Make the following field settings so that they correspond with the
actual installation setup and with the needs of the user:
▪ Ceiling height
▪ Static pressure
▪ Air volume when thermostat control is OFF
▪ Time to clean air filter
▪ Thermostat sensor selection
▪ Differential for automatic changeover
▪ Auto-restart after power failure
INFORMATION
▪ The fan speed of the indoor unit is preset to ensure the
standard external static pressure.
▪ To set a higher or lower external static pressure, reset
the initial setting with the user interface.
Setting: Ceiling height
This setting must correspond with the actual distance to the floor,
capacity class and air flow directions.
If the distance to the floor is (m) Then

3.0<x≤3.5 03
Setting: Static pressure
Change the value number (—) in accordance with the external static
pressure of the duct to be connected as in the table below. See
technical documentation for details.

Field settings are defined as follows:
•
M : Mode number – First number : for group of units – Number between brackets : for individual unit
• SW : Setting number
• —: Value number
•
: Default
(2)
Fan speed:
•
LL : Low fan speed (set during thermostat OFF)
• L : Low fan speed (set by the user interface)
• 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 : The fan is OFF, but runs for a short time every 6 minutes to detect the room temperature by LL (Monitoring 1) or by L
(Monitoring 2).
