Welcome Hired Hand has taken every effort to launch the agricultural industry into the 21st century. Our latest effort is the System 1000 Power Vent Eight Stage Controller. This versatile controller offers many of the features found in much more expensive controllers, while maintaining its entry level price. These features include: ë 8 stages of heat and cooling--plus one variable speed fan stage. ë Automatic daily temperature reduction (ramping). ë Automatic Pressure ramping.
Controller Basics The front of the controller is known as the facepad. This is where all operational commands are given, and current condition information is received. There are ten pressure sensitive "buttons" on the facepad. These "buttons" are the red colored arrows and rounded squares. To operate the controller, press the square, or arrow desired. The functions of the ten buttons are as follows: Auto On -- Shifts the controller into automatic mode.
Why Constant Pressure? By maintaining the pressure in your house at a constant slight vacuum you can be sure that fresh air enters the enclosure at a steady rate from all inlet areas. Also, with a more even air entry, a better mixing of outside air with inside air will occur, giving a more uniform temperature within the enclosure. The key ingredient for proper mixing of air is the speed in which the air enters the house. If cold air is drawn in too slowly, the air will drop to the floor, causing drafts.
High volume of warm, slow moving air lower volume of higher velocity cold air enters the building and mixes with the warm air in the ceiling of the building. The cold air is then slowed, and warmed before reaching ground level The above illustrations show that you need a different rate of air flow when the temperature changes. This is accomplished with the ramping feature.
Features Every grower has different needs; thus the Controller has many features that can be omitted or included at will to align the system to your individual needs. This section will cover the various features, including a brief description, and in most cases give an example to show the flexibility and ease of setup of this controller. Ramping Temperature Ramping Ramping is a special feature that allows for gradual temperature reduction during a growout.
If outside temperature is warm, it will allow you to take in a large volume of slow moving warm air, but when outside air is cold, the unit will adjust to allow only a low volume of fast moving cold air. 100 90 80 70 Temp (F) 60 50 40 30 20 10 0 Negative Pressure ("w.c.) The preceding graph shows what the ramp mode looks like on paper. The vertical lines show in-house pressure, whereas the horizontal lines show outside temperature.
Maximum Speed -- Usually set at 100% to gain maximum cooling capability Maximum offset -- The distance in degrees above or below target temp when the fan will reach maximum speed Minimum Speed -- The minimum speed the fans on the Variable speed circuit will run. Minimum Offset -- The distance in degrees below target temp when the variable speed circuit will engage the fan(s). Var. Speed Sensors -- Use the change setting up and down arrow keys to chose the sensors to control the variable speed circuit.
until you see the time you want the lights to turn on. Press the Select Features up arrow key and "Cycle #1 -- End Time" (The time for lights to be turned off) will be displayed. Enter the time as before, then press the Select Feature up arrow. This process will continue for each light cycle you selected.
NOTE: In older versions of this controller, the variable speed fan stage would shutoff whenever the controller was in tunnel mode. However, in version 0.07 and later you may select whether the variable speed fan stages continues to run or shuts off. Timer The system has a built in timer which can be used with any cooling stage. This timer can be adjusted in many ways. The timer period can be set from one to twenty minutes.
using the Change Setting arrow keys. Repeat for each of the four sensors as needed. Manually Set Speed This option allows you to experiment with the variable speed fans. If you are not sure of the speed you want, you can test here until you find the right setting. The controller will ask for a percentage, then when entered, will run the fan, or fans at that percentage and ask if you would like to change again. This feature is only operable when in selected features.
This means that Sensor 1 has been keeping records for 14.37 hours and during that time, the temperature at Sensor 1 has dropped to a low of 4.0 degrees below Target Temp and has reached a high of 1.0 degrees above Target Temp. Example of Sensor 1's 2nd Display: -S1 Avg. from target -0.4 f 14.37 hours This means that Sensor 1 has averaged 0.4 degrees below Target Temp during the past 14.37 hours. Example of Stage 1 Display: Stage 4 Runtime 10 hours and 2 min.
Alarms High Pressure Alarm The High Pressure Alarm will send a signal to your existing alarm system when pressure exceeds the High Pressure Setpoint. (High Negative Pressure.) This alarm warns if the vents did not open for some reason. Low Pressure Alarm The Low Pressure alarm will send a signal in the same manner as the High Pressure alarm, but only if pressure drops below the low pressure setpoint. This alarm warns if the vents failed to close for some reason.
Offset and Differential Offset: The point above (cool) or below (heat) target temperature where the stage turns off. Differential: The difference in degrees between the temperature a stage comes on and the temperature the stage goes off. Examples Heat Mode: If the Target Temp is set at 80 degrees, Offset set at 4 degrees, and Differential set at 2 degrees, The System will engage Heat Mode when building temperature reaches 74 degrees and the curtains are closed.
If the Target Temp is set at 80 degrees, Offset at 4 degrees and Differential set at 2 degrees, The System will disengage Heat Mode when building temperature reaches 76 degrees. Example: Target Temp - Offset = Heat Mode Off 80 - 4 = 76 Cool Mode: If the Target Temp is set at 80 degrees, Offset set at 5 degrees, and Differential set at 2 degrees, The System will engage the fans when building temperature reaches 87 degrees.
Programming Stages Use the Select Feature up arrow key to select "Program Stages". When the menu is displayed, use the Change Setting up arrow key to select yes, you want to program Stage 1. Your first task will be selecting the mode (heating or cooling) for the stage. Below is a list of several different modes. Your choice will depend on how you desire to program your building. Example First: Select desired mode by pressing the Change Setting up or down arrow keys. Below are several modes to choose from.
Third: Select the Offset in Stage 1. This is the amount in degrees from your target temperature where a stage will turn off. Use the Change Setting up and down arrow keys to select the Offset you wish. If the stage is a Heat Mode, subtract the number you have selected for an Offset from your target temperature. This will be where the stage (Heat Mode) will disengage. If this stage is a Cool Mode, add the number you have selected for an Offset to the target temperature.
Operation With Levels Save Level The System can save up to four programs. This feature lets you program for different periods in a growout when different environmental conditions may be needed. Push the Select Feature up arrow key until "Save Level" is displayed in the window. Use the Change Setting up arrow key to select "yes", next, push the Select Feature up arrow key. Level Menu, and Level Number will be displayed. Use the Change Setting arrow key to select the level number you would like to save.
Keypad Security Locking the Keypad The keypad on the System 1000 Power Curtain Controller may be locked to prevent accidental tampering with the intended program. To lock the keypad, press and hold the Change Setting up and down buttons simultaneously. The word "locking" will appear in the lower line of the controllers display. Keep holding the buttons until that word changes to the word "locked", then release. This should take from five to ten seconds.
Initializing the Controller Initializing the controller means returning the controllers programming to the original factory settings. If you are having trouble with the controller and think it might be in the programming, you can re initialize the controller by following this procedure. Program Features Select Feature Change Setting 1. Cut power to the unit. 2. Re-apply power to the unit. 3. While the controller is starting up, the controller will darken all segments of the screen.
Variable Speed Wiring Fan Motor 120 VAC or 240 VAC Hot Breaker Panel Terminals on controller labeled In Out When wiring the Variable speed fans, connect the "hot line" from the breaker panel to the terminal positions marked "Variable Speed In" on the board in the bottom of the controller. From the Out connection, run a wire to the fan motor. For operation with the Remote Fan Drive Unit, you will need to wire the system as shown below.
