I have a controller that says Landis Staefa and has a part number of 578 655 does anyone know what this is and what I need to check the program in it?
Thats an older Talon Raptor. You would need the Raptor Block Programmer, and hope the debug file is in it.View attachment 309881 View attachment 309891 Here is a couple of pictures of it.
It depends on the version, but there is a Talon block that was used a lot. Howevere it has a bug in it. You could power it down but DO NOT DO THIS untill you change the battery to a new one. The Lon table is held with it. If the battery is dead and you power it down say good by to the table. No table no talk.This one is running a tower and circ pumps for a heat pump loop and it doesn't switch pumps when I kill the pump that is running.
