LC-VEC100-0 Johnson Controls Verasys

The VEC100 controls either VAV or changeover bypass (COBP) units. You can use this single controller to control units that are not a Smart Equipment units. The VEC100 ships with an application that supports up to two stages of heating and four stages of cooling. Additional applications are available to control modulated heating, modulated cooling, and a heat pump. You can configure all of the controller applications for use in a VAV or COBP system and to control an economizer. The controller automatically uses analog sensors when you connect them. If you connect a return air sensor to the controller and the system is a VAV system, the warm-up feature is integrated for control. If a CO2 sensor is connected and an economizer is installed, demand ventilation control sequences are available. For more information about the sequences that this controller uses, refer to the application note of the relevant application and the Verasys System Operation Overview Technical Bulletin (LIT-12012370).
