The LN Series Variable Air Volume (VAV) and Variable Volume Temperature (VVT) controller line controls various types of Heating, Ventilating, and Air Conditioning (HVAC) equipment. The controllers are based on LONWORKS® technology for peer-to-peer communication between controllers and are LONMARK® network certified. Models with a built-in damper actuator (LN-VAVLF, LN-VVTLF, LN-VAVCF) mount onto an air duct or within a panel.

1. Visit the Johnson Controls® intranet site
(www.my.johnsoncontrols.com) and download the
latest version of the plug-in installation setup. You
can also contact your Johnson Controls
representative to obtain the file.
2. Run the installation setup to install the device
plug-in and latest version of the .xif and .apb files.
The .xif and .apb files install in the
C:\LONWORKS\Import\JCI folder.
3. Register the plug-in in the network database. This
step creates a new device template that you use to
commission your device.
4. Add and commission the device with LN-Builder 3
using the proper device template and .apb file.
IMPORTANT: Downloading an improper .apb file
into the device may damage the Neuron® chip in
your controller. The controller may become
unusable.
Neuron ID and Service Pin
To commission a device and add it to a LONWORKS

To mount on a wall using double-sided tape, first apply
the tape to the back of the receiver and then stick the
receiver onto the desired wall or ceiling location.
Wall or Ceiling Mount with Screws
To mount the wireless receiver with screws:
1. Separate the front and back plates on the receiver
to open it.
2. Use the mounting holes on the back plate to mark
the wall or ceiling location.
3. Drill the holes.
4. Clean the holes, insert wall anchors, and fasten the
back plate with the screws.
