Central ventilation units AIR1 RH
• Constant pressure
• External fan control
If "External fan control 0-10 V" is selected using the commissioning assistant (wizard), the other modes will not be avai-
lable.
Ventilation mode
Constant volume flow
The ventilation mode is used to select the different fan control variants. Press the
menu to select the ventilation mode. Press the
air and extract air fans are set for three ventilation stages (reduced, normal, boost) in m³/h in the constant volume flow
mode or in % in the constant speed mode. In the constant pressure mode, the duct pressure is set in Pa. Press the
button to adjust and press the
The following functions can be selected for the ventilation mode:
• Constant volume flow (m³/h)
• Constant speed (%)
• Constant pressure (Pa)
a� Constant volume flow
3 ventilation stages are available:
• Reduced
• Normal
• Boost
Each ventilation stage has two independent settings for the supply and extract air fan.
When "Constant volume flow" is selected, the volume flows can be set in the "fan control" menu separately for the
supply air fan and the extract air fan:
When setting the ventilation stage „minimal", please observe the minimum volume flow� For minimum flow see
table „Technical data", CHAPTER 3�

When "Constant speed" is selected, the volume flows can be set in the "fan control" menu separately for the supply air
fan and the extract air fan.

One ventilation stage is possible:
• Normal
If the ventilation stage reduced or boost is subsequently selected, the ventilation unit will run with the settings for the
ventilation stage normal.
If "Constant pressure" has been selected, the duct pressure can be set using the "fan control" menu. The duct pressure
setpoint is set for the supply air fan. The extract air fan has the same volume flow as the supply air fan.
