Sentinel CHHC-4i Digital Intelligent Total Environmental Controller

The Sentinel CHHC-4i is the most advanced CO2 controller available on the market today. It incorporates the proprietary S.I.C.E. – Sentinel Intelligent CO2 Enrichment – communication and control components and programming that are unique to Sentinel. This patent pending system allows for communications between Sentinel S.I.C.E series products, providing a level of control never before seen in your greenhouse, garden or grow room. The system works by a Sentinel S.I.C.E. series controller, such as the Sentinel CHHC-4i, measuring and monitoring your growing environment. As the atmospheric CO2 levels change, the controller will tell the Sentinel ICG series generator to increase output, decrease output, or go into idle mode...all computer controlled. In this way, a growing environment that has very low Co2 levels, such as the start of the day or after a ventilation cycle, can be rapidly brought back up to optimal growing conditions. As the optimal conditions are reached, the S.I.C.E. system can decrease Co2 output, making sure that the user defined optimal level is not overshot. As needed, the growing environment can be topped off with CO2 enrichment on a lower output setting, allowing for air conditioners and dehumidifiers to better deal with the heat and moisture loads associated with Co2 enrichment and maintaining more constant temperature and rH levels. New quick-disconnect on remote combo sensor for temperature, humidity, CO2 and light level. The combination sensor can be placed 16 feet from unit. There are 3 environmental conditions which must be controlled for productive indoor growing. The CHHC-4 makes it easy to accurately control your atmosphere inside the area. Temperature: The CHHC-4 has 2 separate outputs to control cooling and heating. Humidity: The CHHC-4 can either increase or decrease the amount of humidity inside the area. CO2 PPM: The CHHC-4 controls carbon dioxide with Part-Per-Million accuracy The user can set separate day and night settings
