Why RV Humidity Control is a Game-Changer
Living in a small, sealed box means every bit of moisture you produce—from breathing, cooking, and showering—gets trapped. A standard RV thermostat only reacts to temperature, leaving humidity to run wild. This is how you end up with that clammy, uncomfortable feeling even when the A/C is blasting.
More importantly, uncontrolled humidity is the number one enemy of an RV’s structure. It fuels mold and mildew growth within walls, under flooring, and in cabinets, leading to serious health issues and costly rot. A simple "on/off" thermostat can’t solve this because it often over-cools the air without actually removing enough moisture.
A thermostat with humidity control, or a hygrometer, changes the game entirely. It actively monitors the moisture in the air and runs the air conditioner or a dedicated dehumidify cycle specifically to dry things out. This means creating a comfortable, healthy environment that protects both you and your investment. It’s one of the single most impactful upgrades you can make for full-time living.
Micro-Air EasyTouch: Ultimate Smart RV Control
Control your RV's climate remotely with the Micro-Air EasyTouch thermostat. This programmable thermostat features WiFi/Bluetooth connectivity and a large color touchscreen for easy adjustments.
The Micro-Air EasyTouch is the thermostat for nomads who want total control, whether they’re inside the rig or a thousand miles away. It replaces most Dometic, Coleman-Mach, and other common thermostats, bringing ancient RV HVAC systems into the modern age. Its full-color touchscreen is intuitive, but the real power lies in its Wi-Fi and Bluetooth connectivity.
From your phone, you can adjust the temperature, set schedules, and monitor the inside humidity from anywhere with an internet connection. Imagine turning on the A/C to dehumidify the rig an hour before you get back from a long, sweaty hike. That’s the kind of practical convenience the EasyTouch delivers. It also gets regular firmware updates, so the device actually improves over time.
While it’s one of the more expensive options, the investment pays off in functionality. It can control multiple A/C units and furnaces from a single screen, simplifying complex multi-zone systems. The key takeaway is this: if you want smart-home-level control and data about your RV’s climate, the Micro-Air is the undisputed champion.
Dometic CT Thermostat: A Sleek OEM Upgrade
Easily control your RV's climate with the Dometic CT Standard Thermostat. Its intuitive design and large, backlit LCD display provide clear temperature readings and simple operation for both ducted and non-ducted rooftop A/C units.
If you have a newer Dometic system, the Dometic CT Thermostat is a fantastic and straightforward upgrade. It features a clean, single-zone capacitive touch interface that feels much more modern than the clunky button-based models. The blue backlight is easy to see at night without being blinding.
The real benefit here is its simplicity and built-in humidity sensor. While it lacks the Wi-Fi smarts of the Micro-Air, it directly monitors and displays the interior humidity level. When in "Auto" mode, it intelligently cycles the A/C compressor and fan to maintain both your set temperature and a reasonable humidity level, preventing that damp feeling.
Think of the Dometic CT as a reliable, factory-plus solution. It’s not about remote control; it’s about providing a better, more comfortable environment when you’re inside the RV. Installation is often a simple plug-and-play swap for existing Dometic thermostats, making it a low-hassle upgrade for a significant comfort boost.
Coleman-Mach Bluetooth: Simple Wireless Access
Not everyone needs or wants to connect their RV thermostat to the internet. For those who just want the convenience of wireless control from inside or just outside the rig, the Coleman-Mach Bluetooth thermostat is a perfect fit. It does exactly what it says on the tin: it lets you control your Coleman-Mach A/C and furnace from your smartphone via Bluetooth.
Control your RV's climate with this 12V DC digital Bluetooth thermostat. Easily adjust temperature and fan speed from up to four connected smart devices, all displayed on a clear, backlit LCD.
This is incredibly useful for making small adjustments without getting out of bed or for turning on the fan while you’re sitting at the campfire right outside. The app is basic but functional, showing you the current temperature and humidity. It allows you to run the A/C to manage that humidity, though it’s less automated than more advanced models.
This thermostat represents a practical middle ground. You get modern wireless convenience without the complexity or potential security concerns of a Wi-Fi-connected device. It’s a solid, reliable choice for the RVer who values simplicity and practicality over having every possible bell and whistle.
Furrion Chill HE: Powerful Dehumidify Mode
Experience superior RV cooling with the Furrion Chill HE 13.5K BTU air conditioner. Its dual-fan system delivers faster, more efficient cooling with 50% higher capacity and 40% greater energy efficiency, all while operating 50% quieter. Built for durability with VibrationSmart and ClimateSmart technologies, it ensures reliable performance on any journey.
