Selecting a Scene

Scenes are a feature that your installer selects when installing the setpoint control in the system.

Please refer to the Job Record J 162 for a record of how your installer made these settings.

Scenes allow you to change the system override on all thermostats and setpoint controls that have scenes enabled. The scene overrides the programmable scheduled temperature. This allows you to change the temperature of all the thermostats and setpoint control from a single thermostat or setpoint control.

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.

Note: If no schedule is available, the Scene menu selections are limited to Occupied and Away

To select a scene:

1. Use the Menu button to select the Scene menu.

2. Use the Item button to select the Select item.

3. Use the Up or Down button to select the desired scene.

• Default Scene: The default scene is Permanent 1. In a typical installation, a setpoint control follows the schedule.

• Factory set scene: When you select a factory set scene (2, 3, and 6), all of the setpoint controls and thermostats using the scene feature use the temperature specified

by the scene.

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

Example:

A house is normally in scene 1. There is a living room that operates on a schedule and there is a hot tub that is normally at the unoccupied temperature. When entertaining guests, the scene is changed to scene 4. Scene 4 has been pre-programmed to change the hot tub to operate at the occupied temperature.

Living room thermostat: Scene 1 is set to Schedule.

Scene 4 is set to Schedule. Hot tub setpoint control: Scene Permanent 1 is set to Unoccupied.

Scene Permanent 4 is set to Occupied.

After the Away Hold has elapsed, the setpoint control returns to its normal operation.

3. Use the Up or Down button to set the number of days

that you will be away.
