Field settings
Make the following field settings so that they correspond with the
actual installation setup and with the needs of the user:
▪ Ceiling height
▪ Design decoration panel (if applicable)
▪ Air flow direction
▪ Air volume when thermostat control is OFF
▪ Time to clean air filter
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 air flows (which require an optional blocking
pad kit), see the installation manual of the optional blocking pad
kit.
▪ For all-round air flow, use the table below.
If the distance to the floor is (m)
