I got PentAir SolarTouch controller for my upcoming solar heater and it came with 2 sensors - water and air. The first one is 20' and the second is only 20" - it barely sticks out of the controller, making its placing it very difficult.
Is it supposed to be exposed to the ambient air only, or does it have to be in the sun when the panels are in the sun? I assume the latter, in which can I'm puzzled by manufacturer's decision to make it so short.
