TS40 OPERATION
Wall display Unit Control Buttons
All 6 buttons on the TS40 Wall Display Unit are “Soft Keys” meaning that they change functions when you
change screens. The function of the buttons is defined by “on-screen labels” that are dynamic and change
when you change screens. The following are definitions for the buttons for the main “Thermostat screen”
and their primary mode of operation. Other screens and their button operations are defined in following
sections.
Wall Display Unit LEDs
The TR40 has four LED’s that display various status information. The LEDs have dynamic “on-screen”
labels that can change with the screen being displayed.
Wall Display Unit “Screens”
One of the unique features of the TS40 WDU graphical display is the ability to have multiple display
screens. In addition to a main thermostat screen, menus and other control screens for special functions
are provided. This makes an intuitive and easy to use “user interface”. It allows the many functions of the
TS40 to be easily navigated.
You move to other screens by pressing the Menu button from the main thermostat screen. A new Main
Menu “screen” will be displayed with a list of menu functions. When a menu item is selected, a new
“screen” will be displayed for that function. Refer to the individual screen descriptions that follow for
details on navigating each screen.
The Minimized Main Thermostat Screen
The main thermostat screen will go to a “minimized” screen after a timeout period. This presents a simple
uncluttered display of the current room temperature and outside temperature (if an OT sensor is attached).
Pressing any button causes the full Main Thermostat screen to be restored and displayed.
Screen Timeouts
When you menu to other screens, you have the option of exiting those screens to return to the main
thermostat screen or just waiting until the automatic screen timeout occurs that will return the display to
the main thermostat screen.
The main thermostat screen normally reverts to the minimized screen after 30 seconds. This can be
adjusted from 15 to 127 seconds in the User Settings Menu under Screen Timeout. You can also set the
timeout period to “0”. In this case the Main Thermostat screen will NEVER timeout and revert to the
minimized screen.
