I installed it. When I first installed it, I powered it up Sunday afternoon, and red light went solid...no surprise because I had not added salt. I unplugged it, added salt, waited 24 hours, tested it with the Taylor kit, got 3200 ppm reading, and then plugged the cell back in Tuesday (yesterday) morning, light went solid green. I got home yesterday afternoon, and light was solid red. Pump/IC40 are set to run for 4a-10a and 4p-10p.
I have no idea how to read the salt level on the IC40...all I get are lights. I bought the standalone power supply, so none of the communication items work.
