Hired-Hand Farm Hand Series: Vent Master 24 - Manual (Page 16)

Part No. 4801-5124 rev 10-03 Farm Hand Vent Master 24 14
SWX 3 - 5/10 minute timer
This switch selects between a 5 and 10 minute system timer. If the switch
is ON, the timer is 10 minutes.
SWX 4 - Sensor 3 Active
This switch turns off sensor 3. If the switch is off, sensor 3 is turned off.
Note: This is used to disable the sensor in the back half of a half house
brooding situation. This way the low temperature reading does not affect
the temperature readings for the rest of the house. Just be sure that Sensor
3 is placed in the non-brood end of the house. If the switch is ON, sensor 3
is used.
SWX 5 – Split Vent Units
If SWX 5 is ON, PowerTrak #1 will control the Vents and PowerTrak #2
will control the Tunnel mode. If SWX 5 is OFF, PowerTrak #1 and
PowerTrak #2 will always work together to maintain static pressure.
SWX 6 - Pascals/mm H
2
O
If SWX 2 is set for Metric units, and SWX 6 is set to ON, pressure is
displayed in millimeters of water (mm H
2
O). If SWX 6 is set to OFF, the
pressure is displayed in Pascals.
SWX 7 – Initialize Defaults
This switch is not implemented and must remain in the OFF position.
SWX 8 - Program ‘A’ or ‘B’
This switch is used to toggle between 2 preset programs. This could be
used to store separate summer/winter programs for instance. The ON
position is for Program A, and the OFF position is for Program B.
