1. Product Overview
Model: RAD-0502 CO2 Controller for Grow Rooms
Thank you for selecting the RAD-0502 CO2 Controller for Grow Rooms, which is designed to
regulate CO2 levels and allows growers to set high/low targets to maximize plant yields
and profitability.
The CO2 Controller for Grow Rooms uses a dual beam NDIR technology to accurately
measure CO2 concentrations up to 3,000ppm. With a built-in temperature measurement
and photo sensor, the controller can turn off relays during dark periods to save Carbon
Dioxide (during green house mode). Furthermore, the CO2 grow controller is an ideal solution
for many growers who utilize the device across indoor greenhouses, cultivation centers,
hydroponic rooms, or anywhere regulated CO2 levels are important for plant growth.
• Accurate CO2 control for small to large sized indoor grow facilities
• Control 2 zones with 2 sensors
• Customizable CO2 set points for high and low target levels
• Dual beam NDIR technology accurately measures CO2 concentrations 0-3,000ppm
• Built-in temperature, humidity, and light
• Relay output can automatically control CO2 generator or compressed CO2 tanks
• Versatile modes for greenhouse or HVAC

The Range Setting of Temperature and Humidity This RAD-0502 CO2 Grow Controller can determine a required temperature and humidity range by setting the upper and lower limits of temperature and humidity. This device can also record the effective light time by setting the value point of light intensity and avoiding frequent turnoff of the relays by setting a buffer of light intensity.
- Page 11 19. Temperature and Humidity Calibration The RAD-0502 CO2 Grow Controller can also calibrate the temperature and humidity for the device. The following display example below illustrates temperature calibration. 1. Press and hold the mode key for 3 seconds to enter into the setting mode 2.

Light Hysteresis Setting In greenhouse mode when the light intensity decreases, it is lower than the light set point minus the light hysteresis. This means the CO2 relay will always be turned off. When the light intensity increases higher than the light set point, the CO2 relay will determine whether to open or close according to the current CO2 concentration.
