Fenglesha RV Wall Thermostat — Single-Zone 3316250.712, Blue Backlit LCD & 3-Wire 12V Touch Control

The Fenglesha 3316250.712 is a single‑zone RV wall thermostat that replaces Dometic controls to manage cooling, heating and furnace operation with a blue backlit LCD and capacitive touch interface.

This compact thermostat is designed for recreational vehicle climate systems and fits many Dometic models. It runs on 12 V DC, uses touch‑sensitive controls instead of mechanical buttons, and supports fan modes for low, high or automatic operation. The unit displays settings on a clear blue backlit screen and handles temperatures from 40°F to 90°F.

How does this thermostat control my RV air conditioning and furnace?

The Fenglesha 3316250.712 sends standard on/off signals suitable for many Dometic units so it can switch between cooling and heating circuits and activate the furnace. It provides simple setpoint control rather than complex zoning, making it easy to operate while on the road.

• Single‑zone control for one temperature circuit
• Works with a range of Dometic model numbers for A/C compatibility
• Switches between cool, heat and furnace modes
• Blue backlight makes the display readable at night

What makes the capacitive touch panel different from mechanical buttons?

Capacitive touch sensing gives the thermostat a flat, modern surface that responds to light taps rather than clicks. This reduces wear from repeated use and creates a smooth finish that’s easier to wipe clean in an RV environment.

• Touch control for setpoint and mode selection
• Sleek, flush front reduces dirt and moisture traps
• Fewer moving parts increase long‑term reliability
• Immediate response and minimal force required

Which RV systems and Dometic models are compatible?

The thermostat is built to match common Dometic signaling and works with a wide selection of models used in RVs and campers. Confirm wiring and model compatibility before purchase, as some older or specialized systems require different control types.

• Compatible with many Dometic part numbers (check model list before install)
• Designed for 3‑wire installations on 12 V DC systems
• Supports typical A/C, heat and furnace control wiring schemes
• Temperature range suitable for most RV climates (40–90°F)

How easy is installation and what are the technical basics?

Installation is straightforward for users familiar with RV thermostat wiring; the 3‑wire connection and 12 V DC power are standard for many rigs. If you’re not comfortable working with low‑voltage wiring, professional installation is recommended to ensure safe and correct operation.

• 12 V DC power requirement for the display and controls
• 3‑wire connection—confirm wire colors and functions before wiring
• Plug‑and‑play replacement for supported Dometic models when wiring matches
• Manufacturer offers a 2‑year warranty for defects
