quick reference shown on the next page. Each of the numbers are also 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.
Look at the stage status indicators. If the light for stage 1 is lit, the parameter you are programming is for
stage 1. To go to stage 2, continue to press the mode button until the stage 2 stage indicator light is lit.
6.1 Stage Programming
The following parameters are used to program each stage on the Farm Hand SC-5v2. Through
these parameters, the user has complete control over the operation of each stage. The following
sections explain each parameter in detail.
P1 = Stage Sensor
P2 = Stage Mode
P3 = Timer Status
P4 = Stage ON Temperature
P5 = Stage OFF Temperature
6.1.1 Stage Sensor (P1)
The SC-5v2 triggers stage operations from temperature sensors. The stage sensor parameter (P1)
sets which sensor(s) the controller uses to regulate stage operation.
P1 options are as follows:
10 = Sensor 1
Sensor 1 is used. The controller will ignore sensor 2.
02 = Sensor 2
Sensor 2 is used. The controller will ignore sensor 1.
12 = Average of Sensors 1 & 2
The average temperature of sensor 1 and sensor 2 is used.
6.1.2 Stage Mode (P2)
The Farm Hand SC-5v2 is a very intelligent controller, therefore, it needs to not only know
whether this is a heating or cooling stage but also what type of cooling stage. The Farm Hand SC-
5v2 reacts not only to temperature but also curtain position. This feature allows the grower to
program the cooling stages to work exactly like he wants them to without the expense of hard
wiring through relays and limit switches. This feature allows the Farm Hand SC-5v2 to better
react to the environment. Any Stage can be programmed to be one of the following:
