TIP
Wait 24 hours before making a new setting, so that the
room temperature has time to stabilise.
If it is cold outdoors and the room temperature is too low,
increase the curve slope by one increment.
If it is cold outdoors and the room temperature is too high,
lower the curve slope by one increment.
If it is warm outdoors and the room temperature is too low,
increase the curve offset by one increment.
If it is warm outdoors and the room temperature is too high,
lower the curve offset by one increment.
