Peerless Pinnacle PI- 140REV 2 926 control

Having a problem getting into the installer menu on the new 926 control. We had to replace the old control board and had to upgrade to the 926. My dad is the plumber that installed the original boiler and he also ordered the 926 control board from his dealer. But now after installing the new board we can not get into the installer menu to set the outdoor sensor heating curve. We follow the instructions of holding S3 and S4 till it flashes 000 and change that to 825 and then says to hold S3 to enter but as soon as we hold S3 it goes to the status menu. Any help would be great as the supplier is not open on the weekend.

    Possibly the wrong access code to the menu ,try 925 instead of 825 at least if memory serve that was the access code to installer menu on most http munchkins which where just about the same thing . If not contact peerless tech service and ore check your original installation manual .
    Peace and good luck clammy
