Video Transcript for Review of Dometic RV Furnace - DMC84RR

Hi, everyone. Steven here with etrailer. Today we're taking a look at our Dometic Digital Thermostat. It's gonna be for furnace control only, or your heat. Now this digital thermostat, once it's powered up, you'll have a digital out-read here and then obviously you can change the knob here to go from cool to the heat setting that you want. So again, it controls only the heat.

You got a little indicator light down here. And on the back here you got your connections for the thermostat wires. Now, I did go ahead and measure this before our time together here, but I did wanna show you on center, the mine hole center-to-center, I got two and three eighth inches, a thickness overall, I measured down here at the base, at the widest part, sticking out from the wall, it's gonna be 13/16th thick. And on the back when I measure a width, I get three and 3/8th inches wide. And when I measure a height on the backside, I get three and 7/16th inches tall.

Now it does come with a set of batteries and of course your mounting hardware with these plastic wall fasteners to go into the wall if need be. So not much more to talk about, folks. That's gonna wrap up our quick look together at this Dometic Digital Thermostat. Again, heat or furnace control only, in white. I'm Steven with etrailer.

Thanks for watching and reach out if you have any other questions.

The instructions did not tell how to change from centigrade to Fahrenheit, had to go to internet, otherwise it works fine and looks good .



by:

Two wire thermostat, digital.. it should have an off switch and more than a single page manual.

Works good. I like the digital display. I do wish that it had a off switch.

Love my new chill cube. Install was a breeze. Everything I needed was provided. The furnace thermostat installed very easy as well. Everything functions flawlessly

  • Does etrailer Carry Furrion Chill Cube w/ Heat Pump to Replace Dometic Duo-Therm
    Hey Andrew! Yes, Furrion does have a Chill Cube model with a heat pump. This was actually just released for aftermarket sale. You will need a complete system to make the switch, new R32 units aren't backwards compatible with old R410A systems. You can choose from the following based on color and ducted/ductless: -Furrion Variable Speed Chill Cube RV AC w/ Heat Pump - Ductless - 18K Btu - White - R32 # FR87TQ -Furrion Variable Speed Chill Cube RV AC w/ Heat Pump - Ductless - 18K Btu -...

  • How Does Ducted System Work With Furrion Chill Cube
    Hi JD; the Furrion Chill Cube # FR49TD air distribution box has a vent on it you can open and close. See the picture attached below. When it is closed it forces more of the air through the ducted system. Assuming you have a ducted system you will need one of the following: -Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted - 18,000 Btu - Black # FR39TD -Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted - 18,000 Btu - White # FR99TD -Furrion Chill...

  • Can Furrion Chill Cube Operate With RV Furnace
    Hello Sam; that is a great question! I reached out to Furrion and you will be able to use the Furrion Chill Cube # FR69TD (white) or # FR49TD (black) with your furnace. However, the remote is not capable of operating the furnace at this time. Also, we have found that the included wall thermostat isn't always compatible depending on the furnace you have. My recommendation is to get the # FR39TD (black) or # FR99TD (white) and then add a separate thermostat like the Dometic Digital Thermostat...

  • How to Use Furnace With Furrion Chill Cube on 2017 Keystone Cougar 327RES
    Hey Dusty! There is a lot of information out there right now about Chill Cube. Some of it is definitely confusing, especially when we have people trying to use parts that aren't designed for the new R32 systems. On top of that, the Chill Cube uses a remote which acts as its thermostat and isn't compatible with a furnace. There are two ways to make everything work together, I will give you both. The first is to get the Furrion Chill Cube RV Air Conditioner w Air Distribution Box - Ducted...

  • Can Furrion Chill Cube Thermostat Work with Furnace
    Hey Christopher, at this time the Furrion Chill Cube doesn't have a thermostat that will work with a furnace although we have heard they are working on that. So in meantime the best option is a furnace only thermostat like the part # DMC84RR which you'd wire up to your furnace independently of the Chill Cube. Is that the extent of your question or does the wiring of the thermostat still giving you troubles.

