2019 Freightliner Cascadia optimized idle weirdness

On mine if the temp control is on the coldest To the left Or hottest To the right It acts screwy

 

on a 2019 cascadia how do you keep the power on for a fridge when your on home time? i know it has optimum idle does it shut off and back on when the voltage gets low?

 

how do i power a 2019 cascadia while on home time? does the optimum idle shut off and back on when the volts get low im wondering if my food will go bad in the fridge?

 

You can turn it on and turn Interior Comfort Mode off. Then set sleeper fan to Off. It should only start engine when batteries hit 12.1 volts or to keep engine oil warm. If you turn on sleeper fan it will heat or cool the sleeper to the temperature the sleeper thermostat is set for.
