TROUBLESHOOTING SymptomSolution No output Check wiring. Ensure power supply meets requirements. Temp or VOC reading error Verify control panel software is configured for correct output scaling. Verify accuracy of test instrument. Observe installation guidelines Verify unit is located away from sources of hot/ cold. Install insulation foam gasket provided to prevent thermal conduction from inside wall. COMPUTER ROOM OUTSIDE WALL OR WINDOW TOO HOT/COLD INSIDE WALL TOO HOT/COLD COPIER TOO NEAR EQUIPMENT OR DOORWAY GOOD LOCATION GOOD LOCATION GOOD LOCATION 3. If installing in a junction box, check that provided insulation covers entire junction box opening to ensure reading accuracy. 4. Snap on screw covers to complete installation.

Locate sensor in an area away from ventilation sources and heat generating equipment and appliances. Sensor should be mounted at light switch height in a vertical orientation. NOTE: Do not install sensor in multi-gang electrical boxes with line voltage or other electrical devices. 2.

Revised 09/30/2020 Document #152-0402-0A VOC SOURCES VOC means volatile organic compounds which can be found in a number of harmful and other gases, odors, and smoke. This product senses ethanol which is a product of many contaminants, some of which are listed below for reference. VOC ContaminantSources Harmful Gases Paints, glues, solvents, furniture, mattresses, carpet, flooring, building products Other gases Alcohol, cleaners, perfume, cooking smells Odors Rotten food, flatulence, breath, cosmetics, pet pee SmokeCigarette smoke VOC READINGS The output of this product has been converted from a raw Ethanol concentration into an intensity value, ranging from 0-500. An environment with normal air quality will typically read about 100 on this scale (7.2mA when using 4-20mA scale, 2V on a 0-10V scale, or 1V on a 0-5V scale). Suggested control actions are listed below. Upon initialization, the sensor will quickly adapt to the installation environment. However, for the first 1.5 hours of initialization, only large changes will be transmitted. After the first 1.5 hours, smaller changes will also be recognized. If initialization is done in polluted air, initialization may take longer. This sensor does not detect absolute VOC, only changes in its intensity based on a 24 hour cycle. If multiple sensors have different histories, it may take 1 to 12 hours for their readings to converge.
