## Description

CO2 Controller Carbon Dioxide Controller Air Quality Monitor CO2 Meter with Day and Night Control Relay Function, NDIR Sensor Probe Cable, CO2 Detector for Plant, Grow Room, Green House, Garden, Home: desertcart.com: Industrial & Scientific

## Features

- Fully Customizable Zones: Tailor your environment to any species. Easily program specific Target and Zone values. Includes dedicated "Human" and "Plant" modes to switch between indoor air quality (IAQ) safety and high-output greenhouse production.

## Questions & Answers

**Q: Whats the maximum set point.will it maintain 1500ppm co2 levels?**
A: The controller can easily maintain a 1200sq ft room 10 ft ceiling at 3000ppm.  We just use a small 1/4 inch tube into the room and let the fans in the room blow it around.  It could easily go higher, but we do not want to waste the CO2

**Q: Will this turn on my burner automatically if the levels get to low?**
A: Hi, for your reference please check the information on pages 6-7 of the manual. If you have any specific questions regarding the contents of the manual you may contact our customer service representative through an Amazon message. They will handle your question and provide the best solution for you.
