Hired-Hand Farm Hand Series: Vent Master 16 Stage - Manual (Page 12)

Part No. 4801-5098 Farm Hand Vent Master 9
Note: In this manual, a stage's OnPoint parameter is referenced as (ON). A stage's OffPoint
parameter is referenced as (OFF). For Variable stages, the Minimum OnPoint is the value of
the (OFF) parameter. The Maximum OnPoint is the value of the (ON) parameter.
9. 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 Vent Machine Time Delay, 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 “PSd” and the value of this parameter.
The “PSd” 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 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.
9.1 Sensors For Display (PSd)
The user is given the choice as to what he/she wants to display for Room Temp. The choice is
made in Program Mode under the parameter PSd. The following is a list of choices:
PSd = Room Temperature Display
100 = Sensor 1
020 = Sensor 2
120 = Average of Sensors 1 & 2
003 = Sensor 3
103 = Average of Sensors 1 & 3
023 = Average of Sensors 2 & 3
123 = Average of Sensors 1, 2, & 3
9.2 Stage Parameters
The following parameters are used to program each stage on the Farm Hand Vent Master.
Through these parameters, the user has complete control over the operation of each stage. The
following sections explain each parameter in detail.
P1 = Stage Sensors
P2 = Stage Mode
P3 = Stage Timer Settings
P10 = Minimum Runtime Percentage (Variable Speed Stages Only)
P11 = Motor Curve (Variable Speed Stages Only)
9.2.1 Stage Sensors (P1)
A stage can be programmed to run off of any sensor or combination of sensors. The following is
the list of P1 options:
P1 = Stage Sensors
100 = Sensor 1
020 = Sensor 2
120 = Average of Sensors 1 & 2
003 = Sensor 3
103 = Average of Sensors 1 & 3
023 = Average of Sensors 2 & 3
123 = Average of Sensors 1, 2, & 3
