I just recently replaced my really old aqualogic to an also old but newer prologic.

My setup is like this:
My Pool/Spa are connected. My spa has an overflow to my pool. I have a caretaker99 in ground cleaning system. This turns on my spa overflow every 10 minutes or so for a minute.
My spa has its own filter and pump. My pool has its own filter and pump.

I have a water temp sensor for my pool line. I have a water temp sensor for my spa line. I made it a dual system since they are controlled by separate pumps and filters. Is this correct?
The display is saying the circuit is open for the spa sensor.
The connections on the prologic board have one pool/spa sensor connection. Where do i plug in the spa temp sensor on the board?
