Dip switches on a PB105

[AndrewChurchill]

I see that on the control panel there are some dip switches. I have read the manual several times but there are no references as to what they do. Even drawings of the control panel show a little box where the dip switches are but there is no mention of what they are.

If anyone knows what they control please let me know.

Thanks,
Andy

It's a secret that Harman is taking to the grave...

Sorry, but I couldn't find anything, other than someone makes a breadboard with the same model number. I suspect that these switches change certain aspects of the operation of the boiler ie: different reset ratio or defeat of certain safety features. Harman tech support probably knows, but they also probably won't tell you about it unless you had a specific problem.

Just flip 'em all and see what happens! ;-)

PS: let the cat go! He's innocent, I tell 'ya!
