The most comfortable temperature for sleeping realized by temperature control specialist KD Navien

This technology allows sleeping at the optimal temperature for each individual taste through the intelligent smart separation heating adjusting the left/right temperature precisely by 1℃, matching the set temperature, of the mat and boiler by controlling the returning temperature, and ensuring, consistent temperature over the entire mat without temperature fluctuation. All of these features can only be realized by KD Navien.

Safety first design system

In designing a product, KD Navien researchers put the highest priority on “safety.”

High-temperature mode notice function

Check the temperature for safety again.

Get notified about the safety temperature when the temperature increases to 38℃ or over. When the Caution lamp is on, the temperature is too high.

Child lock mode

You can feel safe, even when your child carelessly touches the product.

Curious children tend to touch everything without us ever knowing When the child lock mode is on, the button cannot be controlled. So you can relax a bit more about your child’s safety!

Multi-layered safety system

System with the highest priority on safety

You can feel safe with the water inlet and cover, which features multiple barriers, and the connector guard without worrying about direct contact with the hose.

  • Horizon maintenance sensor to turn off power automatically in case of

    imbalance by monitoring the boiler
  • Overheat prevention system to prevent any fire risk by detecting overheat in the

    hot water tank and heater
  • The timer turns the system off automatically after 15 hours of

    non-stop operation for safety.
  • The water level sensor alerts when

    the water level is low.
  • It operates automatically when the temperature falls below 5℃ to keep the

    system from freezing.
