No it's programmed to run only as needed to keep the batteries charged. It runs continuously in AC mode because the compressor needs to be running for AC.
Why would you want it to run continuously?
I was thinking about getting a TV. But if it kicks in automatically then I'd be alright?
Yes you can have a TV, microwave, etc. going and it will kick on when it's needed.
Thank you very much !
Mine runs on start stop even on A/C mode.

Is it possible to run the APU continuously in heat mode like in AC mode? Thank you in advance.
APU:
Auxiliary Power Unit
On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.
Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.
