Flush-mounted sensors and room operator units for KNX PL-Link QMX3.P35H..., QMX3.P38H... Communicating sensors, switches and room operator units with KNX PL-Link (for Desigo™ Room Automation) Functions (depending on type) ● 160 x 128 pixel touch screen ● Energy efficiency function (“Green Leaf”) ● Built-in room temperature sensor ● LCD display for room temperature, CO2, humidity, PM2.5, operating mode etc. ● User interface for lighting, blinds and scene control (QMX3.
Use / compatibility The room automation station determines the functions of both LCD display and touch screen. ● Measure and indicate the room temperature ● Display humidity, PM2.5, and CO2 ● Operate room functions ● Indicate external information (outdoor temperature, outdoor humidity) Mechanical design ● ● ● ● The devices are designed for a common conduit box (A). – Conduit box: Keep in mind the dimensions of the conduit box! The base plate (B) has screw holes for all common conduit boxes (A).
Notes Security CAUTION National safety regulations Failure to comply with national safety regulations may result in personal injury and property damage. ● Observe national provisions and comply with the appropriate safety regulations. Engineering ● ● ● ● ● ● The room operator units offer plug & play functionality. The room operator units receive power from the connected room automation station via the KNX PL-Link interface.
● Do not interchange the wires of the KNX PL-Link cable. – The red terminal is for KNX PL-Link + – The gray terminal is for KNX PL-Link – ● Observe all local installation regulations. CAUTION! The devices are not protected against accidental connection to AC 230 V. Operation Operational setting NOTICE Operation and display oft he room operator unit depend on the control program of the room automation station.

ABT is never connected directly to a room operator unit. When more than one QMX3.P... room operator unit is on the same trunk of the KNX PL-Link bus, manual commissioning is as follows: 1.
Maintenance NOTICE The device can be cleaned with off-the shelf, solvent-free cleaning agents. Do not use mechanical aids (rough sponge or similar materials) – only a soft, damp cloth. Disposal The device is considered an electronic device for disposal in accordance with the European Guidelines and may not be disposed of as domestic garbage. ● Dispose of the device through channels provided for this purpose. ● Comply with all local and currently applicable laws and regulations.
