Expert Reply:
According to the owner's manual if your Replacement Premium Wall Thermostat for Furrion Chill HE RV Air Conditioner # FR33PR is flashing LO then that means you have an insufficient low-level 12V power supply.
I recommend checking your wiring and connections to the thermostat and ensure that you are in fact getting an adequate 12V with a multimeter # PT89ZR.
If you verify that you are getting 12Vand all of your wiring is good, come back and we can continue to troubleshoot deeper.
