Main Thermostat Screen
The main thermostat screen is the default display screen and is the screen that is normally displayed on the
Wall Display Unit. It will revert to a minimized screen after 30 seconds of display.
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(+/- .5°C). The WDU will display temperatures from
-63°F to 191°F. NOTE: If averaging remote sensors are attached, the display will show the average
temperature of the sensors.
Setpoint Display
The heating and cooling setpoints are displayed next to the Setpoint Up/Down buttons. In the HEAT mode,
the Up/Down buttons change the heat setpoint. In the COOL mode, they change the cooling setpoint. When
in AUTO mode, the buttons change the last call’s heating or cooling setpoint. Note that the setpoints will
“push” each other if they are adjusted to get within the minimum Heat/Cool separation (delta T) setting. This
is normally 3 degrees.
Clock Display
The current time is displayed in the upper left corner of the main screen.
Outside Temperature Display
The outside temperature is displayed in the top center of the main screen, if outside temperature information
has been sent to the thermostat or a remote temperature sensor is connected to the WDU.
Main Thermostat Screen Buttons
UP and DOWN Buttons
