Output Wiring
Before connecting an output device (actuator, relay, etc.) to the controller, refer to the datasheet and installation
guide of the equipment manufacturer.
£ For a wire length less than 75’ (23m) long, either a shielded or unshielded 18AWG wire may be used.
£ For a wire length up to 200’ (61m) long, a shielded 18AWG wire is recommended.
£ The shield of the wire should be grounded on the controller side and the shield length should be kept as short
as possible.
£ For relay outputs (DOx); select appropriately-sized wiring suitable to the current load.

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.
