73... Had a brief power outage yesterday and apparently my chiller was feeling underutilized, so it reset itself to 73... Didn't realize it until this morning. Mr Chiller is now sitting in a corner on a time out...
The Apex claims that my tank never got to 78 for the last few weeks. I have 2 little fans that kick in, blowing the air across the dt surface, when temp is above 77.3. The chiller is in the shed
