This manual covers the features and functions of the Siemens RDF30 room temperature controller with LCD display, including heating, cooling, fan speed control and energy‑saving modes. It provides detailed wiring diagrams, DIP switch settings, and control‑output assignments for four‑pipe fan coil units, direct‑expansion systems and valve actuators.
Installation instructions, parameter programming, sensor calibration, and safety certifications are described, along with technical data such as power supply, temperature range and accuracy. The document is intended for HVAC installers and service technicians.
| Power supply | AC 230 V ±10 % |
|---|---|
| Maximum power consumption | 6 VA |
| Output voltage (control outputs) | AC 230 V, max 5 VA |
| Operating temperature range | 5 °C – 35 °C |
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.
Enter calibration mode and modify parameter P09 to adjust the sensor reading until the displayed temperature matches a known reference.
Connect Q1, Q2, and Q3 to the three‑speed fan terminals; each output operates at AC 230 V with a maximum rating of 5 VA.
Set DIP4 to ON to activate the four‑pipe fan coil control mode.
