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.
