●Remote Control
You can control your water heater from your smartphone.

When you want to take a bath as soon as you get home, such as on the way home from leisure activities or after dropping off your child at an after-school activity, you can remotely control the water temperature while you're away from home.

If you forget to turn off the bath's heat setting or floor heating, you can control it while you're out, or even from bed at night.

You can connect to the bath and control it from anywhere, without having to be near the remote control, reducing the burden of housework.

●Monitoring Function
You can check the bathroom status, giving you peace of mind by checking on your family's bathing status even when you're out.

To prevent family members from taking long baths, the app displays the bathtub usage status and sounds an alarm on your smartphone when the set bathing time has elapsed.

You can also call the bathroom remote control from the app.

You can also check the hot water usage status of family members who live far away using the app.
The app will notify you the next morning of hot water usage, so you can rest assured even when you're away.
*Available features may vary depending on the equipment installation.
*You will need to install a compatible water heater and remote control in your family's home and connect your smartphone to this app.

●Error Check Screen
Even if your water heater suddenly malfunctions or an error occurs, you can resolve the issue with the app.
