    This is the best thermostat. I tried two others and then this one. Airxcel got it right, now I am thinking about replacing the one in the living room. I really like the back light that is on all the time.

      RV Garbage, Not Reliable
      Reviewed in the United States on April 2, 2026

      Full content visible, double tap to read brief content.

      Purchased this product used for one summer. Now a year later the thermostat has gone bad. Set thermostat at 72 degrees a/c cooling. Woke up the next morning with the room at 62 degrees. Checking the temperature settings it showed the thermostat setting at 72 degrees.

      A/C would not shut off when I change the thermostat setting to 78 degrees. Had to change the A/C settings to cool off and fan off.

      My experience with any thing labeled RV is a POS will not purchase again.

      If using with Furrion rv furnace you will need to install an isolation relay in line or voltage spikes from the furnace control board will fry the resistor and your furnace will not come on. Easy fix for long time use, other than that great tstat. At least that was my experience
