Program Mode
By pressing and holding the
Mode
button for at least 5 seconds, the
S
3
can be placed in the
Program Mode
as
discussed below and on the following pages.
Settings that are usually set up once per grow-out or maybe even just for summer or winter are referred to as
program parameters and are accessed by taking the controller to program mode. To get to program mode, press and
hold the “Mode” button for five seconds. When the controller has entered program mode, the Zone 1 display will
show the first parameter (P1) and the Zone 2 display will show the current setting of parameter P1 (either C or F).
The “
Pxx
” is known as a parameter number. All the program items for the controller have a unique parameter
number assigned to them. The numbers are listed in the following subsections with a short description of each
parameter. When in program mode, you change the value of certain parameters 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.

General Parameters
General parameters are associated with the operation and control of the
S
3
:
P1 – Temperature Limits
This general parameter selects either Celsius (C = Celsius) or Fahrenheit (F = Fahrenheit) temperature
units. If P1 is set to “C”, the temperature units will be displayed in Celsius. If P1 is set to “F”, the
temperature units will be displayed in Fahrenheit.
P2 – Individual Sensor Limits
This general parameter determines how to program the Sensor High and Low temperature limits. As
indicated earlier, these limits can be set individually to different values. However, if it is desired to set
Sensor 1, Sensor 2, and Sensor 3 to the same values, this parameter changes the programming
procedure to allow limits to be entered only once but used for all sensors. If P2 is set to “
YES
”, the
high and low sensor limits are entered individually. If P2 is “
NO
” limits are entered once for all
sensors. To change the value of P2, press the Plus (+) button for “YES” or the Minus (-) button for
“NO”.
