You will need either the burner or AC I/II switches on to have hot water. On the off chance yours is plumbed to engine coolant, you may have hot water and furnace while the engine is running with both switches off.
Some people have good luck getting hot water on AC II, but AC I is just there for keeping your plumbing unfrozen at night. AC I has 2500btu heat, AC II has 5000btu heat. Burner has 55,000btu heat. If you like long, hot showers or using more than one faucet at a time, AC II will not keep up.
