It is a old Teledyne Laars heater. 30 years +. Works great. No it will not activate due to automated heater bypass. No water pressure present .In addition I added a flow switch in case the pressure switch failed in the heater.It was recommended here in the forum.

I am still getting some passive heating that has got me in a quandary.Here are some shots of the flow path. NOTE: The top check for the automated heater bypass was rendered unchecked(removed flap) as I found it to be superfluous. Also keep in mind none of the equiptment has changed but the...

Well... perhaps I did overlook something. I did a voltage/ohm test and found my water Jandy temp sensor was high by 3f degrees. I believe that's ,at least, part of the problem. Assuming ,can throw off your troubleshooting.

My pool is still heating on its own . Ambient air temp yesterday was 78F degrees and the pool water temp rose to 88F degrees after starting at 81 F and running for 5 hours. A couple of things to note are: 1) With the solar valve off and the pump running, the return check appears to be closed...

The pool is 27 years old. The pool solar is about 7 years old. I don't recall it ever gaining that much heat relative to the ambient air temperature. I wouldn't mind so much but it does require a higher percentage of SWG on-time. Yes, I will keep that $60 check valve as a spare since it...

Replaced the check valve. But no change. In addition to the solar acuator valve being in the off position I closed the manual valve just behind it to make sure the solar valve wasn't leaking. I am at a loss to know why my pool is heating to 84 F degree with an air temp average temperature...

Thanks so much for you reply. I'll replace that check and see what happens.

This just started to happen. With the conventional pool heater off and the solar heater off the pool temperature is rising much higher than normal. Today it rose to 83 degrees with the air temp at 75 degrees.The pool temp is normally always less than the air temperature with no heat in use. The...

Matt, you are absolutely correct about that. Thanks for the suggestion. And I will consider that adjustment on that JVA. I know the iAuqualink board has a cool-down mode on-off dip switch for that very reason. That is, under normal circumstances. In this case, although that cool down mode will...
