GrowControlTM GC-Pro Platform
GrowControlTM GC-Pro is a modular control system designed to be fully customizable to nearly any growing
control requirements. The core of the system is the GC-Pro controller itself where all of the settings are
stored and control operations take place. The GC-Pro obtains information about the environment from
climate sensors, hydroponics sensors, switch sensors and more. The controller uses this information and,
based on the settings you enter into the controls functions, turns equipment on or off via the controller’s
“outputs.” The controller and its outputs are low-voltage wet contacts (24Vdc) designed to be connected to
Agrowtek’s RX/CX relays to switch AC mains power to equipment. Outputs can also be wired to custom
contactor panels with 24Vdc pilot relays to switch equipment power.
Included 24Vdc power
supply operates controller,
sensors and relays.
~AC Mains Power
Auxiliary 24Vdc power supply
can be added if included
power supply is not sufficient
for all peripherals.

Overview
The GC-Pro cultivation controller is an advanced micro-processor based controller utilizing precision
electronic climate sensors to offer intricate control of your environment. GrowControlTM is equipped with a
broad array of flexible features, modes and options to suit nearly any climate controlled environment.
Settings can be entered easily on the controller screen or with the GrowControlTM PC software.
The GC-Pro is capable of monitoring and controlling up to two different environments (zones) from one
control unit.
Most controls settings have separate day and night set points which allow you to operate equipment
differently during these respective periods to obtain optimal crop response.
The PC software can be used to completely control and monitor the controller locally or from afar. Data can be
logged indefinitely to standard .csv files and live charting displays historical graphical data for up to two days.
Typical Applications
GrowControlTM controllers are designed for the discerning horticulturalist and can be tailored to any use from
hobby applications to mid and large-sized commercial environments.
GrowControlTM contains many features for use in both greenhouses with sun-light as well as indoor
environments that do not have the benefit of natural sun light.
Terminology
GrowControlTM takes information from its sensors and clock, and compares the readings with the settings
entered by the operator. The controller then decides whether to turn equipment (outputs) on or off.
Analog sensors are those that have a variable value such
as temperature, humidity, etc.
Digital Input sensors are those that act like a switch and
are either on or off such as a float switch.
Controls Functions are the functions built into the
controller such as timers, thermostats, humiditats, CO2
injection, nutrient dosing, etc.
Outputs are what equipment is connected to on the
controller such as lights, fans, pumps, etc.
Zones are separate environments that are independently monitored and controlled with sensors in each zone.
FlexnologyTM
Multiple controls functions can be assigned to a single output for maximum control flexibility.
For example: a ventilation fan can be controlled by a cooling thermostat and a de-humidify humidistat at the
same time. A timer could also be setup on the same fan output during the night, for example, to bring in fresh
air on a time schedule.

Inputs & Outputs (I/O)
Outputs
The controller turns equipment on and off by controlling outputs. Each control function (thermostats, timers, etc.) is
programmed to one of the available outputs as desired.
The controller comes with twelve (12) programmable outputs (GC-Pro-xD is equipped with 20 outputs.) The user names each
output for reference then assigns control functions to the outputs as required.
Note: “Output Sequence Delay Timer” may delay the activation of any output by the delay time. This prevents multiple
outputs from activating simultaneously thereby reducing electrical load spikes.
Inputs
Four (4) “Digital” inputs are available to connect switch type sensors (float switches, door switches, leak sensors, smoke
detectors, etc.) Digital inputs can be programmed to act in a variety of different ways including turning an output device on or
off when the input it tripped.
Touch Panel
The I/O controls menu displays the current status of all the digital inputs and outputs. An input or output will be green when
activated, and red when inactive. Touching any of the input or output numbers will display the settings for that input or
output.
Software
The PC software contains the I/O controls on the ‘IO’ tab. If an input or output is activated, it will be shown in green.
Click an input or output button to start, stop or set to automatic mode, change the name or set the interlock/interrupt
output#.
Status button indicates run or stopped,
and day or night (if in run mode.) Inputs and outputs that are on are
shown in green; off are shown in red.
Pressing an input or output number
displays the control functions for the
input or output.
Output can be named for reference,
manually operated or disabled, and be
programmed to disable another output
when on (advanced settings.)

Output Settings
Outputs are devices that the controller turn on or off as required (such as lights, fans, pumps, etc.) Each output has its
operation designated by the controls functions, (described later) but the output can be manually operated or disabled, and can
utilize an ‘interrupt’ function.
Output Interrupts
The interrupt function causes a selected output number to be disabled any time the parent output is activated. This function
is most typically used to prevent CO2 outputs from activating when ventilation stages are active.
Interrupt Example: If the output shown above (output #1) is assigned to ventilation fans, and output #2 is assigned to CO2,
enter “2” in the interrupt value of output 1. (Also see temperature limit functions to cancel CO2 in anticipation of ventilation or
to prevent combustion generators from operating above a set limit temperature.)
Input Settings
Digital Inputs are those that act like switches (float switches, leak sensors, motion sensors, smoke detectors, etc.)
Digital inputs can be assigned to perform specific tasks when activated such as activate or disable an output.

