The constant volume application is a Verasys application designed to control equipment that serves a single zone. You can load the application into the VAC1000 or VAC3000 depending on the equipment that you want to control. The constant volume application adds to the features present in Smart Equipment and extends the capabilities of the TEC3xxx series for third-party equipment.
The application includes support for up to four stages of cooling and four stages of heating, modulated 0 V to 10 V output for heating and cooling, and heat pump with an additional two stages of supplemental heat available. The constant volume application can control a mixed air damper or set a minimum outside air damper position, and meet Title 24 compliance for the state of California.
Other supported features include occupancy scheduling, outdoor air lockouts, dehumidification, humidification, demand control ventilation, and much more. Refer to Verasys Constant Volume Controller Application Note (LIT-12013067) for more information.
