Installed on my current pool water heater and still not working. Looking at the specification and manually measuring voltage when heating the device and it is not producing enough millivolt?
Q313:
Normal Range: 600 to 750 mV.
Lowest Acceptable: 540 mV.
I have measured maximum 200 mV with heater gun.
