Demand-Controlled Ventilation (DCV) - SVACH

DCV sensors most commonly measure carbon dioxide (CO2) and/or relative humidity. Typically, the ventilation system withdraws air from “damp or humid” rooms (bathrooms, kitchens, laundry, work areas) and supplies air to “dry” rooms (offices, living rooms, bedrooms). Occupancy sensors, like those used for lighting systems, may also control ventilation systems. Occupancy sensors are a ...
