Only one Zehnder EDT2 Wall-Mounted Touchscreen User Controller can be connected to the CLD-283 controller.
It is important to keep the data transfer cable away from power cables and sources that produce regular power outages
(contactors, relays, frequency inverters, etc.) to avoid interference that could affect the quality of data transmission.
Zehnder EDT2 side:
■
Connect the data wires (twisted pair) to terminals (B) and (A), and the shielding to (N) of port P2 of the controller.
■
Connect the power leads to terminals (+24) and (N).
Ventilation unit side:
