Temp Bias Adjustment On Coal-Trol

Temp Bias Adjustment On Coal-Trol

PostBy: WNYRob On: Mon. Nov. 24, 2014 9:49 am

I have a question about the actual internal programming of the coal trol TS2 thermostat, which will probably turn into what looks like a dumb question. When you are adjusting the temperature bias, I believe every push of the adjustment buttons changes it by .2 degrees. As you are adjusting, the instant the display changes from say 72 to 73 degrees, is the actual temperature adjustment changing from 72.8 to 73, or is there some rounding going on so say you are increasing the bias and as you hit 72.6, the display shows 73?

I believe for the bias adjustment it is a floor operation, not a rounding one. So as you say, it will say 72 until you cross to 73 or better, not something above or at 72.5.

Also, it is not .2 per click. The math works out to something like .145 per click, or something like that. Sometimes it takes 7 presses to bump a whole degree. Other times only 6. It's been a long time since I looked at that area of the code, so don't recall for sure offhand.
