Help! My Dometic Penguin II ACs with heat pumps are not working in my Motorhome. Need your input!

I recently installed two new Dometic Penguin II AC units with heat pumps in my Beaver Motorhome. The ACs work great with the old controllers and thermostats, but the old units can't operate the heat pumps. I need someone to help me figure out what's wrong or how to fix them.

The AC units are Dometic Penguin II Rooftop Air w/heat pump Model# 651916H751JO-M with Dometic Controller: Controller #: 3313189.023 and three wire T-Stat #: 3313197.000.

I believe I have the wrong controller and there is something wrong with mine or the AC may be wired wrong. I need someone smarter than me to help me figure it put.

If anyone has any ideas, I would greatly appreciate it. Thanks in advance!
