Unofficial Rheem Eziset Protocol Documentation

These pages seek to document the Rheem Eziset Protocol.

The Rheem Eziset is a device used to control the hotwater temperatures of certain Rheem Hot Water Systems. This device appears to be a local variant only available in Australia for now.

The device is made available to trades via trade wholesalers. Residential customers may purchase these devices from plumbing wholesalers by implying that they are a tradesman and quoting the following Rheem Product/ Part Code: 052310. The trade price is around AU$300 but your results may vary.

Please note that while Rheem officially calls this device the Rheem EZiSET Kit - wholesalers have listed this device under various other names. The author purchased this device under the Rheem Smartec Communicator name.
