Pentair Mastertemp 400 question
This heater is combined with Pentair EasyTouch control panel. The temperature on the control panel when in SPA mode, heater running is much higher than actual Pentair Mastertemp reading. I set max temp on unit to 104, also set EasyTouch to 104. But after running for 30-45 mins, the SPA temp on EasyTouch gets to 110-115F. Of course the heater shuts off at 104 and thus stops the heating process. At this point, the actual SPA water temp is about 90.
I calibrated the SPA temp down by 9 degrees on EasyTouch but this duck tape fix is not the solution.
Where is the heater reading its temperature? I have changed the two attached temp sensors before but maybe the one attached to the inlet pipe running into heater has gone bad? Also not sure if the heater receives its reading from this sensor or it has its own internal sensor?
ALSO...after about an hour, the heater shuts off completely but just before shows Service Heater light. Pulled the front panel of heater and no LED light on interior control panel, nor any error codes on the touchpad panel.
Thanks for your help!
