Thanks for the help. It does appear I have a Chronotherm II or III. I'm
heading of to work so haven't been able to study the attachment in
depth...but at first glance I didn't see a way to change the temperature
control to be more than 1degree. In the intro of the manual it says

"Temperature control program maintains temperature within 1degree F of
setpoint"

....well I don't need it to maintain 1 degree....2 or 3 is OK with me. So
I'll study it more this afternoon. Does anyone know offhand if the Chron II
or III can change that setting?

Thanks for the help.
