EXTERNAL INPUT/OUTPUT AND FUNCTION SETTING
5.4.2.2 Description of Function Selection Item
(1) Cancellation of Heating Temperature Compensation due to Uneven Heat Load (b1)
This function is utilized when the setting temperature of the wired controller and the inlet air
temperature of the indoor unit are required to be equal.
This is useful when the inlet air thermistor is removed to the outside of the indoor unit.

(2) Circulator Function during Heating Thermo-OFF (b2)
In the standard factory setting, the air flow volume changes to "LOW" automatically to prevent a cold
draft during heating Thermo-OFF.
Therefore, the air flow might not be distributed uniformly in the room depending on the installation
location of the air conditioner or room structure. In such case, it is recommended to utilize this
function.
The function keeps the air flow volume during Thermo-OFF at the same level as during Thermo-ON.
The air flow in the room is kept at the same level as during Thermo-ON so the room temperature is
uniformly-distributed. If using the air conditioner with auto swing function, the auto swing function is
activated even during heating Thermo-OFF.
NOTE:
The temperature sensibility and demands for air flow distribution differ depending on the person. It is
therefore recommended to discuss these matters with customers thoroughly and then install the unit
accordingly.
(3) Not Prepared (b3)
(4) Change of Filter Cleaning Time (b4)
The period before filter sign indication is set according to indoor unit model before shipment.
The filter sign ("FLTR" on wired controller) is indicated according to the filter cleaning time (Factory
Setting). However, this filter cleaning time can be changed depending on the condition of the filter as
shown in the table below.

NOTE:
While "Control by External Input" is valid, the filter sign displays "No Indication" if the external input is
disconnected.
(5) Fixing of Operation Mode (b5)
This function is utilized when the operation mode is not required to be changed.
When this function is valid, the set operation mode cannot be changed by the wired controller.
(6) Fixing of Setting Temperature (b6)
This function is utilized when setting temperature is not required to be changed.
When this function is valid, the setting temperature cannot be changed by the wired controller.
