• Select a user address from the physical point bar in the Control strategy
or Switching logic window.
• Type a user address name.
• Select a pseudopoint.
In the Control strategy function, click the desired pseudopoint in the
pseudopoint bar at the bottom of the window.
In the Switching logic function:
- Click menu item Software points.
The list of pseudopoint types displays.
- Click the analog type.
The Create/select software point dialog box displays.
- Click the desired point from the list. Click OK.
The pseudopoint address displays in the formula.
- Click End in the Create/select software point dialog box to close it.
RESULT: User address displays in the dialog box.
3. Enter values for the a1 through a7 coefficients in the editing fields. Enter as
many as there are user addresses for the x1 through x7 fields.

LIN Example If more than one sensor is in a room, not all the measured temperatures are equally
relevant to room comfort. You can use the LIN function to weight the values of the
sensors. In this example, there are three sensors with the following weights:
User Address Weight
Sensor_1 70 percent
Sensor_2 20 percent
Sensor_3 10 percent
Set up the LIN function with the following values:
a1=0.7 x1: Sensor_1
a2=0.2 x2: Sensor_2
a3=0.1 x3: Sensor_3
When sensor values are:
Sensor_1 = 76
Sensor_2 = 70
Sensor_3 = 68
The LIN calculation is:
