Values of A0 (in P0), A1 (in P1) or A2 (in P2) are made to increase / decrease fan
speed according info in the manual where a recommended value in indicated. To
compare current fan speed with unit in operation with value in manual enter
parameter and wait 5 seconds until real value be displayed before adjustment.
Always check parameters according gas and model type and check results according to
the manual.

Table 16 – Adjustments Parameters for control unit configuration
To change the gas type, enter first into the service mode and then scroll to the parameter
“P7”. This parameter allows the control of the modulation range according to the gas type.
In order to ensure a proper operation of the appliance, this parameter in combination with
altitude and appliance capacity must be checked when the control unit is replaced,
otherwise output is compromised or abnormal combustion problems may occur affecting
comfort and appliance performance.
In the LPP range (W/WD/T2400), the gas type definition is made using the dip switch located in
the PCB.
