(2)Set-back values and setting temperature setting

•Setting the set-back values and setting temperature can be performed only when selecting either "SET BACK" or "SET TEMP" on the user setting screen in the initial setting mode.

•Set-back operation

Set-back operation is a method which reduces the air conditioner running cost by controlling the operation with specified time band for lowered load. In other words the unit operates at a few degrees higher for cooling and a few degrees lower for heating in the specified time band.

EXAMPLE When the reference temperature is 24˚C / 75˚F and the set-back value is set to 2˚C / 4˚F.

•Cooling operation : 24˚C+2˚C=26˚C / 75˚F+4˚F=79˚F

•Heating operation : 24˚C-2˚C=22˚C / 75˚F-4˚F=71˚F

•Setting temperature operation

This operation sets the temperature when timer ON is set to a predesignated temperature regardless of the op- eration mode.
