the green LED’s beside the main display. Whichever LED is lit is the parameter you are
viewing. You can easily see “Outside Temperature”, “Var/Timer Percentage”, and “Target
Temperature”.
Room Temperature
The average of the sensors located inside the house.
Outside Temperature
The temperature read by the sensor located outside the house. (Sensor 3)
Var/Timer Percentage
This parameter is the percentage of the timer cycle that a stage on a timer will run.
Target Temperature
The temperature the system tries to maintain.
To adjust these settings, press the mode button until you see the setting you want to adjust.
Then use the + button to raise the value, and the - button to lower the value. When you are
finished setting a new value, either press the mode button again, or do nothing, and the
system will return to normal operation within a few seconds.
5.2 Running Curtain Machines
Under normal circumstances the machines should be controlled automatically. This way, if
the controller needs to open the curtains, it will open them. If, however, you want to open or
close them for any reason do the following.
1. Press the + and - button at the same time and hold them down for 5 seconds. When the
controller is in manual mode, the display will flash “PC”.
2. To open the machine press the + (Open) Button
3. To close the machine press the - (Close) Button
4. Finally when you are finished positioning the machine, press both the + and - buttons at
the same time, and hold them for 5 seconds.
5. The controller will take control of the curtains at this point.
6. Program Mode
Settings that are usually set up once per growout, or maybe even just for summer or winter are
referred to as program parameters and are accessed by taking the controller to program mode. Some
examples of these settings are Curtain Runtime, Stages on Timers, and Sensor Calibration.
To get to program mode, press and hold the “Mode” button for five seconds. When the controller has
entered program mode, the main display will flash between “P1” and the value of this parameter.
The “P1” is known as a parameter number. All the program items for the controller have a parameter
number assigned to them. The numbers are listed in the section called “Program Reference” in the
back of this manual with a short description of each parameter.
When in the program mode, you change the current parameter by using the + and - buttons as needed.
When you have finished with the current setting, press the “Mode” button to move to the next
parameter.
Look at the stage status indicators. If the light for stage 1 is lit, the parameter you are programming is
for stage 1. To go to stage 2, continue to press the mode button until the stage 2 indicator light is lit.
