Factory pre-loaded applications allow this controller, straight out of the box, to operate standard VAV equipment with a proven energy-efficient sequence of operation. This eliminates the need for programming. You can select the pre-loaded application using an LN Series Communicating Sensor even before the network has been installed, for rapid deployment or through any LNS® based software tool such as Johnson Controls® LN Builder. The LN -VAV04060-0 controller is fully programmable allowing you to create your own control sequences capable of meeting the most demanding control requirements.
