Connection of a functional node to a ventilation unit:
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
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.
Pressure transmitters are used only when connected by Flex remote control.
The use of forced ventilation (“boost”) by a digital input. To activate this function a button or motion sensor (PIR) can be used.
4;5 – connection of an external button or PIR sensor
To reduce CO2 concentration at the premises the CO2 transmitter must be connected (channel transmitter or installed indoors).
The extract air CO2 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
Presssure transmitters are used only when connected by Flex remote control.
