The CHHC-4 controls every environmental condition. Cooling, Heating, Humidification and CO2 are all coordinated into one easy-to-use and reliable controller. Separate Day and Night settings. Select Fuzzy-logic mode or change to Generator mode when using a CO2 generator.
The CHHC-4 combines an accurate digital temperature and humidity sensor with a state of the art NDIR CO2 sensor in one reliable and easy to use controller. By controlling supplemental CO2 with PPM (part-per-million) accuracy, plant growth can be accelerated by as much as 30%.
Increasing the CO2 from normal atmospheric level of 375 PPM to between 1250 PPM by using either compressed CO2
or operating a combustible gas CO2 generator has never been easier. The CHHC-1 measures the carbon dioxide level and
automatically turns ON and OFF the CO2 device to accurately keep the CO2 level at the desired level.
The combination remote sensor assembly is also a great feature that allows the user to place the sensor up to 16 ft from
the controller. The combo-probe contains a highly accurate temperature, humidity, light and CO2 sensor. The sensors are
enclosed in a shielded body and use high-quality shielded wiring to resist electronic noise from electronic ballasts or
other EMI / EFI noise sources.
