Field setting

Make the following field settings so that they correspond with the
actual installation setup and with the needs of the user:
▪ Ceiling height
▪ Decoration panel type
▪ Air flow direction range
▪ Air volume when thermostat control is OFF
▪ Time to clean air filter
▪ Thermostat sensor selection
▪ Thermostat differential changeover (if remote sensor is used)
▪ Differential automatic changeover
▪ Auto-restart after power failure
▪ Function for refrigerant leak detection
INFORMATION
▪ The connection of optional accessories to the indoor
unit might cause changes to some field settings. For
more information, see the installation manual of the
optional accessory.
▪ Following setting are only applicable when using the
BRC1H52* user interface. When using any other user
interface, see the installation manual or service manual
of the user interface.
Setting: Ceiling height
This setting must correspond with the actual distance to the floor,
capacity class and air flow directions.
▪ For 3-way and 4-way airflows (which require an optional blocking
pad kit), see the installation manual of the optional blocking pad
kit.
▪ For all-round airflow, use the table below.
If the distance to the floor is (m)
FXFN50 FXFN71, FXFN112
≤2.7 ≤3.2
2.7<x≤3.0 3.2<x≤3.6
3.0<x≤3.5 3.6<x≤4.2
Setting: Decoration panel type
When installing or changing the decoration panel type, ALWAYS
check if the correct values are set.
If the ... decoration panel is used
Standard or self-cleaning
Design
(1)
Field settings are defined as follows:
• M: Mode number – First number: for group of units – Number between brackets: for individual unit
• SW: Setting number / C1: First code number
• —: Value number / C2: Second code number
• : Default
(2)
Fan speed:
• LL: Low fan speed (set during thermostat OFF)
• L: Low fan speed (set by the user interface)
• H: High fan speed
• Setup volume: The fan speed corresponds to the speed the user has set (low, medium, high) using the fan speed button on the user
interface.
• Monitoring 1, 2, 3: The fan is OFF, but runs for a short time every 6 minutes to detect the room temperature by LL (Monitoring 1), by L
(Monitoring 2) or by H (Monitoring 3).
