162. ventilation rate means the equipment can condition air at a maximum ventilation rate that is greater than the required ventilation rate for maximum occupancy A proportional anticipatory strategy will cause the fresh air supplied to increase as the room CO level increases even though the setpoint has not been reached By the time the CO level reaches the setpoint the damper will be at maximum ventilation and should maintain the setpoint In order to have the CO sensor control the economizer damper in this manner first determine the damper voltage output for minimum or base ventilation Base ventilation is the ventilation required to remove contaminants during unoccupied periods The following equation may be used to determine the percent of outside air entering the building for a given damper position For best results there should be at least a 10 degree difference in outside and return air temperatures OA RA occ e etu To Outdoor Air Temperature OA Percent of Outdoor Air Tg Return Air Temperature RA Percent of Return Air TM Mixed Air Temperature Once base ventilation has been determined set the minimum damper position potentiometer to the correct position 56 The same eguation can be used to determine the occupied or maximum ventilation rate to the building For example an output of 3 6 volts to the actuator provides a base ventilation rate of 5 and an output of 6 7 volts provides the maximum ventil
