5. Basic Overview
The Farm Hand Power Vent has been designed with the producer in mind. Routine tasks such as changing
the pressure limits are easily reset, and are familiar in nature.
This controller has only two basic settings Target High Pressure, and a Target Low Pressure. Think of these
settings as the two needles on a photohelic. The controller will open and close the vents as needed to
maintain pressure between these limits.
Low Pressure
High Pressure Limit
Low Pressure Limit
When pressure is
in this range, the
controller will not
adjust vents.
When pressure is
above the high
limit, the vent
machine will open
vents to lower
pressure.
When pressure is
below the low
limit, the vent
machine will close
vents to raise
pressure.
High Pressure
Room Pressure
Now that we know how the controller works, lets move on to how to set up those limits.
Press the mode button a few times, and you will see that the display changes each time. If you will look just
to the right of the display, you will see four green lights labeled Room Pressure, Target High Pressure,
Target Low Pressure, and Outside Temperature. The green light tells you what setting you are looking at in
the main display. If the light beside Room Pressure is lit, the numbers in the display show you the pressure
in your building.
