Thanks Ajw22. That's what brought me here, it doesn't make sense. Both replacement thermistors were official pentair parts, I'm not sure about the thermal regulator I can check again which one I purchased, although I did do a 120F water test to see if it opens(which it did). Like you said there...

Do you think it's worth taking off the manifold and looking for anything strange going on?

Just checked the board with a 10k resistor. Stayed at 76 for ~30min. Any other ideas?

And I have run the pump at its normal 3100,2600,1850 rpm. Even trying to run it on the overide of 3450 to see if the flow was the issue. It still has the same temp issue. I'll give the board a check and report back.

Appreciate the response. Yea just an in ground Spa about ~100-150ft from the pump/heater. I did look into the thermistor before this finding that it goes from 10k ohms to 5ohms as the temp rises, but hadn't gone out to test it yet. Figured I'd ask here first. I'll head off to home depot for a...

No automation unit. The heater display board itself. Temp set on the heater unit. Spa Temperature was measured at the spa itself with a laser thermometer and a floating thermometer. I'll create a signature now, but its a pretty basic variable pump, filter, heater spa system. Thanks for the...

I have already replaced all sensors and the thermistor twice, so its not those. So the problem is when the heater is not running the temperature of the actual spa and the heater unit are the same(working). As soon as the heater begins running, the spa temperature will begin rising and the...