  • How to Change the Dometic Digital Thermostat Furnace Control Only to Fahrenheit
    There sure is Tim, this is America! You'll need to pull the faceplate of the Dometic Digital Thermostat item # DMC84RR off of the wall. If you look on the back of it you'll see a bunch of circuits but on the left side there's a button you can press (it's circled in the pic below). Go ahead and press it down until the display shows P01. Then release the button and turn the knob clockwise until the display shows P05. You'll press that button again and the display will show C. You'll want...

  • Will the Dometic Digital Thermostat DMC84RR Work w/a Atwood Furnace 7916-11?
    Yes, it will Stephen. The Dometic Digital Thermostat item # DMC84RR is a furnace only thermostat that is designed to work with 2-wire setups like your Atwood furnace 7916-11. The Dometic Digital Thermostat item # DMC84RR measures 3-3/8" wide x 3-7/16" tall x 13/16" thick. It is extremely easy to setup and operate. What kind of trailer or motorhome do you have?

  • Will Furnace Work With Fogatti InstaCool RV AC
    Hey Tom! The Coleman thermostat will not work with the Fogatti InstaCool RV AC # FG22FR. This is a new R32 system so an old R410A thermostat is not compatible. However, you will be able to connect your furnace to the Fogatti control panel so it can run your furnace as well. Keep in mind, the Fogatti systems are only compatible with ductless setups. If you have a ducted setup let me know in the comments below and I can help you find an alternative. What kind of trailer do you have?

  • Can Furrion Chill Cube of Brinkley Model i265 Get Moved to Bedroom and Cube Install in Living Room
    Hey Scott, this is a great question but if you move your Furrion Chill Cube to your bedroom and use it as a ducted setup you can't use a wall thermostat with it. You have to use the ceiling controls or the remote. To do this you would need the new air distribution box part # LC44DX. Then you'd leave the living room air box in place and go with the upper unit Furrion Chill Cube Variable Speed part # FR37TQ and you'd be set. So I have to mention too that the Chill Cubes just don't like...

  • Do You Have a Dometic Furnace Control Only Thermostat in Black?
    Hi Eduardo, Unfortunately, we don't have a black thermostat that is for furnace control, only like the white Dometic Digital Thermostat for Furnace Only part # DMC84RR. What you could do is use the Dometic Replacement Single Zone Thermostat for Dometic RV ACs in Black part # DMC79FR which allows for a furnace to be wired into it. If you have an air conditioner as well, you'd be able to wire both the AC and furnace to this thermostat to control both from one place. Do you prefer to have...

  • 18k BTU RV AC Unit Recommendation for Replacing 13.5k Coleman Mach
    Hey Roy, the best option for you would be the Furrion Variable Speed Chill Cube part # FR67TQ. This is an 18k variable speed compressor with a heat pump like you are wanting that is currently available right now. So the only caveat is that while the thermostat that comes with this is supposed to be compatible with furnaces we have found that it's not reliably so you would want to retain the thermostat you have now just for the furnace or use a furnace only thermostat like the part # DMC84RR....

  • Replacement for Dometic Air Conditioner in 2017 Forest River Forester
    Hey Kirk! The Furrion Chill Cube RV AC System # FR87TQ is a great replacement for the Dometic unit on your 2017 Forest River Forester, but it does change how the heating and cooling systems are controlled. The Chill Cube does not use a wall thermostat. Instead, it's operated with the included wireless remote, so your existing thermostat wiring won't be used by the new air conditioner. Because of that, you also won't be able to use a Furrion thermostat to control both the Chill Cube and...

  • Looking For Smart Thermostat To Use With Furrion Chill Cube AC unit
    Hey Danny, thanks for reaching out. Furrion is making a furnace compatible thermostat that will work with the Chill Cube, and that is part # LC74DX. Only problem is these are not available quite yet. If you need something sooner, I have heard that universal Bluetooth thermostats can work with the Chill Cube. A few customers have reported back to us that the universal thermostats work fine for controlling the Chill Cube. The official word from Furrion is to only use their thermostat, but...

  • How Much Movement is Normal for Dometic Thermostat Off/On Switch
    Hey Patricia, I am assuming you have the Dometic thermostat part # DMC84RR that you referenced. You should hear a click when the thermostat is turned off and on so it is a little concerning you aren't hearing anything. If you check out the attached review video you can hear what it will sound like around the 30 second mark.

