the circuit has to sent back for a factory reprogramming.
See 5 in table below
Type 6: Fire alarm contact (connected to external fire alarm system)
See 6 in table below
Type 7: maintenance alarm. It can be configured in 2 steps (via the advanced setup):
