Configuration

16.1

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

▪ 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)
