Hired-Hand Farm Hand Series: Stage Master - Manual (Page 19)

Part No. 4801-0151 Rev 4-06 Farm Hand Stage Master 19 of 40
Brief Description of Progressive Cool Timer Option
As you can see from graph 3, as the temperature increases above the Minimum OnPoint,
(OFF=75ºF) the Runtime % progressively increases until it reaches 100% at its Maximum OnPoint
(ON = 80ºF). When using this option, it is not necessary to set P10 or P11 for the stage. These
parameters only apply to variable speed operation.
10. Maintenance
Check the calibration of your sensors at least once per quarter. To do this, you will need to have two
persons: one at the sensor with a trusted thermometer, and one at the controller to set the sensor to the
proper setting.
11. Wiring Diagrams, Schematics, etc.
All wiring connections for stages, curtain machines, variable speed
fans, and curtain sensors inside the controller are made without
terminals on the end of the wire. To make the connection, strip about
¼” of the insulation off the wire, and follow the diagram below.
1. Insert a small screwdriver into either the hole shown in the
diagram.
2. Insert the stripped end of the wire into the hole shown in the
diagram.
3. Remove the screwdriver, and tug slightly on the wire to check
that it is snug.
Warning!
Do not connect more than 12 amps of load to any one stage. The Variable Speed
Circuit will carry up to 12 amps.
