The Verasys Constant Volume Controller is an application-specific controller for single-zone constant volume systems. Verasys can connect directly to any Smart Equipment controllers that are mounted to equipment. If there are no Smart Equipment controllers mounted, and the equipment has a conventional thermostat interface, you can use application controllers or a TEC3000 thermostat to connect them to Verasys.
The TEC3000 can also be used for constant volume or single zone systems. However, the constant volume controller has more inputs and outputs than the TEC3000. Table 1 compares the capabilities of the TEC3000, the constant volume controllers and Smart Equipment controllers.
