CONFIGURATION OF THE FANS
1: Outer contact (the push button on the console acts as a forced stop)
2: Internal timer (the push button on the console acts as priority forced stop and the
outer contact as forced start)
1: One speed
10: Variation of the rotation speed with increase of the speed
via an increase in cooling control.
11: Variation of the rotation speed with increase of the speed
via an increase in heating control.
12: Variation of the rotation speed via cooling and heating control.
13: Variation of the rotation speed with decrease of the speed via an
increase in dehumidification control.
14: Manual variation of the fan rotation speed.
15: Variation of the rotation speed with pressure increase on the raised floor.
16: Variation of the rotation speed depending on the temperature difference (return/
supply air)
