-control lighting, blinds and scenarios

-PID controller for room temperature or ventilation (KNX S-Mode)

LCD display of temperature, speed, etc. -LCD display of temperature, rpm, etc.

-Labels for lighting, blinds, scenes (interchangeable, created with a Word template)

-control via 8 or 16 keys

-KNX interface (S-Mode and LTE-Mode) and KNX PL-Link (for TRA with Plug&Play function)

-Power supply via KNX/KNX PL-Link bus

-LED for displaying the switching status or as orientation indicator

Scope of application/compatibility

- Use with KNX PL-Link:

The space management controller determines the functions of the keys and the LCD display.

Measurement and indication of room temperature, humidity and CO2

Control of room functions

Display of external information (outside temperature, outside air humidity, status of a window contact)


- Use with KNX S-Mode

Measurement and indication of ambient temperature, relative humidity, CO2 concentration, etc.

Display of external information: Outside temperature, outside air humidity, status of a window contact

Room temperature control (with PID controller)

Control (threshold switch) of relative room humidity, CO2 concentration, etc.

Switch: Switching and dimming of lighting, blind control, calling up and saving of scenes

- Use with LTE KNX-Mode

LTE mode can only use information from QMX3.P30 and QMX3.P70 models.
