customize several of the scenes based on your needs.

Refer to the Scene table on the following page for a description of each scene.

scene.

•

Default Scene: The default scene is Permanent 1.

Custom scenes: When you select a custom scene, your installer will have preset
each thermostat using the scene feature to either follow its regular schedule, or
go to the set wake, occupied, unoccupied, sleep or away temperature.

Example:

A house is normally in scene

Permanent 1. There is a master

bedroom that operates on a

schedule and there is a guest

bedroom that is normally set

to Unoccupied. When a guest

arrives, the scene is to change to

Permanent 4. Scene 4 changes

the guest room to operate on the

setback schedule.
