    Hey all.
    My tripac cycles when the coolant temperature (shared coolant with truck) drops below 30F. It turns on and off many times in one hour as soon as coolant reaches 30F.
    I asked Thermo King to set it to a lower temp, maybe 15F, and they claim it's not adjustable.
    Seems to me it causes alot of unnecessary wear and tear.
    Is there a place I can disable it or install a switch to control it?

    Not sure what they can do. Mine doesn’t do that. It’s an Evolution. It will stay on 30 minutes or so and shut off about the same, depending how cold it is.

    Maybe it's a different sensor location. I'd be happy to have the ability to turn the feature on and off.

    When the outside temperature is colder, say 15F, the duty cycle is much better.

    I dont know why they would set the sensor for 35F. Way too high.

    with any laptop you can use the tripac USB cable and free Thermoking Tripac Evolution Diagnostic tool to set minimum run time and startup threshold voltage, they way you can set it to start when batteries are only 12.7, and if it starts for battery voltage or arctic temp threshold it will run for minimum X time you set, 45 minutes, an hour, two hours...

    see 'run time period' and 'minimum charge duration'
