Operation
Turn On Backlight
Pressing any button turns on the backlight, which
will remain on until about nine seconds after the last
button press.
Change Setpoint
To change the setpoint, push the Setpoint button to
display the current value. Use the Up/Down buttons
to change the value. After the display reverts back
(after about nine seconds) to displaying the room
temperature, the thermostat will control at the new
setpoint.
NOTE: After a power loss, the setpoint will revert
to the default value (70° F or 21.1° C is the
factory default). This default value is also
used in the deadband unoccupied mode. To
change the default value, see Configuration
on page
3.
Start Unoccupied Mode
Flip open the cover (hinged on the left side) and
momentarily push the UNOCC button. The thermo-
stat will stay in Unoccupied mode until the Setpoint
button or one of the Up/Down buttons are pushed.
NOTE: There are two unoccupied mode options,
Off (the default) or Deadband. See
Configuration on page
Toggle Between °F and °C
To temporarily view the other temperature scale, flip
open the cover (hinged on the left side), and momen-
tarily press the F/C button. The alternative scale will
appear as long as the backlight is on.
To make the desired F or C scale mode permanent
(the scale persists instead of being momentary), press
and hold the F/C button down for approximately 10
seconds until the display begins to flash. To return to
the previous scale mode, repeat the process.
