Comes with:

• New quick-disconnect on remote combo sensor for temperature, humidity, CO2 and light level. The combination sensor can be placed 16 feet from unit.
• 9-pin RS-232 connection for optional monitoring software.
• There are 3 environmental conditions which must be controlled for productive indoor growing. The CHHC-1 makes it easy to accurately control your "atmosphere" inside the area.
• Temperature: The CHHC-1 has 2 separate outputs to control cooling and heating.
• Humidity: The CHHC-1 can either increase or decrease the amount of humidity inside the area.
• CO2 PPM: The CHHC-1 controls carbon dioxide with Part-Per-Million accuracy
• The user can set separate day and night settings for temperature and humidity. The CO2 is activiated only during the "day" and has several modes of operation.
• Besides controlling your growing area, the on-board memory stores the highest and lowest measurements to verify proper conditions are maintained.
• No complicated menus to negotiate... the simple pushbuttons and LED display makes it EASY! The CHHC-1 uses a simple "operator interface" to access the settings and to recall the minimum and maximum recorded readings for CO2 level, temperature and humidity.

Benefits:

• Fuzzy logic mode can be used with compressed CO2 for greater accuracy.
• Simple auto-calibration of the CO2 sensor can be done in 5 minutes.
• Bright LED display shows the Temperature, Humidity and CO2 levels.
• Individual pushbuttons are simple to understand and easy to use.
• Cooling devices such as ventilation fans or air-conditioners connect to the cooling device receptacle.
• Heaters for coller climates can be connected to Temperature Receptacles.
• All functions can be controlled individually. You set both high and low temperatures for the Day and Night... the CHHC-1 figures out the rest.
• Controlled with Part-Per-Million accuracy.
• A separate humidifier or dehumidifier can have separate Day and Night settings and is connected to the humidity device receptacle.

How to use:

• Connect your CO2 generator or compressed CO2 solenoid / regulator assembly to the CO2 receptacle
