Alpha Pro Tec - Programming the Boiler PCB
The boiler is supplied with the PCB configuration set according to the boiler model, however it is possible to adjust certain
parameters according to the boiler and system configuration.
Note:
These parameters should only be adjusted by an approved Alpha engineer or Agent.
To access the programming menu, press and hold buttons 'B'
and
'C'
simultaneously. The screen will display the letter P and a corresponding
parameter number and then display the corresponding set value for that
parameter. Scroll through the parameters by using the CH + and – buttons
('1' as shown in Fig. 9.1). To change a parameter value press the DHW +
and – buttons ('2' as shown in Fig. 9.11) to the desired value.
The parameter value is stored by either moving to the next parameter or by
pressing button 'B'.
Exit the parameter menu saving your new settings by pressing the buttons
'B'
and
'C' simultaneously. The boiler will then run a self-diagnostics cycle
displaying PARA and Auto on the screen.
Note:
After approximately 2 minutes the boiler will automatically exit this
menu without saving any changes and running a self-diagnostics cycle displaying PARA and Auto on the screen.
