Sorry Moderators. I don't mean to make this an issue or to have it go to the China Shop. I'm just trying to clarify the information, as in my prior position of Research and Development for AutoPilot, I had to cut apart other systems to see what they do. They do not have a temperature sensor, in spite of showing the water temperature.
They also show the salinity level, but is there a salinity meter?
*the answer is no.

Which leads back to my initial response of being able to compensate somewhat by increasing the salt level to the upper range of their recommended salt level.
