This is the simplest way to operate a CO2 generator. It basically incorporates the unique features of our CYCLESTAT-4P repeat cycle timer. This specialized timer has a built-in photosensor switchable to limit its operation to light hours only. During the photoperiod it will cycle the generator at your desired timing schedule.
TIMING AND VENTILATION CONTROL
The diagram below is similar except it has the added advantage of coordinating the ventilation with the CO2 enrichment. The CO2 generator is defeated during an exhaust function and immediately cycled to replenish the CO2 when the ventilation is complete.
CO2-STAT SET POINT CONTROLLER
This is like a thermostat for your CO2. Of course it is not a thermostat but it is as simple to use as that. Just set your desired CO2 level and there you have it. It's just that easy. The SPC-1 monitor uses infrared technology to turn CO2 equipment on and off based on a 20 ppm variable and not allow it to operate at night. In this diagram it is plugged into a CT-DH-3 atmospheric controller to coordinate with ventilation but you could just as well use it without the CT-DH-3 as a stand alone CO2 controller.
ULTIMATE CO2 MONITOR CONTROLLER SYSTEM
This diagram demonstrates the optimum equipment and control scenario to coordinate ventilation and CO2 enrichment. The CDMC-6 monitoring system includes a microprocessor controller CDDS-2 with "overshoot logic" and other enhanced features to maximize performance and improve CO2 economy. It comes with the CDM-6000 remote infrared CO2 sensor. CO2 is produced by the generator and metered precisely upon demand by the CDMC-6 Monitor Controller. CO2 is defeated during exhaust cycles by the CT-DH-3 atmospheric controller. CO2 is not produced during darkness hours.
