If you insist. I will keep the 180, after all it is less work to keep it in there. I'll adjust the controller to 198 or so. But I have to ask... why do they make 160's if the temp won't go down that far?
Run whichever one you want. I'm just throwin facts out there. Once more. Thermostats open at the given temperature at which they are rated. That has nothing to do with "how hot" the system runs, only at "what temperature" the thermostat opens. A 160 thermostat would basically be open pretty much all the time. The heater probably won't function correctly. Instead of bouncing this back at me, you could have done some quick research and confirmed everything I've said is right. Like I said, I don't care what you run, the bad info you're laying down needed to be corrected. Nothing personal. It was simply incorrect.
And temperatures CAN go down "that far" IF the rest of the cooling system is capable of getting there......but the thermostat will not make it happen. That's a function of the rest of the cooling system.
