I just noticed that my Rheem Heat Pump water heater was no longer following the schedule that I programmed. When I looked in the Rheem Econet App on my iPhone all the schedule settings we set to Energy Savings Mode. I re-entered the schedule but when I switch to “Follow Schedule” and “Save” the settings are again lost. I deleted the app and downloaded what appears to be a newer version, however while it looks different it behaves in the exact same way. This whole things has worked (sort of) for several years - any ideas whats going on?
