Features:
- VOC Alone or Temperature and Humidity Combination
- Achieves True Indoor Air Quality, Not Just CO2 Dilution
- Output is Correlated to a CO2 Value Allowing You to Ventilate Using ASHRAE's CO2-Based VRP Algorithm
Humans respirate Volatile Compounds (VOCs) as well as CO2. The BAPI sensor is able to measure these VOCs and indicate when a space is occupied just as well as a CO2 sensor. The advantage of the VOC sensor is that it measures air contaminants from other sources besides respiration, such as building materials, cleaners, perfumes and furniture and carpet off-gassing. So using this sensor for Demand Controlled Ventilation is a way of achieving true indoor air quality, rather than CO2 dilution. A further benefit is that it requires no additional work on your part. That's because the sensor converts the VOC reading to a CO2 equivalent level. This lets you use ASHRAE's CO2- based VRP schedule to ventilate. The unit is VOC alone or with temp and humidity sensing, temp setpoint and override. The optional display alternates between the measured values. The VOC level is indicated as"Good, Fair or Poor" by LEDs on the front of the unit.
