The VAV package consists of 2 parts, namely the thermostat and the EVC which is a combination of an actuator and a controller. The EVC’s are available in the stand-alone version (EVC) or in a BTL listed BACnet application specific version (EVCB).They are designed to control pressure independent single duct VAV or fan powered VAV with or without terminal reheat. The controller incorporates flow sensor, electronics and firmware of the VAV package. The EVC mounts directly to the damper jackshaft on the side of th VAV box. The attractive thermostat has a large LCD display with four push buttons for set point, occupancy override and programming.
