Rheem EZI SET connects to your Rheem Continuous Flow water heater and wirelessly lets you set the hot water temperature (up to 50°C) to your ideal comfortable temperature. Plus it’s safer if you have small children, allowing you to set a safe temperature to reduce the risk of scalding. And if you’re running a bath, you can set in advance a volume to fill your bath to the level you like, after which Rheem EZI SET will automatically turn off the hot water. Your most often used bath fill temperature/volume setting can be saved as a favourite. Up to 3 favourites can be saved, for yourself and for your children if desired. There are voice prompts to assist you programming your hot water and voice warnings should you not provide an instruction or complete an operation, to avoid accidents such as overfilling of a bath. Up to 10 smartphones in your home can download and use Rheem EZI SET (although only one can be in control at any one time for safety reasons). Rheem EZI SET uses your home Wi-Fi network to communicate, for superior signal strength and security. The Rheem EZI SET module is easily fitted into your Rheem Continuous Flow water heater by a qualified Plumber (compatible models only), and the PLT device plugs into your home modem/router. Once you’ve completed the installation in your home water heater, simply download the free Rheem EZI SET app and you can enjoy the full programming capability of Rheem EZI SET . Should your Rheem water heater experience a problem, Rheem EziSET will show the Rheem Service contact phone number and the water heater’s error code on your smartphone screen, to assist in resolving the issue as quickly as possible. Rheem EZI SET can operate on Android Version 4.0.3 or later.
