Dr. Dendrostein has left the building. Thank you very much. .....thank you very much. ....I found the schematic that I posted in a discussion on the Neptune Forums. It seems to be for the JBJ Arctica 1/5 HP which is the same as the OP’s.

This worked great on JBJ Arctica 1/5 . Push down firmly on top middle of controller before removing case so you can remove and disconnect the controller. Pulled wires 1 and 3 out of 4 pin connector and shrunk wrapped them together. Unit powered up immediately and has been running for an hour. Wifi enabled Inkbird arrives tomorrow. Will drop the Inkbird probe in the sump, plug the chiller into the COOLING outlet and set to TS = 76, CD = 2, PT = 3, which is super simple in the app that now controls and monitors my JBJ Arctica chiller via my iPhone.
