-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.
