Operation
The various indicators and characters that are displayed on the LCD display are shown
in the Figure 16.
The front panel of the LCD display is used to perform the following functions:
•
Adjusting the deadband range
•
Turning on/off the occupancy override
•
Measuring the branch line pressure
3.1
Adjusting the deadband
NOTE: The deadband span can only be changed from the configuration menu on the
WPT-DB or from the WPT Web Console. The deadband span is the difference
between the "Cool Above" and "Heat Below" temperature.
The deadband may be shifted up or down using the ▲ or ▼ buttons. To change the
deadband range:
•
Press the ▲ or ▼ button once to view the current cool above and heat below
temperature (they will each flash once).
•
Press the ▲ or ▼ button to move the range up or down. Note that the span cannot
be changed from here.
•
Once the desired value is reached, press the OVR button to accept the change.
Leaving the display on the desired value for 5 seconds will also result in a deadband
change.
The LCD display will revert to the current temperature.
3.2
Turning ON/OFF the Occupancy Override
NOTE: This feature only works if the WPT-DB is in "Unoccupied" mode as commanded
by the scheduler.
To change the occupancy state from "Unoccupied" to "Override":
•
Press the OVR button to activate the occupancy override. The LCD display flashes
the override duration in hours.
•
Press the ▲ or ▼ button to change the override duration to desired value.
