Questions answered in these manuals
How do I change the temperature setpoint on the controller?
Press and hold the “+” and “‑” keys for 3 seconds, release, then press the “+” key again for 3 seconds; the setpoint (e.g., P01) will be displayed and can be adjusted.
How can I calibrate the temperature sensor if the displayed room temperature is inaccurate?
Enter calibration mode and modify parameter P09 to adjust the sensor reading until the displayed temperature matches a known reference.
What control output does the RDF300/RDF400 provide?
The RDF300 and RDF400 use an AC 230 V supply and provide on/off or three‑position control outputs.