Controls Functions
“Controls” are functions such as thermostats, timers, etc. that the controller uses to operate the “outputs” (greenhouse
equipment.) The grower decides which of the controls functions the controller will use to control the equipment in the
environment(s.)
Any control function that is used must be assigned to an output or VSC channel #.
Any control function can be disabled by setting the output number (and VSC channel) to 0.
Multiple controls functions can be assigned to the same output.
For example; a cooling thermostat and a de-humidistat can both be assigned to an output connected to a ventilation fan in
order to turn the fan on for either high temperature or high humidity.
Controls functions can be assigned to a zone.
The controller can monitor up to two sensor zones and the control you set up needs to know if it should respond to the sensor
readings for zone 1 or zone 2. (A zone number of 0 defaults to zone 1.)
Touch Panel
The controls functions are accessed via the main menu.
Software
The controls functions are accessed on the “Controls” tab page when connected to a controller. Click on the controls buttons to
modify the settings.
Active controls are highlighted with their respective function color.
Clicking on a control button will display the settings for that control function.
Press “Menu” button to enter main
menu. Press “Controls” to enter controls menu.
Controls are broken down into basic
categories. Press “Next” to access
additional controls.

Lights, Day & Night Mode Controls
The day and night modes controls determine how the controller will decide when to switch between the day and night settings
that are entered in controls functions.
Day/Night Mode
“Synchronize with Lights” mode synchronizes with the lighting timer; day when lights are on, and night when off.
“Light Irradiance Sensor” mode activates day mode when the light level reaches the “W/m2 Day” set point and activates night
mode when the light level falls to the “W/m2 Night” set point. This mode is intended to be used in environments with sunlight.
“Flip-Box Mode” is designed to be used with dual zone environments. When in flip-mode the controller will assume zone 1 is in
day mode when the flip trigger is off and zone 2 is in night mode. When ‘flipped’ zone 1 will be in night mode and zone 2 will
be in day mode. Use the light flip timer to set the flip time, change delay and trigger outputs.
Day/Night Outputs: Enter an output number to activate during the day or night period. For example, if you want air
circulation fans to run all day but not at night, enter the fans output number into the “day” output.
W/m2 Day/Night: Light intensity levels which determine day and night when using the light sensor mode, and which will
activate light alarms (see alarms.)
The day and night modes are accessed via the “Controls” menu.
System administrator password is required to access the day/night mode menu if set.
The day and night mode settings are accessed on the first page
of the controls menu by pressing the “Light” controls button
then “Day/Night Mode” button.
Each zone can detect day/night from the lighting
timer, light sensor or flip box position. Also, an
output can be activated during the day or night
p
eriod.

Lights Timers
The controller has special timer controls for lighting equipment including two 24-hour lighting timers (one for each zone,) each
with their own secondary ‘B’ bank. The ‘B’ bank can be delayed to activate after the ‘A’ bank for reduced electrical load on
start-up.
Each lighting stage has its own hot-fire prevention timer which will prevent the lighting outputs from re-activating for a set
duration once turned off. The hot fire prevention timer ensures lamp bulbs and ballasts will not be damaged due to hot-firing.
See ‘System Settings’ for hot-fire timer configuration.
Lighting Timer: Enter the time of day (in 24-hour format 0:00-23:59) when the lights should turn on and off.
Output: Enter the output(s) for the primary (A) and secondary (B) lighting banks as connected to the controller. If B is not
used, leave it assigned to 0.
Delay (B Bank): Delay time (seconds) to start bank ‘B’ after bank ‘A.’
The lighting menu is accessed from the “Controls” menu under the “Lights” button.
Light-Flip Box Control
GrowControlTM is designed to safely and properly switch over lights on a light flip box. For extended light flip box contactor life,
ballasts should be turned off prior to switching the flip box trigger position. This prevents arcing and burning of the contacts
and also ensures the ballasts fire the bulbs properly after being switched.
Simply set the time of day to turn the flip trigger on and off and enter a delay time for switching. The delay time (seconds) will
be applied after turning off the lighting output before changing the state of the flip trigger, and after the trigger has been
flipped before re-starting the lights.

Temperature Controls
Temperature controls consist of heating and cooling thermostats, and high and low temperature limits (shut-offs.)
Heating & Cooling Thermostats
Cooling Thermostats turn an output on or open VSC’s when the temperature is too hot. Cooling thermostats are used to
operate ventilation fans, curtains, windows, chillers, evaporative coolers and more.
Heating Thermostats turn an output on or close VSC’s when the temperature is too cool. Use heating thermostats to
operate heating systems including hvac air handlers, water heaters, floor heating and more.
Limit Thermostats
Lo-Temp Limits turn an output off or close VSC’s when the temperature is too cool. Low temperature limits can be used to
close down vents and curtains or stop ventilation fan outputs from operating if the outdoor temperature is too low.
Hi-Temp Limits turn an output off or close VSC’s when the temperature is too hot. High temperature limits can turn off CO2
combustion generators, light banks, and other equipment if a room is too hot, or to disable heating systems if the outdoor
temperature is above a minimum.
Limit thermostats take precedence over other commands to an output # or VSC channel.
Staging Thermostats
Thermostats can be staged for multiple levels of heating and cooling.
In the example above:
Heat 1 will operate any time the temperature drops below 58 and will continue to heat until 60.
Heat 2 will operate any time the temperature drops below 50 and will continue to heat until 55.
Cool 1 will operate any time the temperature rises above 75 and will continue to cool until 72.
Cool 2 will operate any time the temperature rises above 85 and will continue to cool until 80.
Cool 3 will operate any time the temperature rises above 90 and will continue to cool until 85.
