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 480 has 3 User Buttons and 3 demand inputs.

The 3 User Buttons provide the ability to:

1) Select a scene for the tN4 system

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

Perm Scene 1 No Change

Perm Scene 2

- Away

Perm Scene 3

- Unoccupied

Perm Scene 4 Selects Scene 1

Perm Scene 5

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.

2) Provide a setpoint device enable

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.
