Was the Dometic Air Conditioners Control Kit/Relay Box Heat/Cool/Heat Strip With Ct Wall Thermostat the Right Choice?
After years spent wrestling with finicky climate control systems in various environments, from dusty workshops to meticulously controlled laboratory settings, I’ve developed a keen eye for reliable equipment. My current obsession? Ensuring a consistent, comfortable temperature in my mobile workshop, a vintage Airstream trailer that doubles as a remote testing lab. The original air conditioner’s control system had finally succumbed to age, leaving me with a stark choice: a full system replacement or a targeted upgrade of the control module. Enter the Dometic Air Conditioners Control Kit/Relay Box Heat/Cool/Heat Strip With Ct Wall Thermostat. This specific Dometic offering promised to bring my aging rooftop unit back to life with modern control and functionality.
The trigger for this purchase was a definitive failure: the old thermostat had become unresponsive, cycling the unit on and off erratically, rendering the Airstream unbearable during both sweltering summer afternoons and surprisingly chilly desert nights. My prior experience with Dometic products has generally been positive, so when I saw this kit, which specifically mentioned heat and cool operation along with a wall thermostat, it immediately caught my attention. My initial impression upon unpacking was one of solid, functional engineering. The relay box felt robust, and the CT wall thermostat had a clean, understated design in its polar white finish. I had briefly considered generic universal control kits, but the thought of compatibility headaches with my specific Dometic unit steered me back towards an OEM solution. My first reaction was a sense of pragmatic relief; this seemed like the direct, no-nonsense fix I needed.
Real-World Testing: Putting the Dometic Air Conditioners Control Kit/Relay Box Heat/Cool/Heat Strip With Ct Wall Thermostat to the Test
First Use Experience
My testing ground for this control kit was my Airstream trailer, which serves as both a mobile workshop and a makeshift lab. I needed to install it within the existing air conditioning ducting and connect it to the power source and the rooftop unit itself. The installation process was straightforward for someone with my background in equipment maintenance. The wiring diagrams provided were clear, and the connections on the relay box were logically laid out.
Performance in varying conditions was key for me, as my Airstream travels across diverse climates. I tested the unit during a week of fluctuating temperatures, from cool mornings where the heat strip was essential, to afternoons where the cooling function had to work overtime. The heat/cool operation was seamless, with the unit switching modes effectively without any noticeable lag or erratic behavior. The CT wall thermostat proved to be surprisingly intuitive; its user interface was simple and easy to understand, requiring no extensive manual reading for basic operation.
The primary surprise was the thermostat’s responsiveness. Unlike the sluggish old unit, this Dometic thermostat reacted quickly to temperature changes and setting adjustments. There were no immediate quirks or issues; the installation and initial operation were as smooth as I could have hoped for, which is always a welcome change when dealing with replacement parts.
Extended Use & Reliability
After several months of continuous use, including extended periods where the Airstream was parked in direct sun or subjected to chilly nights, this Dometic control kit has proven its worth. It has reliably managed the temperature, switching between heating and cooling modes as needed to maintain a stable internal environment for my sensitive equipment and my own comfort. The polar white finish on the thermostat has remained clean and free of yellowing, resisting the UV exposure common in my mobile setup.
Durability hasn’t been an issue thus far. The relay box is tucked away neatly, protected from dust and vibrations, and shows no signs of strain. The wall thermostat, though plastic, feels substantial and has withstood daily interaction without any scratches or loose buttons. Maintenance has been minimal; a quick wipe-down of the thermostat face is all that’s typically required. I haven’t encountered any performance drops, and the heat strip functionality has been particularly robust during colder spells.
Compared to the original equipment, which I suspect was of a similar Dometic pedigree, this kit feels like a significant step up in reliability and user experience. It certainly outperforms the generic, often cheaply made universal kits I’ve dabbled with in the past, which tend to have less precise temperature control and shorter lifespans.

It includes a relay box and a CT wall thermostat, both finished in a clean polar white. The kit is composed of quality parts and materials, which is a crucial aspect for long-term reliability in demanding environments like a mobile workshop.
The relay box acts as the central nervous system, managing power distribution and signals to the various components of the air conditioning unit.

While specific dimensions and electrical ratings aren’t detailed in the provided description, the emphasis on quality parts suggests a well-engineered component designed for the rigors of RV and mobile application use. The integration of a heat strip capability means it’s not just for cooling; it can provide supplemental heat when needed.
Performance & Functionality
The primary job of the Dometic Air Conditioners Control Kit/Relay Box Heat/Cool/Heat Strip With Ct Wall Thermostat is to accurately and reliably control the heating and cooling functions of an air conditioning unit. In my experience, it performs this task exceptionally well. The heat/cool operation is seamless, with the system switching between modes without hesitation.
The thermostat’s accuracy in maintaining set temperatures is a significant strength. It maintains a consistent environment, which is vital for sensitive equipment in my lab setup. The heat strip feature also works as advertised, providing a welcome boost of warmth on cooler mornings. The only minor point for improvement might be the fan speed control, which is standard but could perhaps offer more granular adjustments on some higher-end models. However, for its intended purpose and price point, it meets and often exceeds expectations.
Design & Ergonomics
The design of the CT wall thermostat is a definite plus. Its polar white finish is understated and blends well with most interior décors, avoiding the overly “appliance-like” look of some older controls. The physical buttons are responsive and have a satisfying click, providing clear tactile feedback.
Ergonomically, it’s a winner. The layout is intuitive; there are no hidden menus or complex sequences to remember for basic operation. This simplicity is a major advantage, especially when you need to make quick adjustments or when others might need to operate the system. The overall build quality feels solid, with no creaks or flex, suggesting that Dometic has indeed used quality parts and materials as stated.
Durability & Maintenance
In terms of durability, this Dometic control kit appears built to last. The relay box is designed to be an out-of-sight, out-of-mind component, and its sturdy construction suggests it will endure the vibrations and temperature fluctuations inherent in a mobile environment. The wall thermostat, being the most handled part, feels robust. I haven’t experienced any failure points, such as cracked plastic, unresponsive buttons, or electrical issues, during my extended testing period.
Maintenance is refreshingly simple. The thermostat face can be wiped clean with a damp cloth, and the relay box requires no user maintenance. For anyone accustomed to the frequent troubleshooting of older or cheaper systems, this ease of care is a significant benefit. The heat strip component is also designed for longevity within its operational parameters.
Accessories and Customization Options
The Dometic Air Conditioners Control Kit/Relay Box Heat/Cool/Heat Strip With Ct Wall Thermostat comes as a complete kit, meaning the primary relay box and the CT wall thermostat are the core components.
