Quick Thermostat for Nautic Boilers - FVSLTB152700A00

Key Performance Features

• Dual-Function Control: Acts as both a standard operating thermostat (cycling power on/off) and a high-limit safety cut-off.

• Manual Safety Reset: Features a dedicated "Reset" button (usually red or black) that trips if the water temperature exceeds a safe threshold (approx. 80∘$\text{C}$ or 176∘F). This prevents the tank from over-pressurizing if the primary control fails.

• Adjustable Temperature Range: Allows the user to fine-tune the hot water temperature, typically between 40∘$\text{C}$ and 80∘C.

• Plug-and-Play Interface: Features standard spade-terminal connections for easy wiring and a probe design that fits perfectly into Quick FVSLRS series heating elements.

• Bipolar Safety: Disconnects both the Phase and Neutral lines when the safety limit is reached, providing a higher level of electrical safety in marine environments.

Troubleshooting: "My water isn't getting hot."

Before replacing the thermostat, check the following:

1. The Trip Switch: Remove the plastic cover on your water heater and look for the small reset button on the thermostat. If it has popped up, press it back in. If it trips again immediately, the thermostat or the heating element is likely faulty.

2. Element Continuity: If the thermostat is sending power but the water stays cold, your heating element (like the FVSLRSB12110A00) may be burnt out.

3. Scaling: Heavy mineral buildup on the internal probe can "insulate" the thermostat, causing it to read temperatures incorrectly and shut off prematurely.
