LN Series Variable Air Volume (VAV) and Variable Air
Volume and Temperature (VVT) Controllers
Code No. LIT-12011298
Product Bulletin Issued May 16, 2012
LN-VAVLF-2, LN-VVTLF-2, LN-VAVLN-2 Supersedes October 4, 2010
The LN Series LN-VAVLF-2, LN-VAVLN-2, and
LN-VVTLF-2 controllers use the latest technology to
provide you with more flexibility and reliability of
control. The LN VAV/VVT controllers are designed to
meet the requirements of single duct Variable Air
Volume (VAV) or Variable Air Volume and Temperature
(VVT) applications.
The LN-VAVLF-2, LN-VAVLN-2, and LN-VVTLF-2
controllers are based on LONWORKS® technology for
interoperability and peer-to-peer communication
between controllers without any intermediary, but also
integrate seamlessly into the Metasys® system.

Table 1: Features and Benefits
Feature Benefit
Configurable Software Features an LNS plug-in which provides the ability to easily configure inputs, outputs, and
sequence options. Configured device complies with LONMARK® Space Comfort Control (SCC)
profile for interoperability with other LONMARK devices.
Robust Hardware Allows you to use any commercially available thermistor type (100 ohms to 100k ohms) and
setpoint potentiometer type. Features an extremely accurate onboard airflow sensor for
pressure independent single duct VAV applications. The controller can read differential
pressure as small as 0.04 milli-inches.
Powerful Control Options Perform Demand Control Ventilation based on CO2 sensor readings to ensure high indoor air
quality in an efficient manner. Provides you with the ability to link VAV occupancy status with
local lighting control.
Wireless Functionality Features an optional EnOcean® wireless receiver (LN-WMOD315-0 or LN-WMOD868-0) that
you can use with a variety of wireless sensors and switches. The wireless receiver
(LN-WMODxxx-0) supports up to 14 wireless inputs, which allow you to create wire-free
installations.
