Hello Edwardvan00, The RWM200 Wireless Module allows you to connect your compatible Rinnai water heater to the Rinnai Central app for additional control and convenience. The RX199i does not include a built-in recirculation pump, so additional equipment is required to enable hot water recirculation. Options may include an external recirculation pump or Rinnai's internal recirculation conversion kit (RX2RXPCK). Depending on your home's plumbing configuration, a thermal crossover valve may also be necessary if a dedicated recirculation return line is not present. Once a compatible recirculation system is installed, the RWM200 can provide scheduling capabilities to help reduce the wait for hot water at your fixtures. We recommend consulting a licensed installation professional to evaluate your plumbing configuration and determine the appropriate equipment for your desired recirculation setup.
Hello Jessie, Yes, the Wi-Fi module allows you to connect to your water heater through the Rinnai Central™ app for greater control and convenience. Depending on your water heater's available features, you can remotely adjust the temperature, manage recirculation schedules, activate vacation mode, and access other settings.
Hello Dryguy, No, the RWM200 Wireless Module can only be paired with one Rinnai tankless water heater. If you have multiple water heaters that you would like to connect using the RWM200, each water heater would require its own compatible wireless module.
Hello Jp00, The RWM200 Wireless Module is compatible with select Rinnai tankless water heater series, including RU, CU, RSC, RX, RXP, CX, and CXP models.
