Temperature display
The WDU will normally display the current temperature from the internal digital temperature sensor or a
remote sensor. The sensors have an accuracy of ± 1°F (± 0.5°C). The WDU will display temperatures from -40
to 190°F (-40 to 88°C). If averaging remote sensors are attached, the display will show the average temperature
of all attached averaging sensors.
Setpoint display
The heating and cooling setpoints are displayed next to the Up and Down buttons. In heat mode, the Up and
Down buttons change the heat setpoint. In cool mode, they change the cooling setpoint. When in auto mode,
the buttons change the last call’s heating or cooling setpoint. The setpoints will push each other if they are
adjusted to within the minimum heat/cool separation (delta T) setting. This setting is default set to 4 degrees,
but can be changed in the installer settings.
Clock display
The current time is displayed in the upper left corner of the main screen. Set the clock from the User settings
screen on page 12.
