Scenes Section N
Scenes are a function that is available on the thermostat.
•
• To use the scene function, go to the Scene menu and
set the Scene setting to On.
Scenes are a method of changing the temperature throughout
an entire building from a single thermostat. A permanent
scene remains in place until another scene is selected.
When a temporary scene is selected (Scenes 6, 7, 8), a
timer counts down and when it times out, devices return
to the last permanent scene selected.
See the Scene table for details regarding the timing of
Scenes. There are a total of eight Scenes available.
• • Default Scene: The default scene is Permanent 1. In a
typical installation, the thermostat will be set to follow
the scheduled event in the Permanent 1 scene.
• • Factory Set Scenes: Scenes 2, 3 and 6 are factory set
and force the thermostat to the Away, Unoccupied or
the Occupied temperature respectively.
• • Customizable Scenes: You can customize Scenes 1, 4,
5, 7, and 8 to either follow the scheduled event, or the
temperature can be forced to the Wake, Unoccupied,
Occupied, Sleep, or the Away temperature.
Note: If no schedule is available, the Scene menu selections
are limited to Occupied and Away
