The User Switch 481 has 3 programmable buttons that allow
users to easily change the operating scene or allow users
to enable / disable tN4 setpoint controls on a tN4 system.
Multiple User Switches are required if more than 3 scenes
or setpoint enable / disables are desired.
The 481 has 3 output relay contacts that allow for connection
to alarm systems or paging systems to alert service personnel.
The output relay contacts can also be used to indicate the
scene of the tN4 system to an automation system.
User Buttons 1, 2, and 3 allow for users to select the operation of the tN4 system.
Buttons A and B allow the installer to program the operation of User Buttons 1, 2,
and 3.

Sequence of Operation
Three User Buttons
The User Switch provides users with a simple interface to change the operating
scene of the tN4 system or provide an enable / disable to tN4 setpoint controls. The
481 has 3 User Buttons and 3 output relay contacts.
The User Buttons allow users to select the scene of the tN4 system. Each of the 3
User Buttons is programmed by the installer to select a particular scene on the tN4
system. The temperature of each tN4 thermostat in the system is pre-programmed
by the installer for each of the scenes. This allows users to change the temperature
of all the thermostats using a single button.
tN4 thermostats and tN4 setpoint controls must have Scenes turned to “On” in order
to respond to scene changes on the User Switch.
When a User Button is pressed, the green LED under that button turns on and
remains on until a new scene is selected, or the time for the selected temporary
scene expires.
When the current selected scene on the tN4 network is the same as the scene that
the User Button is programmed for, the button turns green.
When a selected scene is “On” and that User button is pressed again, the scene is
changed based on the following table:
Current Scene
Press the
Same Button
New Scene
Perm Scene 1No Change
Perm Scene 2 - AwaySelects Scene 1
Perm Scene 3 - UnoccupiedSelects Scene 1
Perm Scene 4Selects Scene 1
Perm Scene 5Selects Scene 1
Tmpy Scene 6 - OccupiedSelects previous perm scene
Tmpy S c ene 7Selects previous perm scene
Tmpy S c ene 8Selects previous perm scene
Application Examples:
Allows residential users to change the scene to 2 (Away) while going on vacation,
or select an occupied scene while entertaining guests.
Allows commercial users a simple way to allow staff to override the night setback
/ setup schedule on the tN4 system.
Each of the 3 User Buttons can be programmed to enable or disable one or more
tN4 setpoint controls on the tN4 bus. The installer programs a setpoint device enable
number for one of the User Buttons. In turn, the installer programs a tN4 setpoint
control with the same setpoint device enable number. This allows users to enable
or disable a tN4 setpoint control by pressing a single button. Multiple tN4 setpoint
controls can be enabled or disabled from the same User Switch button.
The tN4 setpoint control operates for the “Occupied Time” or until the User Button
is pressed once again to cancel the operation. The User Button is green when the
tN4 setpoint device is in operation. Should the tN4 setpoint control be unable to
operate, the button turns red for 5 seconds and then the button light is turned off.
See the tN4 Setpoint Control Data Brochure for more information on the setpoint
control operation.
Application Examples:
A user can remotely enable a tN4 setpoint control to heat a hot tub or sauna.
A user can remotely enable a tN4 setpoint control to heat a garage or
workshop.
3) Disabled Button
The User Button can be disabled so that it does not function when pressed.
In certain cases, the disabled button can be used to close the corresponding relay
contact. See the “Button Operation” section for more information.
