Extract air fan speed may be configured as follows:
• “EAF Ctrl.” – setting extract air fan speed or pressure (depending on the configuration) or percentage deviation setting -20+20% of the supply air
fan setting. Default value: 0%
Where control is performed by pressure transmitters, the minimum (min_0V) and maximum (max_10V) limits of the pressure transmitter input are
set (by “FLEX” remote control):
„Meniu“ > “Additional” > “Service” .“PSI“
• “min_0V” – Pa
• “max_10V” –, Pa
Where control is performed by the CO2 converter, the maximum permissible CO2 value is set; if it is exceeded, the supply and extract air flow is
increased (by “FLEX”)
Meniu>>Additonal>Add.Func.>CO2
•EAF Low – the extract fan speed is set at the selected speed “low”, %, Pa.
•EAF Midd– the extract fan speed is set at the selected speed “middle”, %, Pa.
•EAF High– the extract fan speed is set at the selected speed “high”, %, Pa.
Maximum/“boost” mode adjustment by “Stouch” remote control:
Maximum/“boost” speed is protected by a timer which can be easily changed by running the maximum fan speed (boost). Maximum speed is activated
by the fast button. When the maximum set fan speed (boost) time is over, the previous speed is automatically reset.
Where Stouch remote control is used, all settings made by Flex remote control become inactive. All settings of this function must
be made by Stouch remote control.

adjusted by touching B4 and B6.
Connection of a functional node to a ventilation unit:
To maintain the constant pressure in the air transportation systems (supply and extract air), it is necessary to use two pressure transmitters (1141).
They are ordered individually.
The supply air pressure transmitter (transmitter 1) is connected:
23 – power supply to the transmitter. 24V DC
24 – input from the transmitter, 0–10V DC
24 – power supply to the transmitter, GND
The extract air pressure transmitter (transmitter 2) is connected:
26 – power supply to the transmitter. 24V DC
27 – input from the transmitter, 0–10V DC
28 – power supply to the transmitter, GND
Pressure transmitters are used only when connected by Flex remote control.
