Single mode

Up to 8 tap-action switches can be connected to the Tport of a bus module. In this mode each button only triggers one function depending on the press mode (short, long, release). Each button can store 3 commands (see button-functiontable). That adds up to 24 commands, controlling either groups of modules or single units. Since a variety of other sensors for light, temperature, pressure etc. can also be connected to the T-port, it should be mentioned here that only one of these sensor types can be connected. A tap-action switch adapter (LCN-TU4H) and a pressure sensor cannot be connected to one bus module. If sensors are attached, threshold values can be set to trigger specified actions. These values are also stored in the button-function-tables. The first 5 buttons are used for the threshold values.

Dual mode

This feature uses two buttons for one command and multiplies the amount of transmittable functions. For example: If a set of 6 buttons has been installed, 2 designated buttons become “function”-buttons and the other 4 become “selection”-buttons. The required command is triggered by pressing a selection-button and then the function-button.
