Johnson Controls Y199AAA-2 Digital Setup Tool

Got this Johnson Controls Y199AAA-2 digital setup tool. It's a handheld programmer used for setting up and troubleshooting various HVAC controllers and modules. Comes with the original black carrying case and the test leads shown in the photo. Everything looks to be in decent shape, just a bit of normal wear from being in a tool bag. If you do HVAC work and need one of these older interface tools, this is a solid find.
