“CONTROLS”
OVERVIEW
“The CGC-1e controls your light cycles, temperature, humidity and CO2 levels… automatically! No more
guesswork! The CGC-1e lets you work smarter not harder.
24 HOUR, TIMECLOCK
The timeclock selected to run the CGC-1e performs all of the day to night transitions required for crops requiring controlled
photoperiods. It can directly control up to 1000 watts of HID lights.
To set the current time on the timeclock, turn the dial clockwise until the current time on the outer dial lines up with the arrow
on the inner dial. To set the timeclock on and off times, carefully push in each of the white trip levers at the times you want the
lights to be on.
*NOTE: If power is interrupted, the timeclock will have to be reset.
TEMPERATURE CONTROLLER
The CGC-1e utilizes a remote-bulb thermostat with a 36” lead to control ventilation and cooling functions. This allows you
to place the temperature sensor up to 36” away from the CGC-1e. The thermostat can be set to control temperature from
50 – 115’F.
The thermostat is coordinated with the CO
2
control system and the exhaust receptacles to maintain a constant temperature.
When the temperature rises above the set point selected on the thermostat, the CO
2
system is disabled and the Exhaust
receptacles are enabled. When the temperature level drops below the set point, the CO
2
system is re-activated.
IMPORTANT: To achieve the greatest accuracy, provide the CGC-1e with plenty of “fresh air”. The enclosure is designed to
allow air to pass over the humidity sensor.
HUMIDITY CONTROLLER
The CGC-1e utilizes a de-humistat to control ventilation and humidity levels. The de-humistat can control humidity levels
from 20% - 80%.
The de-humistat is coordinated with the CO
2
control system and the exhaust receptacles to maintain a constant humidity.
When the humidity rises above the set point selected on the de-humistat, the CO
2
system is disabled and the Exhaust
receptacles are enabled. When the humidity level drops below the set point, the CO
2
system is re-activated.
HYDRO MODE SELECT SWITCH
The Hydro mode select switch is used to select whether the hydro outlet will cycle 24-hours or only during the day. The mode
selector switch also doubles as a Hydro bypass switch. Each time the switch position is changed to the center “OFF” position,
the hydro timers will reset and initiate a new cycle. This comes in handy during set-up of the hydro pumps and timer settings.
NOTE: *Leaving the mode select switch in the center position disables the hydro function.
NIGHT ONLY DEVICE
An additional outlet is provided which is powered only at “night” when the lights are turned OFF. This works great for
heaters, fans and dehumidifiers, which need to run only at night.
PPM CO2 OPTION
The CGC-1e has a standard timed CO
2
control sequence, which can be improved upon greatly by simply connecting the
optional PPM-1c. Simple operation, user selectable set point and on-board calibration makes the PPM-1c the perfect
companion to the CGC-1e.
