Economy Mode Information
After the room is heated initially, the air temperature
may be dropped to a lower level without affecting
comfort. The Economy Mode reduces the
temperature by 2 ºF, 30 minutes after the room
temperature setting is reached. After another 30
minutes, it reduces the temperature setting by another
2 ºF, effectively saving energy. The room temperature
setting will drop up to a total of 4 ºF.
The Economy Mode will not operate if the heater is
under capacity for the room size.
