APU help

Thats a setting on the TKs. I took mine to the TK and told them what I wanted and they fixed it right up for me.

 

Thats how it is on my 2013 KW.
I just hit mode button again to restart heater or A/C, its not too hard

 

You just need to push that reset button. The KW's are nightmares electric-wise and I know our Thermoking APUS had lot's of issues. They started replacing them about the time I moved on.

 

You want your apu running the whole time your truck is parked while you are at home? Seems pretty wasteful.

 

Unless he doesnt have the TK diesel-fired heat unit the APU won't run very often anyway. The only time it should start is to bring the voltage up on the batteries from heat unit fan and whatever other accessories draining them down. Set at 65 degrees mine will start maybe once every 4hrs or so and run 5-10 minutes. But mine is also setup to run as a block heater so it runs frequently on cold nights regardless.

 

My APU in my Truck works the same way as yours. Yes u have to hit the mode button for heat or AC each time after u run the truck. Its working properly as its programmed. Don't about the Dock Jockey though. If he hits anything is it your DAC that gets hit or the Jockey?
