If you have another one, or can get one, the replacement is a lot easier than the actuator valvesSorry to hear that your aqaulink is giving you more trouble
. I saw this yesterday, but titanuimboy's response was so good that I had nothing to add (WELCOME to the forum Titaniumboy!!!
- great first post!!). What I really liked was the suggestion to switch out 2 of the sensors - it's quick, dirty and easy. Open the box, remove the 3 screws to remove the cover plate. On the left side is the area to run all of the wires through (actuators and thermistors) - follow the 3 beige wires to where they are attached - switch out the solar and the air and see what the unit thinks the air temp is. (you'll need a very small screwdriver to disconnect and reconnect the wires - I'd advise putting a piece of tape on the solar wire so you don't get them confused while changing them around) If, as suspected, the solar thermistor is bad, pull the wire out of the bottom of the unit and trace it back to the thermistor itself - you've now found it. Once you have a replacement thermistor and know where it goes, you'll see just how easy the change-out is going to be. It's held in place by a clamp, loosen the clamp enough to remove the bad one and simply put the new one in it's place, run the wire back to the unit and attach the new wire where the old one was -- simplicity itself!
Just be sure that the solar isn't under pressure when you make the change-out.
I can assure you that this will be easier than the actuator - waste
