To reset the installers code to 9999
The User Code 1 will also be reset to 1111
Unplug the ac transformer and disconnect the main units back up battery then flip it over and find the pins labeled "DEF" on the circuit board. Lower right side of circuit board.
You'll need to short the two pins closest to the bottom of the powermax+ unit labeled DEF,a metal paper clip works just fine.
Have someone plug in the ac transformer while holding the short.Hold this for 10 seconds then unplug the transformer before removing the short.
Remove the short and turn the unit over, plug it back in and try 9999 as the Installer's Code.
(If the reset did not work the first time, try again making sure the short between the def points remains closed during the 10 second power up.)
