I read that the in command system needs to be programmed through one of the aux modes. I can find any thing that tells me the heaters are controlled with the in command system.
For mine 2019 3130re, the tank heater switches light when you turn them on.
Post #14 above shows a picture of the label on the heater pad. They have a built in thermostat that turns on at 45⁰F and off at 67⁰F.
For mine, there is a red in line fuse above the hydraulic system reservoir in the corner. Make sure that fuse is pushed in all the way.
Mine decided not to work when I needed them and someone told me where that fuse was. Once I pushed the fuse all the way in the tank heater switch lights started working again.
