The Apogee SP-110 should be connected to the two poles connector (bellow R2) on the Solar / UV interface.
Connect the Red wire to (+)
Joint the Black and Clear wires and connect them together to (-)
The variable resistor (R2) in your Solar / UV interface is already adjusted to work with the Apogee SP-110 pyranometer. Adjust as done based on Apogee specs which say: The SP-110 is a self-powered, analog sensor with a 0 to 350 mV output
Likely you will not need to do any adjust on R2, however some further calibration may be needed, which most of the times can be done in the software.

Have a great weekend!
Thank you. I nice weekend for you too.
The rainy days will be a great opportunity to check the readings between Pro2 PLUS display and Cumulus.
Your work, when returning to the roof will be easier... soon you will know why.

Rain stopped long enough for me to quickly install the solar/uv board today. Everything appears to be functioning at this time. Will monitor the readings if any sort of software adjustments are necessary.
Also, I messaged the guy to tell him it's working and I noticed he had only sold 2 of the SP-110s. I asked him if he would ship to Europe and he said he would consider it as long as the shipping is paid. I have no idea how much the shipping would be, but if you want a SP-110 he said he was open to the idea of shipping outside the United States, so message him on ebay and see if he'll ship to you if you're interested.
Thanks for all the hard work, Werk, and everyone else.
The sun has set and I still have a reading of 4 W/m2 fluctuating to 6 W/m2. Do I adjust the pot on the board to get 0 W/m2? Or is it more precise to adjust it in software?
