LX Series Variable Air Volume (VAV)/Variable Air Volume and Temperature (VVT)Controllers Product Bulletin1The LX Series VAV/VVT controllers use the latest technology to provide you with more flexibility and reliability of control. The LX-VAVLF-1, LX-VAVLN-1, and LX-VVTLF-1 controllers are designed to meet the requirements of single duct VAV or VVT applications.The LX VAV/VVT controllers are based on LONWORKS® technology for interoperability and peer-to-peer communication between controllers without any intermediary, but also integrate seamlessly into the Facility Explorer system. Figure 1: LX VAV ControllerTable 1: Features and BenefitsFeaturesBenefitsConfigurable SoftwareFeatures FX Workbench compatible wizards, which provide 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 HardwareAllows you to use any commercially available thermistor type (100 ohm to 10 k ohm) 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 OptionsPerforms 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.LX Series Variable Air Volume (VAV)/Variable Air Volume and Temperature (VVT) ControllersProduct BulletinCode No. LIT-12011495Issued June 22, 2009LX Series Variable Air Volume (VAV)/Variable Air Volume and Temperature (VVT) Controllers Product Bulletin2LX VAV/VVT Controller OverviewThe LX Controller line offers three VAV/VVT controllers: LX-VAVLF-1, LX-VAVLN-1, and LX-VVTLF-1. Each controller has an integrated brushless constant torque actuator, which has a longer life expectancy than standard brushed motors. The 16-bit analog-digital converter provides high accuracy input and flow pressure sensor readings and allows for precise VAV balancing.The LX VAV/VVT controller line features expanded Input/Output (I/O) capability with four universal (analog-digital) inputs, four digital outputs, two universal control outputs, and six network outputs that allow you to simultaneously control eight instances of any type of Heating, Ventilating, and Air Conditioning (HVAC) equipment, including duct heaters, fans, multi-stage heaters, coolers, analog and floating valve actuators, and lights.The network outputs are bound to the physical outputs of other controllers on the network. The universal inputs similarly allow for the connection of any HVAC equipment or peripheral. The controller dynamically adapts its sequence of operations based on the connected equipment without any need for user intervention. Link spare I/O points on the controller to other controllers on the network allowing for efficient control of devices that are close to the LX VAV/VVT controller.Figure2 shows the dimensions for the LX-VAVLF and LX-VVTLF controllers. Figure3 shows the dimensions for the LX-VAVLN controller.
