Operation
Operation modes
Figure 1. Operation Modes.
Normal Mode
In Normal Mode, the display is updated with
temperature and humidity, (where applicable) on a set
time cycle.
The display shows temperature in units of degrees
Fahrenheit, or in degrees Celsius if the jumper (resistor
R64) on the printed circuit assembly (PCA) is clipped
(See Setup of Displayed Temperature Units).
Depending on the model, the humidity is displayed as
well. When both of these variables must be displayed
(temperature and relative humidity) the display will
cycle through the required values at a rate of one
change every three to five seconds.
Override
These room units provide a dry contact closure
function, which may be used to signal the controller to
change the night setback or occupancy state. The
contact is made by pressing the override button (button
designated by an image of a man inside a house).
When the button is pressed, the word OVERRIDE
appears in the display. After three seconds, the text
disappears.
