The Titan Controls® Ares® Garden Heater is unique because it not only allows a grower to heat their garden but it also allows for them to manage and control the byproduct of the combustion process, CO2. This product can effectively detect both oxygen and carbon dioxide, and control the concentration of carbon dioxide when used in an unvented area. When the oxygen concentration in the atmosphere is reduced to 18.0% or less, the built-in Atlas® CO2 Controller with Oxygen Shutoff-Hardwire Controller automatically shuts off the Garden Heater. When the oxygen concentration returns to 19.0%, the Atlas® CO2 Controller with Oxygen Shutoff-Hardwire...
