(((((((let's clear up exactly what equipment you have, ok? Since you mentioned a T15 cell I assume you have a Goldline?Hayward Aquarite SWCG hooked up to the Jandy pool automation system?)))))))))))

Correct

((((((((((Please post all your equipment (pumps, filters, automation, how many valve actuators and what they control, heaters, etc.) and we can take it from there.)))))))))

One three-way for skimmer valves 1 and 2.
One three-way valve for center drains.
One Jandy maximum torque actuator valve for suction of pool pump.
One Jandy maximum torque actuator valve for Pool or spa return.
Control sensor on discharge of pool/spa pump.
Control sensor on discharge of spa/ pool return.

((((((((Also post a FULL set of water test results (FC, CC, pH, TA, CH, CYA, salt), how many gallons in your pool,))))

13,000 Gallon Pool.
I had my water tested today to see where I’m at after adding salt acid yesterday.
Chlorine is at zero. 0%
Available chlorine zero, or 0%
Salt 3000 ppm
Hardness 120ppm low, should be (200-400)
Cyanuric acid 45 ppm, good.
Total alkalinity 90 ppm, good.
Ph 7.4, good
Copper zero, good
Iron, zero, good.

I’m going to add a few Chlorine tablets to my skimmer baskets to get my Chlorine levels back up.
I don’t think my control box is kicking on the T Cell to generate chlorine. I know the T-Cell15 works because I had it checked on Tuesday. It pass the test twice.

(((((((Your current water temperature, and if it is pool or a pool/spa combo using the Jandy controller )))))))

Temp is around 78*, Texas weather.

((((((I suspect it is a pool/spa combo since you mentioned a blower) and if so if it is a spillover spa or if they are two separate bodies of water (I suspect the former since I do not believe the Jandy allows separate chlorination settings for pool and spa using an Aqauarite, but I could be wrong and would have to research that further).)))))

Yes. It is a pool-spa combo and spills over from spa to pool.



(((((If you are getting a message about the solar sensor then I would suspect a problem with the Jandy unit and not the SWCG, which could also explain why the jandy is not reporting the proper salt level. What is the readout on the Aquarite indicating? My guess is a circuit board problem on the Jandy since it is giving a spurious error message and also not reporting correct info from the SWCG.)))))))))))))

The Aquarite is indicating a salt percent of 3500ppm inside my house and at the Goldline box by pool equipment. I’m just now getting up to 3000ppm after adding 6 Bags of salt this week. It rained over the weekend while I was out of town.
