How to use

Mount the environmental sensor at a representative location away from direct heat sources, drafts and sunlight to ensure accurate ambient measurements. Connect the device to the AC 230 V mains following local electrical regulations and the system wiring diagram provided by your building automation or smart-home controller. After electrical connection, register or configure the sensor within the automation system so temperature readings are available for HVAC control, setpoint adjustments and automation rules.

Recommendations

For stable and accurate performance, position the sensor at chest height in the centre of the room where air circulation is typical; avoid installation near radiators, ventilation outlets or exterior walls. Periodic visual checks and adherence to installation guidelines in the system documentation will help maintain reliable operation.
