Okay, but why does my hot water either stay at the temp I set it to ie 46 degrees if I leave the hot water on, and then if I turn it off then it just continues to drop endlessly to 0. To get the hot water to kick in and heat back up if it drops a bit, do I need to leave the hot water on or turn it off? Sorry if that’s not clear but basically my water either stays at the set temp all the time or the only other setting I’ve found is to turn the water off but then it never heats up and will drop to 0. What I want is a middle ground where it heats up to say 46 and then drops as the tank gets cooler over several hours and then when it gets to say 26 I want it to kick in a heat back up to 46. I can’t figure out how to set this or whether I need to leave the DHW powered on in the app or switch it off in the app? Either way that never happens.

Hi, how can I tell if the pump is working on the heating or the hot water? I was told that the hot water will stay hot in the tank and when I use it, cold water will flow in and when it drops to a certain temp (don’t know what temp) it’ll kick in and heat the water up. If I have the 3 lines on, my system seems to be heating the water 24/7 and it’s costing a fortune. If I turn off the 3 lines then the water will drop endlessly and was 8 degrees yesterday. I want it to run when it only heats up once it drops to a certain temp but I can’t figure out how to set that as it’s either heating 24/7 or not heating at all. Any help please? TIA.
