I guess it comes down to what you mean by function. I think there is a consensus that SWCG and test strips and other types test have a rather large error of probability in the order of a couple hundred PPM plus or minus.
There is no dedicated sensor to measure water temp on the compupool systems.
A SWCG generates chlorine gas that's it. That's what it's designed to do. Nothing more. I understand you'd expect a correct readout but in the big picture what does it really mean. If the salt level is too high or too low it will give you a separate indication. They don't specify an actual level for the ADD Salt indicator, and if it's OVER Salt it will continue to produce chlorine with the increased salt content. There are actually 2 different readouts the Control Panel LED indicators and the out put display that scrolls messages. I'm more concerned with the Control Panel LED indicators Water Fault/ADD SALT/OVER SALT. Than temp display which isn't an actual measured value or PPM value (both which are calculated through software but which have to make some assumptions that may or may not be true to a users situation).
My cell is a couple months old. I have no visible scale formation. The unit does alternate polarity and I have seen the scale come off when the polarity changes. I also realize my CYA is higher than the recommendation levels, I am slowly working on bringing it down.
I guess I may have lower standards. I'm not concerned with what it's showing as a temp and salt value, as long as its producing chlorine gas in my specified pump run time to meet my pools chlorine usage demand. That is the main concern for my usage of a SWCG.
I'll be the first to admit, I'm lazy. I called got the directions to re-calibrate but it required me to open the system and I like the adage "if it isn't broke don't fix it", it's producing, so....
