Analog Types

Analog Output

Some of the most obvious point types are Analog Output (Setpoint) or (Reset Schedule), which are actually the same point type. By going to the point program screen on either of these points, you can convert the point to the other type by clicking a button. A Setpoint is pretty obvious, but a Reset Schedule is used to change your setpoint automatically, based on another input, like an Outside Air Temperature point. To set up a Reset Schedule, add the point and go to the Point Program Screen, then click on the Program Reset Schedule button. From the Reset Schedule Program Screen, you can choose your input point and temperatures.

Calculation

The Analog Input (Calculation) point type is mainly used to calculate a Setpoint Error or an average of several temperature points in a space. To configure this point type, go to the Point Program Screen and click the Program Calc button. The logic is programmed just like any other logic.

Meter

The Meter and Meter Total points are used in conjunction with pulse meter Counter points to convert the pulses into usable data like KWH or BTUs. Setting up these points is somewhat complicated and is another complete article. For complete instructions, see Chapter 7, Section 2, Pulse Meters.

Average

This point type gives you an average reading from any Analog Input that you choose. From the Point Program Screen, choose an input point to monitor, then choose an ‘Evaluate Every’ and ‘Average Over’ time. For example, if you choose to Evaluate Every 5 minutes and Average Over 1 Hour, every 5 minutes the point will give you the average reading over the last hour.
