Dometic 3109226.005 Electronic Control Kit - Comfort Control

In this review of the Dometic 3109226.005 Electronic Control Kit the bottom line is clear: this is a purposeful replacement control center for owners of the Dometic 630035 ducted air conditioning system who need reliable comfort control. The reviewer found it straightforward to identify as a like-for-like control box replacement that restores familiar functions and makes mobile living more comfortable. It is not a modern touchscreen thermostat or universal controller, but it is a solid repair part when compatibility with Duo-Therm original Confort Control Center electronics is required.

Key Features

• Direct replacement compatibility: The control board is compatible with Duo-Therm original Confort Control Center which helps ensure the unit will interface with existing 630035 ducted systems without rewiring.
• Built for mobile environments: As a Dometic part made from quality materials, it is intended for RVs, boats, trucks and campers to sustain regular vibration and movement.
• Compact packaged size: The kit ships in a package sized about 19.304 L x 8.128 H x 25.146 W cm, making it easy to store until installation.
• Lightweight shipping mass: With a package weight of 2.649 pounds it is simple for owners or technicians to handle during replacement.
• OEM lineage: Because the control board is designed for Duo-Therm original Confort Control Center systems, it preserves original system behavior rather than introducing new features or a learning curve.

Who It's For

This control kit is aimed at RV and marine owners who use the Dometic 630035 ducted air conditioner and need a compatible replacement control board. It is a practical option for technicians and DIYers comfortable confirming part fit and performing an electrical replacement on their existing control box.

Owners seeking a newer thermostat interface, Wi-Fi control, or compatibility with CCC2 thermostats should look elsewhere, because this kit specifically replaces the original Confort Control Center electronics and will not work with CCC2 models.
