(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.
* The selecting range:
• The reference temperature for set-back operation
• The set-back value
• The setting temperature
(3) Weekly schedule setting
The schedule pattern P1 to P3, local remote control prohibition (P4),
P1 to P3 and P4, and non-timer operation(-) are set for each day.
