The code 110:Lockout SLT is displayed when overheating occurs due to a
breach in the insulation:
Remove the heat exchanger.
Replace the insulation behind the burner bracket.
Replace the safety thermofuse behind the heat exchanger.
Error 162:Air pressure switch
The error 162:Air pressure switch signifies that the flue gas differential
pressure switch has been triggered several times over the last 24 hours.
Check that the air inlet and combustion products discharge pipes are not
blocked. Unblock these if necessary.
After this procedure, proceed as follows to restart the boiler:
1. Unclip the HMI by hand then remove it from its support: pull firmly on
the slots at the bottom of the HMI.
2. Press the red button RESET on the boiler for 1 second using a
pointed object.
3. Clip the HMI back onto its support.
If the symbol is displayed at the same time as the error code, the error
code is automatically cleared when the cause that prompted it stops.
A flow or return temperature in excess of the critical value prompts an
error code. The error code is automatically cleared when the temperature
drops below the critical value.
