This product controls temperature and CO2 in you grow area at your preferred day and nighttime settings. The built in ten (10) minute "CO2 delay" feature deactivates the CO2 equipment if the daytime temperature setting is exceeded by using a digitally based control system. The software polls the temperature setting ten (10) minutes after the CO2 outlet is defeated to verify that the temperature is too high, and then activates your exhaust fan or A/C to lower the conditions under the setting. If the temperature drops below the set point during the ten (10) minute "CO2 delay", then the exhaust process is defeated and the "CO2 ON" outlet is reactivated, saving your valuable CO2 and keeping it amongst the plants where it belongs.
