AVC Status
The AVC (Analog Value Comparison) Status Window is located in
the center of the GPC-XP Controller Status Screen (Figure 8, page
11). The GPC-XP has the capability to select the current Highest or
Lowest Reading or to calculate the current Average Reading from
selected Analog Inputs. These values appear in the AVC Status
Window. See Figure 71 below.
To select which Analog Inputs will be used for this AVC operation,
click <Setpoints> from the Toolbar located at the top of the GPC-
XP Status Screen. Then click
<Miscellaneous Settings> . The
Miscellaneous Settings Screen will open. See Figure 85, page 40.
In the AVC Inputs Window, select the Analog Inputs that you wish
to include in the AVC function. See Figure 72 below. Inputs not
selected will perform their normal confi gured function and will not
affect the AVC operations.
Outdoor Status
The Outdoor Status Window is located in the center of the GPC-
XP Controller Status Screen (Figure 8, page 11) and displays the
Outdoor Air (OA) Temperature, the OA Humidity, the OA Wetbulb,
and OA Dewpoint. See Figure 70 below.
If the OA Temperature and OA Humidity values are available, the
GPC-XP will always calculate the OA Wetbulb and the OA Dewpoint
values shown in this section. The values can be selected as Control
Source options when confi guring Relay Outputs and Analog Outputs.
For details on setting up the OA Temperature and OA Humidity
sources, as well as other related information, see the Outdoor Air
Broadcast section on the Miscellaneous Setpoints Screen on page 42.
