The VAV/CAV 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/CAV or fan powered VAV with or without terminal reheat.

The controller incorporates flow sensor, electronics and firmware of the VAV/CAV package. The EVC mounts directly to the damper jackshaft on the side of the VAV box.

The attractive thermostat has a large LCD display with four push buttons for set point, occupancy override and programming
