Hired-Hand Farm Hand Series: Vent Master 16 Stage - Manual (Page 5)

Part No. 4801-5098 Farm Hand Vent Master 2
(2) Farm Hand Vent Master with Variable Speed
The only difference between the models is the variable speed option.
The Farm Hand Vent Master Stage Controller is designed to be one of the simplest controllers on the
market to operate, but to also be one of the most powerful. The Vent Master combines the features of the
Farm Hand Stage Master 12 with the capabilities of the Farm Hand Power Vent into a single controller.
The Vent Master has four main regions on the faceplate: the main display, stage displays, the control
button region and the vent machine control region. The main display area includes the main display, and
four green LED’s which tell what the main display is indicating. If the green light beside “Temperature”
is lit, then the display is showing the display option chosen in the Program Mode under the parameter
PSd. Refer to Section 6.1 for an explanation of the PSd parameter.
On the left hand side of the controller face are the stage displays. When the controller is operating the
OnPoint of each stage (the temperature the stage will turn on) is displayed. Next to the stage indicators, is
a button with the number of the stage printed on it. Press this button to set the On and OffPoints for that
stage. (Stage OnPoints and OffPoints are discussed later in the manual.) The blank white region is for
labeling equipment such as (front heat, back heat, sidewall fans, etc.). Finally, there is a small red LED on
the bottom right of this white region. This is the stage status indicator. This light will be lit if the stage is
on, and will flash on and off if it is running because it is on a timer.
Just below the main display on the right hand side of the controller is the control button region. This
region has three buttons, Mode, +, and -. You will learn the use of these three buttons later in this
manual.
Finally, on the bottom right hand side of the controller is the vent machine control region. This region
includes an Automatic/Manual switch, and an Open/Off/Close switch for each machine.
5. Static Pressure Overview
The Farm Hand Vent Master has been designed with the producer in mind. Routine tasks such as
changing the pressure limits are easily reset, and are familiar in nature.
