“CONTROLS”
OVERVIEW
“The XGC-1 controls your lights, hydroponic pumps, exhaust fan or A/C, de-humidifier, heater and CO
2
level with
“Part-Per-Million” accuracy… automatically! No more guesswork!
24 HOUR TIMECLOCK
The timeclock selected to run the XGC 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 orange 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 XGC utilizes a remote-bulb thermostat with a 30” lead to control ventilation and cooling functions. This allows you to
place the temperature sensor up to 30” away from the XGC. 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 XGC with plenty of “fresh air”. The enclosure is designed to
allow air to pass over the humidity sensor.
HUMIDITY CONTROLLER
The XGC 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, dehumidifiers or any other device that needs to run only at night.
WHAT IS “FUZZY LOGIC”
 CO
2
Control?
What set’s the XGC-1 apart from the competition? Fuzzy logic… What is "fuzzy logic"? Fuzzy Logic can be compared to a
good driver. As a good driver approaches a red light, he or she applies the brakes to gradually slow down BEFORE getting to
the intersection. Fuzzy Logic uses the same idea to bring the CO
2
level up to the desired setting without going over the set
point. With Fuzzy Logic, relatively safe compressed CO
2
can replace LP / gas CO
2
generators economically.
The XGC combines an extremely accurate infrared CO
2
sensor with a state-of –the-art Fuzzy Logic module to give you the
most precise method of controlling supplemental CO
2
. SIMPLY SET IT… AND FORGET IT!
