Communications Wiring - Distech Controls ECL-VAVS Installation Manual

Subnet Wiring
The subnet is used to connect a range of Allure Series Communicating Sensors:
£ The Allure EC-Smart-Vue Series sensor is a communicating room temperature sensor with backlit display graphical menus and VAV balancing ca-
pabilities.
£
The Allure EC-Smart-Comfort and Allure EC-Smart-Air Communicating Sensors are a range of communicating room temperature sensors.
Connect the Allure Series to the controller's Subnet Port with a standard Category 5e Ethernet patch cable fitted with RJ-45 connectors. Refer to the Net-
work Guide for extensive information and requirements for the connection of the Allure Series. It contains information about network topology and length,
cable type, setting the Subnet ID, etc. It can be downloaded from the Distech Controls' Documentation and Resources Portal. See also the Hardware In-
stallation Guide supplied with the Allure Series.
If you make your own patch cable, see the Allure Series Hardware Installation Guide.
Protect the controller's connector from being pulled on when a cable to the Allure Series is connected. Create a
strain-relief by looping the cable and attaching it to a solid object with a nylon tie so that a tug on the cable will not
pull out the connector on the controller.

Communications Wiring

The recommended cable type for L
larity insensitive and can be laid out in a bus, star, loop or free topology. For loop topology, polarity is important, special care must be taken when con-
necting the L W network to avoid short circuit.
ON ORKS
It is recommended to use the bus topology network configuration for all L
for easy network troubleshooting.
Connect both wires to the LON+ and LON‑ terminals of the controller. If inserting multiple wires in the terminals, ensure to properly twist wires together
prior to inserting them in the terminal connectors.
