Coolant temperature should be in the middle of range and be relatively stable.
210 is very much in the middle of the range. 230 is pushing it and 250 you'll be lucky if its not boiling (depends on pressure and mix).
Running too cold means the cylinder walls are on the cold side and so is the oil. I like to see at least 190 once its warmed up. Sometimes in winter that's tough with a 180 thermostat.
