Product Description
This document describes the hardware installation procedures for the ECL-VAVS Single Duct Variable Air Volume Controllers.
The Distech Controls Variable Air Volume product line is designed to control and monitor various types of HVAC equipment such as baseboards, single
and multi-stage duct heaters, fans, valves, lights, etc. When connected to a Wireless Receiver, this product line can be used with a variety of wireless
battery-less sensors and switches.
Each controller uses the L

General Installation Requirements
For proper installation and subsequent operation of the device, pay special attention to the following recommendations:
£
It is recommended that the controller(s) be kept at room temperature for at least 24 hours before installation to allow any condensation that may
have accumulated due to low temperature during shipping/storage to evaporate.
£
Upon unpacking, inspect the contents of the carton for shipping damages. Do not install a damaged device.
£
The device is designed to operate under environmental conditions that are specified in its datasheet.
£
Ensure proper ventilation of the device and avoid areas where corroding, deteriorating or explosive vapors, fumes or gases may be present.
£
Record the 12-character Neuron
£
Allow for proper clearance around the device's enclosure and wiring terminals to provide easy access for hardware configuration and maintenance.
£
When installing in an enclosure, select one that provides sufficient surface area to dissipate any heat generated by the device and by any other de-
vices installed in the enclosure. A metal enclosure is preferred. If necessary, provide active cooling for the enclosure.
£
The device's datasheet specifies the power consumption (amount of heat generated), the operating temperature range, and other environmental
conditions the device is designed to operate under.
£
Ensure that all equipment is installed according to local, regional, and national regulations.
£
Do not drop the device or subject it to physical shock.
£
If the device is used and/or installed in a manner not specified by Distech Controls, the functionality and the protection provided by the device may
be impaired.
Any type of modification to any Distech Controls product will void the product's warranty
Before installation of the Wireless Receiver, verify that local communication regulations allow the installation of wireless devices and
available frequencies to be supported in your area. Refer to the Open-to-Wireless™ Application Guide for more information.
Take reasonable precautions to prevent electrostatic discharge to the device when installing, servicing or during operation. Discharge
accumulated static electricity by touching one's hand to a well-grounded object before working with the device.

Controllers with terminal block covers can only be mounted on a flat surface that is sufficiently large to provide space around the installation.
- Page 5 3. Screw the controller onto the VAV box through the controller’s Sliding Grommet. The sliding grommet allows the controller to move back and forth when the VAV box’s damper shaft is off center. Ensure to center the grommet along its travel range and ensure that the screw enters the VAV box at a right angle.
