5.1.4 Target Temperature
The Target Temperature is the temperature which 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 Natural Ventilation Curtain Machines
Under normal circumstances the natural ventilation curtain machines should be controlled
automatically (Manual/Auto switches set to “Auto”). When controlled automatically, if the
controller needs to open the curtains, the curtains will automatically open. If it is necessary to
manually open or close the curtains for any reason do the following:
Using The Manual Switches:
1. Find the switches for the machine you want to run and check that the Open/Off/Close switch
is in the off position. This makes sure that the machine does not run until required.
2. Place the Automatic/Manual switch for that machine in the “Manual” position.
3. To open the machine place the Open/Off/Close switch to the position marked “Open”.
4. To close the machine place the Open/Off/Close switch to the position marked “Close”.
5. Finally when you are finished positioning the machine, place the switch back into the “Off”
position. Note: "Off" position is between "Open" and "Close".
6. When you are ready for the controller to take over control of the curtain, place the
Automatic/Manual switch in the automatic position.
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 of the program items for the controller have a parameter
number assigned to them. The product label located on the front cover includes the Program Parameters
