Question:

Does the furrion thermostat part number LC74DX control the ducted chill cube and the heater in my trailer. It currently has a furrion ducted ac with furrion wall thermostat than controls heat too. Thanks

Hello Justin, thanks for reaching out. Yes, the # LC74DX thermostat will be able to control the AC unit as well as your heater. We have been getting this question a lot lately, so this has been confirmed with Furrion. It isn't available quite yet though. If all goes well, you should be able to get one in like 4-6 weeks.

While the thermostat will control a furnace, the implementation fails on several levels. First, the thermostat does not keep separate heat/cool settings, so when changing between heat and cool, the user must also redo the desired temperature. i.e. if you had cool set to 76 degrees and switch to heat, it's going to heat to 76 degrees unless you change it manually. Second, the thermostat does not support a furnace when in Auto mode. So you can't set a temperature range you want to maintain. i.e. it won't automatically switch between heat and cool to keep the temperature between 60 and 70. You must manually switch between heat and cool at the thermostat. Third, heat mode cannot be set or controlled using the remote. Even though the remote itself will cycle through a heat mode, the ADB and thermostat ignore it. The follow me feature does not work in heat mode.
