Rinnai® creates innovative solutions that enhance the way people live. And with the introduction of the Rinnai® Control-R™ Wireless Module and mobile app for Rinnai® Tankless Water Heaters, we're taking control and flexibility to a new level. With Wi-Fi connectivity, new and existing Rinnai® Residential and Commercial Tankless Water Heaters (2006 and newer) can be remotely monitored and controlled via smart devices. 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 from your smart phone or tablet.
