I have an older clormatic CM601 with a cell that is a little over 4 years old, this is the end of the 5th season on it.
I am getting a service code of 121, low current in reverse direction to cell. I looked at the cell, and do not see any evidence of scaling. I had a service man come out for a few other issues I was having, and he said that this code was evidence that the circuit board in the controller is going bad. Most of what I read online indicates my cell is going bed.
I am thinking that regardless of whether the cell is good or bad I should look at replacing the entire system to something newer. I would like recommendations. I will be doing the installation myself so as close to drop in as possible is a positive for me. Could somebody give me a recommendation as to which unit I should purchase? I have a 19,000 gallon vinyl pool, in ground.
I realize that this question is open to all types of personal preference and I have read all the threads on SWG recommendations in the forum, would just like to update everybody’s two cents. It seems like the two I see recommended the most are Aquarite and Compupool. I use salt test strips so accuracy of the salt reading is not that important to me, but the accuracy of the water temperature is, because I have a solar heater tied in to that. Other than that ease of installation is the most critical factor to me.
