Description
The Jumper King is an all-in-one diagnostic tool that lets you bypass any low-voltage thermostat—no matter the terminal style—so you can trace shorts, isolate control issues, and stop compressor short-cycling in minutes. Designed exclusively for low-voltage circuits. Works on multiple stage units including heat pumps.
