What is typical cycling of tankless unit in closed-loop system
Full disclosure, I'm that guy; the one that is hell-bent DIY. I also saw the other posts lamenting the use of Takagi units by amateurs...guess what, I used a Takagi 😊 So, for those that are still reading, here is my situation. The unit comes on as it should when the pump begins to circulate the water, outlet temp rapidly builds to 120 F (or whatever I set it at), and as the inlet temp reaches approx 92 F the unit shuts down and does not come back on until inlet and outlet temps drop to around 85 F. I've never had a tankless before, but shouldn't it run continuously, as long as the circulator pump is on? Its not showing any error codes, so I am rather stumped.
