I have a newly installed IAqualink 2.0 system and i noticed a weird thing: i have it on a maintain heat setting (basically it samples the water every 3 hrs and if the temp is lower than what we set it at, the heater kicks on). The water temperature showing on the iAqualink app is all over the place. The heater hasnt been on since 7am (set at 86) and the water temp at 1 point will read 93 degrees....then i check again and its 87. The pool is in the desert but this time of year its 83 during the day, 68 at night. Its impoddible the water has heated up to 90 degrees, or even warmer than the 86 we set it at....im not sure if i have a bad sensor or if the sensor is installed in the wrong place? Maybe the sun is hitting it? Is there any other way the water could be heating up by the equipment right before it hits the sensor, throwing off false readings? Again, the system is brand new...in fact all of the equipment and (heater, pump filter etc) is new!
