tions are to restrict the operations of the remote control switch only. If operation is preformed from the centralized con-
troller, the command from the centralized controller is adopted.
F8 - Lock Function for Operation Mode Selection
F9 - Lock Function for Temperature Setting
FA - Lock Function for Fan Speed Selection
Fb - Lock Function for Swing Louver Operation
FC - Cooling Lower Limit for Setting Temperature
This function is utilized to limit the lowest setting temperature for FAN/COOL/DRY operations.
When this function is valid, it provides the appropriate cooling operation and energy saving.
The setting conditions and the minimum setting temperature for cooling are as follows:
• Example:
Factory-Setting: "00"
(Lower limit 19+0=19 ºC)
Setting condition: "06"
(Lower limit 19+6=29 ºC)
