We give this fan a five star rating |
- Key Benefits:
- The self-calibration feature allows the user to calibrate the controller.
- 2 separate outputs can control heating and cooling.
- You can adjust the amount of humidity in the grow area.
- Efficiently controls carbon dioxide with parts per million accuracy.
- Remote temperature humidity, CO2 and light level sensor can be positioned inside the grow area. Complete with a 15 ft. cable.
- A C02 regulator is needed and can be found on our site. We recommend using the Sentinel brand.
For the money no beats this controller! We believe the Sentinel CHHC-1 is one of the best overall controllers on the market and provides our clients with a great value. The unit effectively controls Co2 (need to purchase the regulator sold separately), humidity, cooling and heating with separate day and night settings. You can choose fuzzy logic mode or switch to generator for co2 generators. The sensor can be placed up to 6 feet away from the controller. The unit operates up to 15 amps at 120 volts. Nicely digital! A great purchase!
