- The large bottom knob controls the water temperature. Rotate it towards the red indicator for hotter water and towards the blue indicator for colder water.

- For safety, the valve has a preset stop at 38°C (100.4°F) to prevent accidental scalding. To exceed this temperature, you may need to press a safety override button (refer to specific valve instructions if applicable).
