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, if this feature is set.
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 ALL 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 4 degrees.
Clock Display
The current time is displayed in the upper left corner of the main screen. Set the clock from the Users
Settings menu.
Outside Temperature Display
The outside temperature is displayed in the top center of the main screen. OT is only displayed if outside
temperature information has been sent to the thermostat from the network or a remote temperature sensor
set to address 4 is connected to the WDU.
Main Thermostat Screen Buttons
UP and DOWN Buttons
The UP and DOWN buttons control the setpoint temperature.
Pushing the UP button will increment the setpoint value by one degree and conversely, pushing the Down
button will decrement the setpoint one degree. Pushing and holding a button down will cause the setpoint
to continuously change until the button is released.
