Normal Mode
In Normal Mode, the display is updated with
temperature, humidity, carbon dioxide, and/or occupied
status (all where applicable) on a set time cycle.
The display shows temperature in the desired units (as
set by the clipable jumper on the PCA). Depending on
the model, the humidity and/or carbon dioxide value(s)
will be displayed as well. When multiple variables need
to be displayed (temperature, relative humidity, and/or
carbon dioxide) the display will cycle through the
required values at a rate of one change every three to
five seconds.
