Typical Rinnai with a frustrating setup and worthless instructions. However, perseverance pays off and once set up it works very well.

The Control module in the kit was defective, but after calling Rinnai technical support, they sent me a new module that works. So now everything is working well and i am pleased.

Horrible product, Horrible setup, In todays "Internet of Things” and connective world this is a product that fits the landscape that existed 10 years ago. This product coupled with they horribly executed app results in a very bad experience.

I read the very negative reviews on this but still decided to give it a try. Franky I can understand those reviews. The wifi module is very frustrating to set up. There are 3 different sets of instructions and none portray how it really goes. I had 2 failed setups but pure persistence finally lead to the lights flashing the correct colors and the system working. In the end the recirc system works well using the button or the programable schedule on the app (which, near as I can tell is a wholly unadvertised feature). Frustrating to set up but works well. Ive had no problems with the wifi dropping offline or failing to properly reboot after a power outage (some people complained about that).

WiFi is easy to self-install on water heater and pair to home wireless. App is not very good. Get the instructions from Rinnai website for your specific model. The included instructions probably won't apply. The pump works well but the included instructions (dated 2016) and the instructions provided on the Rinnai website (dated 2018) do not agree. Make sure water cannot backflow into the return line. There is a check valve in the pump and following the included instructions allows the check valve to do this because the cold water inlet is attached after the pump. The downloadable instructions show the cold inlet attached ahead of the pump and should include a check valve in the return line between. Button works well. Water heater could control water temp better during and immediately after pump operation. Pump was self installed. Reasonable plumbing skills are needed.

The Rinnai Control-R module itself is terribly unreliable. After installation we continued to have many problems. Rinnai customer service could not address it. Eventually we had to have our plumber come back to remove it and put in a wired controller. Because this accessory requires a working Rinnai Control-R module to operate, I would not recommend it at all.If you want WiFi control of your tankless water heater, go with something other than Rinnai. If you are having a Rinnai installed, I recommend you just stick to a wired thermostat/controller.