  • How Does Coleman Mach 15 Compare to Furrion Chill Cube
    THey Brian, the Coleman Mach Signature Mach 15 part # CM32RR is a really solid AC unit. As far as how it compares to the Furrion Chill Cube # FR69TD it only has the advantage of working more consistently with furnace controls. Aside from that the Chill Cube wins in terms of cold air blowing, quietness, and amperage draw. If you'd be open to it the best setup would be a Chill Cube and then a furnace only thermostat like the part # DMC84RR. Does running a second thermostat work for you at...

  • Can The Dometic Digital Thermostat DMC84RR Be Hardwired So Batteries Are Not Needed?
    Hey John, thanks for reaching out. The Dometic Digital Thermostat # DMC84RR uses two AAA batteries to power the display and logic. You can’t really bypass the batteries completely because the thermostat needs them to function as a digital unit. Even if you hardwired constant 12V into it, it’s not designed to run that way, there’s no terminal for it. It’s built to use batteries for the electronics and the RV wiring for the furnace control separately. If your goal is “no batteries ever,”...

  • Replacement AC System for a Obsolete Carrier AC Unit
    Thanks for all the information Raymond! To replace one of your Carrier AC units, I recommend the Furrion Chill HE RV Air Conditioner System item # FR95TD. There's no way to just replace your AC unit with a direct factory replacement, you'll need to replace all your AC system components. This is due to the EPA changing the regulations on the refrigerant in the AC units at the beginning of 2025. They've been upgraded to R32 and your Carrier V has the now obsolete 410a refrigerant. None...

  • Replacement Chill Cube w/ Heat Pump AC System for a Dometic Duo-Therm
    Welcome back Gary and thanks for all the information! To replace your Dometic Duo-Therm 59516.603, I recommend the Furrion Variable Speed Chill Cube RV AC w/ Heat Pump & Air Distribution Box item # FR59TQ in white or item # FR27TQ in black. There's no way to just replace your AC unit, you'll need to replace all your AC system components. This is due to the EPA changing the regulations on the refrigerant in the AC units at the beginning of 2025. They've been upgraded to R32 and your Dometic...

  • Does Turning Dometic Thermostat DMC84RR All The Way Down Turn Furnace Power Off?
    Hello Joe, thanks for reaching out. To answer your question, no, turning the Dometic # DMC84RR thermostat all the way down does not shut the furnace completely off like flipping a power switch. The digital thermostat will command the furnace to stop firing and hold a low set point, but the furnace controller still has standby power going to it so the thermostat and display stay alive. This is how most digital RV furnace thermostats work, including the # DMC84RR.

  • What Thermostat Works With Dometic RV Furnace
    Hey Derrick! The Dometic RV Furnace # DMC94RR will pretty much work with any RV thermostat that is capable of running a furnace. The only one that might give you trouble is the Furrion Chill Cube wall thermostat since it seems to have issues with a lot of the furnaces out there. Do you already have a thermostat running your AC or an existing furnace? If you need one you can use the Dometic Digital Thermostat - Furnace Control Only - White # DMC84RR. You could also run it using a smart...

  • 20k BTU RV Replacement Furnace Recommendation for Lance Camper
    Hey Greg, yes our Dometic RV Furnace part # DMC86RR is our lowest BTU rated RV furnace. Thankfully nearly all RV furnaces are made to the same size which makes swapping them easier. For a thermostat we have the Dometic Digital part # DMC84RR which is a furnace only style thermostat that would work great.

  • What is the Amp Draw on the Dometic RV Furnace DMC86RR?
    Hey Robert, welcome back! The 20,000 Btu RV furnaces like the Dometic item # DMC86RR you were looking at draw 4.8 amps. It runs off of propane, measures 20" deep x 7" tall x 12" wide, can be installed vertically or horizontally, and works great on trailer's up to 20' long. Unless you have a compatible AC system, you'll need the Dometic Digital Thermostat item # DMC84RR to control item # DMC86RR. What kind of trailer or camper do you have and how cold are you expecting it to get where...
