I'm getting ready to purchase the parts for a solar heating system, but there is something that confuses me. I think I'm misunderstanding something.
I'm looking at the Hayward Aquasolar TC system. Per my understanding, there are two temperature sensors. One of the sensors is monitoring the pool water temperature. The other is monitoring the temp inside the solar collector, right? I thought the collectors were supposed to drain when they weren't in use. Is the sensor just checking the air temperature inside the solar collector? Seems like the collectors would heat up very quickly when there is no water in them, but cool quickly once the water starts flowing...Can someone clear this up for me? Thanks.
