Pro power and AC on at start

[Mal106]

This seems off track. I am asking if there is a way to start the truck and NOT have ANY pro power or AC come on. It seems turning the fan off does the trick as far as the AC is concerned. Haven't figured out the pro power yet. Thanks for all the inputs.

If you open the window for Climate, you'll see OFF.

As to Pro Power, there is no Pro Power on except the in-cab outlets, and they're using no power. If the limit warning bothers you, LOWER it.

The Pro Power On Board involves a DC to AC conversion, and when the process is on, some energy is used even when there is no load on the AC outlets.

That is, there will necessarily be some energy/power used by the circuitry used for the conversion process to put the 120VAC at the outlet, even without a load.

Why?

There is always some so-called idle or quiescent current in the components used to convert from the HV battery DC to the outlet's 120VAC when they (the converter circuitry) are on, load or not.

Yes, even though this is a relatively small amount of energy/power, over time it can add up and is taking energy from the battery, which is why the OP sees the warning about it.

This is different from say your house outlets (in a way) - with no load the house system is not using any energy/power - but of course some energy/power is being expended by the utility to provide your house with energy, for example in the step-down transformers humming up on the pole, the humming means current is flowing through them - transformers are coils of wire and wire has resistance and resistance time current squared means some power lost to heat as well as magnetic fields - the utility also loses some energy/power through the distribution system from generator to transformer.

I use "energy/power" because power is the rate at which energy is used/transferred, and in common usage they are used interchangeably..

Well described chl, thanks. The small amount used when I don't need or want it is, no doubt, negligible. It's the geek in me.

and why we are on that question..... has anyone figured out the timeout for ACC NOT full start... when U use ACC the dc to dc still keeps the 12v battery going BUT it does not spin up the power steering pump and AC compressor tho the fan still comes on in the cab I use pro power quite a bit on a 23 platinum.... but it times out in 30 mins... I know U can override it in drive condition but want to find where in forscan to disable that 30 min timer... for ACC position as well.
