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 6. Scene 6 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 6 is set to Schedule.
Hot tub setpoint control:
Scene 1 is set to Unoccupied.
Scene 6 is set to Occupied.
Scenes are a system override feature available when the setpoint control is part of
a tN4 system. Scenes allow the user to change the entire tN4 system to operate at
preset temperatures.
To use the scene function, go to the Scene menu and set the Scene setting to On.
The tN4 scene can be changed through the scene menu on a tN4 thermostat, a
tN4 User Switch or through a tN4 Gateway. The setpoint control reacts to the scene
as follows:
Living Room Living Room

2 Away
3 Unoccupied (no effect if schedule is Off)
4 Not valid, remains at previous scene
5 Not valid, remains at previous scene
6 3 hour Occupied
7 Not valid, remains at previous scene
8 Not valid, remains at previous scene
The default is for the tN4 system to remain in Scene 1.
During the Unoccupied and Away periods, the Setpoint, DHW tank, and the Floor
are not heated.
During the Unoccupied period, the Hot Tub is heated to the Occupied temperature
minus 10°F (5.5°C). While in the Away scene, the Hot Tub is maintained at 50°F
(10.0°C).
