Wiring Diagrams
The following diagrams illustrate the electrical connections for the ECL Comfort 200 and ECL Comfort 300 controllers, covering configurations for both 230 V a.c. and 24 V a.c. power supplies.
230 V a.c. Supply
ECL Comfort 200 (230 V a.c.)
Power Input: Connect 230V AC to the L (Line) and N (Neutral) terminals.
Bus Communication: Utilize the BUS terminals for network connectivity.
Input/Output Terminals:
- Terminals 1-5: Typically used for sensors or digital inputs (e.g., S1, S2, S3, S4).
- Terminals 9-12: Relay outputs (e.g., TR1, TR2).
- Terminals 15-20: Analog inputs/outputs (e.g., R1, R2).
Optional Connections: RS232 interface (available at the rear or front if a specific module is mounted), LON interface.
ECL Comfort 300 (230 V a.c.)
Power Input: Connect 230V AC to the L (Line) and N (Neutral) terminals.
Bus Communication: Utilize the BUS terminals for network connectivity.
Input/Output Terminals:
