hayward pro logic controller is doing random stuff

[wulliwupp]

without touching my wall control unit my pool is doing random stuff.
some days ago when i went to bed i heard my pool pump still running. i went to the wall control unit and realized that the pool is set to spa party.
okey i thought it was a one time thing.
two days later my heater was on although it was manually set to off mode.
today the spa party mode is set again.
does anybody have an idea what could be going on?
if there will be a defect board i could change it by myself. i soldered the board some years ago due to the well know salt system problem. i put a new soldering point on the panel. since the it worked fine.
if there might be a bigger defect i would like to upgrade the panel to something that can be used by app. any recommendations?
