What are the KNX E-mode main features?

The KNX Easy mode configuration is an alternative solution to the System Mode configuration. The E-mode does not require the ETS software, hence KNX E-mode devices can be set up without a computer.

There are 3 subcategories consisting of the E-mode.

Push Button Mode - PB-Mode

These configuration-type devices do not require tools or external devices for linking and configuration, meaning that the devices themselves support the configuration and link management procedures. The configuration mode that is activated is specific to each manufacturer (like a push of a button), and these devices bearing the KNX Certification Mark can be extended to S-mode devices (to be configured with ETS).

Controller Mode - Ctrl-Mode

A special tool, referred to as a controller is required to establish the links between the E-mode channels and set up the device's parameters. This mode is something between the S-mode and PB-Mode, making the Ctrl-Mode devices with KNX Certification Mark to be able to extend to S-Mode devices.

Logical Tag Extended Mode - LTE-Mode

This model is specially designed for HVAC applications, where the zoning information is named a Tag. The principle of this model is that devices with the same tags can work together, with those bearing the KNX Certification Mark able to extend to S-mode devices.

It is worth mentioning that E-mode and S-mode devices can coexist on the same KNX devices, enabling maximum flexibility.
