All zone controllers support an occupancy sensor. The occupancy sensor switches the controller from occupied mode to standby mode. This occurs in normal occupied mode during a set time period, when local activity is absent. When in standby mode the zone controller uses standby temperature setpoints that are higher and lower than the occupied cooling and occupied heating temperature setpoints. These standby setpoints save energy by reducing the demand for heating and cooling in an unoccupied zone. The sensor also uses unoccupied flow setpoints for VAV zone dampers. You can enable the occupancy sensor in the Zone Setup screen of the System Manager or Zone Coordinator. You can set occupancy sensitivity and time delay until standby locally at the sensor.
