Tharrison. I don't know when the change was made for the upgraded controls on the tankless water heater..........somewhere after 2014s hit the market and 2015s. There have been issues with controlling water temp. The upgraded model has a controller in the bathroom. Do a search of the forums on tankless water heater....also forums on irv2.com
