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.
