Robo-Tank v5.0 Screenshots and Flowchart - Ideas Needed

[Skwerl77]

I guess what I'm asking is what would be more accurate: getting my solution to exactly 77 and telling the controller it's at 77 (either manually or with a temp probe), or just leaving the solution at room temp, and entering that into the controller instead? Like I said I'm ignorant as to how that all works, I'm definitely no chemist! I don't know if the solution NEEDS to be at 77 for accuracy, or if the controller can compensate for all that for me. I would have to say, during winter, that the room temp would be about 68, so almost 10 degrees different than what the bottle says it should be..
It would be nice to just leave it at room temp instead of dipping it in hot water and overshooting and waiting for it to cool and dipping the thermometer over and over and cleaning it between solutions etc.
