Set the low load
The low load of the boiler can be set by you as follows:
-
- Turn the selector wheel until you reach 0%;
- Press OK;
The boiler will switch to minimum power output (low load) of the boiler;
the screen shows 0% (heating capacity).
The CO
2
value at low load must be lower than the CO
2
value at full load. The measuring procedure must be
carried out, until a constant value is achieved. Please contact ATAG, if the values should lie outside of the
applicable tolerances.
End of measuring:
- Press the back button for 5 seconds to exit chimney sweep mode.
This completes the procedure.
The maximum duration of the commissioning function, without interruption, is 20 minutes.
