Hoping someone can enlighten me on what the command "freeze node" does on the Schindler 400A. Been having issues with the LONHFI hall call boards going bad and when to many drop out it sends the duplex into fire recall for whatever reason. After pressing the freeze node command I was able to get them running in independent service but now I'm concerned as to what is going to happen when I finally get new hall call boards haha. How do I un freeze ilthe nodes. I have little to no information on these things and always fun to work on. Thanks for any insight!!
