Pre-heat
The appliance may operate up to one hour before the
programmed ON time in order to allow the room to
reach the desired temperature by the programmed
ON time. The pre-heat time (how long before the
programmed ON time that the appliance will provide
heat) is determined by the difference between the
temperature setting and the room temperature one
hour before the programmed ON time.
