• In some cases, the installer may have disabled a button. In this case, when the button is pressed,
the button will not turn green.

and Setpoint Controls will be discussed in upcoming sections.

Scenes
Scenes are system overrides. By changing the scene of
the tN4 system, all thermostats and setpoint controls with
scenes turned on are affected.
The button is green when the active scene on the tN4 system
and the programmed setting of the button are the same.
When there are no buttons programmed to the same scene
as the active scene, none of the buttons will be green.
Some scenes are permanent while others are temporary
and last for either 3, 4, or 8 hours. When a temporary scene
expires, the tN4 system returns back to the last permanent
scene. See the “Duration” column in the table to determine
the length of time the scene lasts.

When a button is green, and the button is pressed a
second time, it cancels the current scene. For permanent
scenes, the tN4 system returns to the “Normal” scene. For
temporary scenes, the tN4 system returns to the previous
permanent scene.
There are a total of 8 possible scenes available on the tN4
system. Each user switch can activate up to 3 scenes. In
order to be able to have all 8 scenes, multiple user switches
are required.

Example
A user switch has been installed together with two thermostats.
The thermostats are located in the master bedroom and
the guest bedroom.
User switch button 1 is labeled “Normal”.
User switch button 2 is labeled “Guest”.
User switch button 3 is labeled “Away”.
The master bedroom is programmed to operate at the
programmable setback schedule while in “Normal” and
“Guest” scenes.
The guest thermostat is programmed to operate at the
unoccupied temperature while in “Normal” scene and at the
programmable setback schedule while in “Guest” scene.
Setpoint Controls
In this example, when a guest arrives to stay the night, the
“Guest” button can be pressed and the Guest Bedroom
temperature will operate on a programmable setback
schedule.
Once the guest leaves, press the “Normal” button to lower the
Guest Bedroom to the unoccupied temperature setting.
The following table shows how the thermostats respond
to each button:
Button

Guest Bedroom

“Guest” Setback Schedule Setback Schedule
“Away” Away Away
In addition to scenes, the user switch can also be programmed
to enable and disable individual setpoint controls or groups
of setpoint controls by pressing the user switch button.
These controls can regulate the temperature of devices
such as a hot tub or a radiant floor.
When a user switch button configured for setpoint controls
is pressed, the setpoint control changes the operational
setpoint from the unoccupied to the occupied temperature.
The setpoint control has a timer setting that counts down,
and when the timer expires, the setpoint device changes
back to the unoccupied temperature. Also, if the user switch
button is pressed a 2nd time, the setpoint device operation
changes back to the unoccupied temperature.
