Installation
• Mount the Controller on the wall. Place the remote sensor at plant
height in an area with good air circulation. Avoid placing the sensor in
a location with direct, intense exposure to light.
• Connect the sensor cable to the bottom of the unit using the
quick-disconnect screw.
• Plug the Controller into a 120V NEMA 5-15 wall outlet.
• Turn the power on and allow the unit to warm up for 5 minutes.
While the unit is warming up, the display will read “CO
2
heat.”
• Program the desired settings before connecting any devices.
• Plug the devices to be controlled by the unit into the
receptacles on the unit’s sides.
• Ensure the devices being connected to the
Controller have the proper voltage and will
not exceed the maximum amperage rating
of the unit.
• Before using a sulfur vaporizer around the
Controller, remove the remote sensor
from the affected area or turn the unit off
and cover the sensor with a protective
plastic bag. Remove the bag before turning
the Controller back on. Note: Failure to
protect the remote sensor during sulfur use
will result in damage to the infrared CO
2
sensor and void the warranty.
• Do not expose the unit to water.

Error LEDs
When the Controller is functioning normally, the ambient CO
2
level,
temperature and humidity will change slowly but steadily. If the
Controller does not detect a change in CO
2
level, temperature or
humidity within a 1-hour period, the unit will deactivate the affected
output and the corresponding green error LED will flash to indicate
which device may be malfunctioning. Ensure the device and remote
sensor are functioning properly. To reset the error, press the
“Enter/Reset” button.
Adjusting Photocell Sensitivity
• To change the photocell’s sensitivity, hold the DOWN arrow
button for 3 seconds. The current setting will be displayed.
• Press the UP arrow button to increase the number displayed,
decreasing the amount of light required to activate the photocell.
• Press the DOWN arrow button to decrease the number displayed,
increasing the amount of light required to activate the photocell.
• Press “Enter/Reset” to accept the new setting.
Selecting Temperature Settings
Temperature Display:
Hold the UP and DOWN arrow
buttons for 3 seconds to change the temperature display from
Fahrenheit to Celsius.
Temperature Day:

“Deadband” button under “Temp.” The display will read “d.CooL__F.”
Use the UP and DOWN arrow buttons to adjust the setting. Press
“Enter/Reset” to accept the new setting. To set the heating dead-
band, press the “Deadband” button twice under “Temp.” The display
will read “d.HEAt__F.” Use the UP and DOWN arrow buttons to
adjust the setting. Press “Enter/Reset” to accept the new setting.
Note:
To prevent the unit from activating both the cooling and
heating devices at the same time, the difference between the heating
and cooling set-points must be greater than the combined deadband
set-points.
Selecting Humidity Settings
