We now must pick the appropriate ranges, according to our devices, so that the values being displayed will be meaning-
ful for that partiuclar input. To do this, click on the box under the range column, representing which input you want to
adjust. For input 1, the arrow on the picture at the bottom of the previous page is where to click. A pop up window will
appear. We are using a DTS-FL-4-6-7 temperature sensor, for input 1, which is a 10K Type 2 thermistor, so we will need
to select that option, which is circled in green in the picture below. For input 3, we have a differential air pressure switch
that is a closed circuit at normal conditions. We can use the same method, as we did for input 1, and select option 3, “On/
Off” for input 3’s range so that when the switch is at normal condition it reads “off” and when it gets triggered it reads “on.”
This is up to preference however. If you want the normal condition to be “on” and “off” to be when the switch is activated,
you would select option 5.
After the inputs have been set up correctly. The input screen should now look like the screen below.
We will now demonstrate how to properly con fi gure an output port to achieve a two stage heating and two stage cooling
con fi guration with a single speed fan.
To set up the two stage heating and cooling, navigate to the Con fi guration button, circled in black in the picture located
at the top of the next page, and then select “PIDs table”, circled red in the same picture, to get to the desired window.
A “PIDs Set Dialog” window will display, following the step 14, showing three PID tables. Only the fi rst PID table is impor-
tant for us. The screen capture located at the bottom of the next page shows the important points for our example. Notice
that both the values of the “Heating Stages” and “Cooling Stages”, indicated by the red arrows, need to be changed from
3 to 2 for our example.
As speci fi ed as our goal in step 13, we will need to set the number of fan speeds to just one. This will be done using the
“#Modes/Speeds” menu which is circled in blue in the picture at the bottom of the next page. The last step to be done
is to select an appropriate mode for the PID table. The menu list for this is highlighted by the green arrow on the same
picture. We chose “Fan Aut” which stands for automatic fan and will allow both heating and cooling modes. We are now
fi nished with con fi guration. Close the “PIDs Set Dialog” window and then the “Parametor” window using the “Exit” buttons
relative to the windows.
