(7) Fixing of Operation as Exclusive Cooling Unit (b7)
This function is utilized when exclusive cooling operation is required.
This function invalidates the heating operation and the automatic COOL/HEAT operation, as the
operation of exclusive cooling unit.
(8) Automatic COOL/HEAT Operation (b8)
This function is utilized to change cooling and heating operation automatically (the same operation
mode for indoor units in the same refrigerant cycle).
This function is invalid when the outdoor unit is cooling-only model or the function of "Fixing of
Operation as Exclusive Cooling Unit" is valid.
(9) Fixing of Fan Speed (b9)
This function is utilized to fix the fan speed.
When this function is valid, the fan speed can not be changed by the wired controller.
(10) Not Prepared (bA)
(11) Cooling Temperature Compensation due to Uneven Heat Load (bb)
This function is utilized to provide the longer cooling operation time than the standard.
When this function is valid, Thermo-ON/OFF is controlled under the lower temperature conditions than
the setting temperature (the indicated value) of the wired controller.

(19) Hi Speed (Except for Hi Speed during Heating Thermo-OFF) (C5)
This function is utilized to increase the fan speed for the sufficient air flow volume. It is recommended
to use when the air flow volume is decreased by using the optional high ceiling installation or etc.
(20) Hi Speed during Heating Thermo-OFF (C6)
This function is utilized to increase the fan speed during heating Thermo-OFF with the function (19).
(The fan speed does not increase during heating Thermo-OFF even if the function (19) is valid.)
(21) Canceling of Enforced 3 Minutes Minimum Operation Time of Compressor (C7)
The compressor operation is enabled for a minimum of 3 minutes when operation is started by the
"Enforce 3 Minutes Minimum Operation Time of Compressor". This function is utilized to cancel
the function "Enforced 3 Minutes Minimum Operation Time of Compressor" (Enforced 3 Minutes
Compressor Guard).
NOTE:
The compressor operation is stopped immediately as following conditions.
● The protection device is activated.
● The operation stop button is pressed.
