My Triton 400K BTU heater is not getting as hot as it used to.
I took measurements with a thermocouple years back when it was new, and either the "POOL" or "SPA" setting would get me 106F. No longer.
I've the schematic which I can read well enough. I am just trying to decide what "POT 1" or "POT 2" I need to change.
I suppose I could remove the potentiometer and measure it, take a SWAG and try a new one.
How-evah, I'd rather nail it the first time.
What the what? Even if I knew what kind of sensor it is (I would GUESS that it is a thermistor?) Sheesh. I seem to be answering my own questions. A thermistor resistance gets LESS as the temp GOES UP.
So, I'd guess I need to add a resistor in series with one of the pots, as the circuit will think the temp is lower when the resistance is higher? Looks like 40K or 50K ohms would do the trick?
