The calitemp sensor has functioned very well, up until the last few days.
Now I find it varying by as much as 2 C. When I compensate calibration per my IR gun, it does not stay calibrated. It seems to keep drifting higher in temperature than actually exists in the water loop.
Since I run my pumps on delta T, I first started noticing the pump flow higher than expected, and saw the calitemp sensor seemed to be reading high. Confirmation with IR gun concluded as much, whereas previously the sensor and my IR gun agreed pretty closely.
Is there a fix for this, or is the sensor broken?
Thanks.