Furrion’s climate systems are built for performance, and their thermostat, when paired with a Chill HE (High Efficiency) air conditioner, offers a standout feature: a dedicated "Dehumidify" mode. This isn’t just running the A/C on low. It’s a specific cycle designed to pull maximum moisture from the air.
In this mode, the system prioritizes moisture removal over aggressive cooling. It runs the compressor in short, efficient bursts while keeping the fan speed low to allow more moisture to condense on the coils. This is a lifesaver in extremely humid environments like the Florida Keys or the Gulf Coast, where standard A/C cycles can leave you feeling cold but still clammy.
The Furrion thermostat itself is clean and simple, with backlit touch buttons. But the real reason you choose this system is for that powerful, dedicated dehumidifying capability. If you plan to spend significant time in high-humidity climates, a system with a dedicated dehumidify mode like Furrion’s is a non-negotiable feature.
GE Profile Thermostat: For Quiet, Dry Air
Ensure your GE oven cooks precisely with the genuine WB23T10015 sensor. This authentic replacement part guarantees accurate temperature control for your range or stove.
For many nomads, peace and quiet are just as important as temperature. The GE Profile series of RV air conditioners are known for being exceptionally quiet, and their thermostat is designed to leverage that strength while managing humidity.
Paired with a GE Profile A/C, the thermostat offers a "Dry Air" mode. Similar to Furrion’s system, this mode focuses on wringing moisture from the air, but it does so with an emphasis on quiet operation. It adjusts fan speeds and compressor cycles to remove humidity effectively without the roar of a traditional RV A/C unit kicking on and off all night.
This system is the ideal choice for light sleepers or anyone working from their rig who can’t stand constant background noise. You’re not just buying a thermostat; you’re investing in an integrated system designed for a quiet, comfortable, and dry living space. It’s a premium experience for those who prioritize a serene environment.
Truma CP Plus: Precision European Climate Tech
Protect your Truma AquaGo from freezing temperatures down to -4°F with this electric antifreeze kit. Enjoy continuous, gas-free operation and eliminate the need for winter draining with its simple plug-and-play installation.
If your RV is equipped with a Truma Combi or VarioHeat furnace, the Truma CP Plus control panel is your command center. This isn’t just a thermostat; it’s an integrated climate control system that reflects precision European engineering. It manages your furnace, and if you have a Truma A/C, it controls that, too.
The CP Plus features an "Auto Climate" function that is incredibly sophisticated. You set one desired temperature, and the system automatically decides whether to use the furnace, the air conditioner, or just the fan to maintain it. In doing so, it inherently manages humidity by running the A/C as needed to dry the air, ensuring a stable and comfortable interior climate.
The digital interface and rotary dial allow for very precise adjustments. This system is less of a universal swap and more of a dedicated controller for Truma-equipped rigs. For those with Truma hardware, the CP Plus offers a level of seamless heating and cooling integration that other brands can’t match.
Key Features for Choosing Your RV Thermostat
Picking the right thermostat comes down to your rig, your travel style, and your tech comfort level. Don’t just buy the one with the most features; buy the one that solves your specific problems.
First, compatibility is king. A thermostat is useless if it can’t talk to your air conditioner and furnace. Double-check if a potential upgrade is a direct replacement for your existing Dometic, Coleman-Mach, Furrion, or other brand. Some, like the Micro-Air, are broadly compatible, while others, like the Truma CP Plus, are brand-specific.
Next, consider how you want to interact with it. Your main choices boil down to a few key areas:
- Connectivity: Do you need Wi-Fi to monitor your rig remotely (and your pets) from anywhere? Or is Bluetooth for short-range control from your couch or campsite enough? Or do you prefer a non-connected, reliable wall unit?
- Humidity Control: Does the thermostat simply display the humidity level, or does it have an active dehumidify mode? For serious humidity challenges, a dedicated mode that cycles the A/C intelligently is far superior.
- User Interface: Are you comfortable with a touchscreen and app-based controls? Or do you prefer the tactile feedback of physical buttons that you can operate in the dark without looking?
- System Integration: Are you just controlling a single A/C and furnace? Or do you have a multi-zone system with multiple units that needs a more advanced controller to manage everything seamlessly?
Ultimately, the best thermostat is one that makes your small space healthier and more comfortable. Think about your biggest frustration—whether it’s noise, dampness, or lack of remote control—and choose the tool that best solves it.
Upgrading your thermostat is about more than just a fancy new gadget on the wall; it’s about taking proactive control over the health and comfort of your mobile living space. By managing humidity, you’re not just making yourself more comfortable—you’re protecting your home from the inside out. Choose wisely, and you’ll breathe easier on every adventure.
