Title 24 Compliant - meets California Energy Commission's Title 24 requirements.

Installation Requirements
Choose a central location inside the home or business where the Wi-Fi signal is strong. If the Rinnai Tankless Water Heater is located where the Wi-Fi signal is weak (such as basements or a mechanical room), the module is designed so that wiring can run up to 300 feet (91 m) away from the water heater to ensure a strong Wi-Fi signal (18-22 gauge wire is required).

The module must be installed indoors. Adequate space must surround the module for service and support needs.

Supported Devices
Apple® devices (iPhone, iPad, etc.) running operating system 8.0 or higher.
Android® devices (phones, tablets, etc.) running operating system 4.4 or higher.
BlackBerry® devices are not supported.

802.11N Wi-Fi Network up to 2.4 GHz.
Not compatible with MC-195T-US or MC-100V controllers.

How It Works

The new Control-R™ Wi-Fi Module attaches easily to the Rinnai Tankless Water Heater by a two-wire interface quickly connecting through your Wi-Fi network for monitoring. Once connected and the free Rinnai app is downloaded, the Rinnai Tankless Water Heater can be controlled using your smart phone or tablet.

The free Rinnai App is available from the Apple® Store or Google® Play Store.

If your system has recirculation capability, you can activate recirculation though the use of the Control-R™ Wi-Fi Module, motion sensor or push button for faster hot water.

  • Push Button | Part #: RWMPB01 | Mounted near the point of use, like a kitchen faucet or bathroom sink, and operates the recirculation system.
  • Motion Sensor Part | #: RWMMS01 | Mounted near the point of use and operates the recirculation system with the detection of motion and full-body movement up to 30 feet (9 m).
