  3. Pre-set Temperature: 38°C.
  4. Safety Mechanism: The mixed water will be immediately cut off when the cold supply is not effective.
  5. Precise Temperature: It takes approximately 5 seconds to achieve the desired temperature. The actual working temperature will be within ±2°C of the temperature.
  6. Temperature Stability: The outlet temperature variation will be within ±2°C when the inlet temperature is stable and the hot and cold pressure varies by 50%. The outlet temperature variation will be within ±2°C when the inlet pressure is stable and the hot supply temperature increases from 60°C to 75°C (5°C/min).
