User's Guide
Introduction
The LX Series Unit Ventilator Controller (UVC) seamlessly integrates into a
L
ON
W
ORKS
® network for the control of almost any Unit Ventilator Controller due
to its wide range of output types and L
ON
M
ARK
® certification.
The LX Series Unit Ventilator Controller controls the following equipment:
•
up to four stages of mechanical heating or cooling
•
modulating heating or cooling valves
•
reversing valves for application requiring a heat pump
•
floating valves for heating or cooling
•
unit ventilator with or without an economizer
•
up to three fan speeds or variable speed fans
•
humidifier and dehumidifier
•
an economizer that requires analog, digital, or Pulse Width Modulation (PWM)
control signals
The UVC has five digital outputs supplying 1.0 ampere at 24 VAC. These outputs
produce digital or PWM signals.
There are also two tri-mode analog outputs on the circuit board. These outputs
provide the following signals:
•
linear signals over a 0 to 10 VDC range
•
10 VDC digital or PWM signals
•
digital signals of 60 mA at 12 VDC
The controller has six inputs, each capable of one of 21 possible input types. Inputs
have 12-bit resolution and are configured completely by software.
For easy maintenance and installation, the controller is equipped with plug-in
connectors that accept flat cable or wires. The controller uses a TP/FT-10 78 kbps
network configuration.
The information in this guide helps you to set up the UVC, understand the
operation of the UVC, and troubleshoot problems of the device. Information is
organized to follow the UVC configuration wizard menu.
