APU Question > Comfort-Pro APU - starts automatically every 5 min - truck engine is off

APU Question > Comfort-Pro APU - so this Comfort-Pro APU -

PROBLEM > APU starts automatically after the truck is Stopped ---- this happens hours after the truck has stopped and the motor is turned off.

after turning on .. by itself --- I turn APU OFF -- then in 5 min, it STARTS AGAIN -

can anyone tell me what is causing this?

Thanks in Advance

======================================================

HERE IS THE FIX:

> You got the APU programmed to keep the batteries topped off - when it hits below a set voltage.

If it turns on immediately the voltage is set pretty high or the batteries are weak.

Think it’s called the battery monitor.

Comfort Pro is a top-of-the-line system made by Carrier

GYPSY >> you actually had the issue pegged - - here was the fix

You got the APU programmed to keep the batteries topped off - when it hits below
a set voltage.

** so on a 34-hour break, the batteries got LOW and the APU kicked in to top
off the batteries at 1 am }
