RV Wall Thermostat Kit Fits Dometic Single Zone LCD Touch - Easy

In this review of the RV Wall Thermostat Kit (3316230.000) the bottom line is simple: this kit is aimed at RV and trailer owners who need a direct replacement for Dometic single zone controls and want a clear, modern interface. The reviewer found installation straightforward for users familiar with RV AC wiring, and the large blue-backlit LCD plus capacitive touch controls make daily temperature adjustments easier than older mechanical thermostats. It replaces several factory part numbers, so it is primarily useful when matching a specific Dometic model or replacing a failed wall thermostat and relay box.

Key Features

• Specific application: Compatible with multiple Dometic air conditioner series and models, which simplifies finding the correct replacement for many single zone RV AC units.
• Complete control kit: Ships with the white thermostat, relay control box and a hardware pack so users have the parts needed for a direct swap in most installations.
• LCD display: The large custom LCD with blue backlight offers easy readability of temperature, mode and set point in bright or low-light conditions.
• Capacitive touch panel: Three touch input areas provide access to cool and furnace modes plus low/high/auto fan speeds without mechanical buttons that wear out.
• Replacement coverage: Replaces several part numbers including 3316230.000 and related variants, reducing uncertainty about compatibility when ordering.
• Support and warranty: The kit includes a 30-day refund policy and a 12-month warranty for quality-related issues for added peace of mind.

Who It's For

This kit is best for RV and trailer owners running Dometic single zone air conditioners from the compatible series (540, 4579, 4595, 640) who need an OEM-style replacement for a failed wall thermostat or relay box. Technically inclined owners or mobile technicians who can verify wiring and mount a relay box will find the swap straightforward and reliable.

If you have a multi-zone system, a non-Dometic brand AC, or want a thermostat with advanced smart-home connectivity, this is not the right choice; it is designed as a like-for-like replacement focused on basic cool/furnace control rather than Wi-Fi or remote features.
