Scenes is a feature that your installer selects when he sets up each thermostat in your system.
Please refer to the Job Record J 545 for a record of how your installer made these settings
Scenes allow you to change the temperature of all the thermostats that use the Scene feature from a single thermostat.
Several of the Scenes are preset from the factory. However, your installer can customize several of the scenes based on your needs.
Refer to the Scene table below for a description of each scene.
| Scene | Description | Thermostat Operation |
| 1 | Permanent 1 | Scheduled event, Wake, Unoccupied, Occupied, Sleep, Away |
| 2 | Permanent Away 2 | Away DHW demands are ignored (applies to reset modules) Setpoint demands operate (applies to reset modules) |
| 3 | Permanent Unoccupied 3 | Unoccupied |
| 4 | Permanent 4 | Scheduled event, Wake, Unoccupied, Occupied, Sleep, Away |
| 5 | Permanent 5 | Scheduled event, Wake, Unoccupied, Occupied, Sleep, Away |
| 6 | Temporary Occupied 6 | Occupied for 3 hours |
| 7 | Temporary 7 | Scheduled event, Wake, Unoccupied, Occupied, Sleep, Away for 4 hours |
| 8 | Temporary 8 | Scheduled event, Wake, Unoccupied, Occupied, Sleep, Away for 8 hours |
To select a scene:
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.
| Location | Scene | Temperature |
| Master Bedroom | 1 | Schedule |
| 4 | Schedule | |
| Guest Bedroom | 1 | UnOccupied |
| 4 | Schedule |
