Key Features:
- Ambient Temperature Sensor CRS 231
- Operating range: 10°C to 30°C
- Designed for ESBE S90 C-1 A controllers
3. Setup
The ESBE CRS 231 sensor is intended for integration into a heating system controlled by an ESBE S90 C-1 A regulator. Installation should be performed by qualified personnel in accordance with local electrical codes and the specific installation instructions provided with the ESBE S90 C-1 A controller.
Installation Guidelines:
- Placement: Select a location that accurately represents the ambient temperature of the area to be controlled. Avoid placing the sensor near heat sources (e.g., radiators, direct sunlight), cold drafts, or behind curtains, as these can lead to inaccurate readings.
- Wiring: Connect the sensor to the designated terminals on the ESBE S90 C-1 A controller. Refer to the controller's wiring diagram for correct connections. Ensure all wiring is secure and properly insulated.
- Mounting: Mount the sensor securely to a wall or suitable surface at an appropriate height, typically around 1.5 meters (5 feet) from the floor, to ensure optimal temperature sensing.
4. Operating Instructions
The ESBE CRS 231 sensor operates continuously once connected to the ESBE S90 C-1 A controller and the system is powered on. It measures the ambient temperature and transmits this data to the controller.
Functionality:
- The sensor provides real-time temperature feedback to the ESBE S90 C-1 A controller.
- The controller uses this information to adjust the heating system, maintaining the desired temperature set points within the 10°C to 30°C range.
- All temperature adjustments and system settings are managed directly through the ESBE S90 C-1 A controller interface.
For detailed instructions on setting temperature parameters, scheduling, and advanced system operation, please refer to the comprehensive user manual for your ESBE S90 C-1 A controller.
5. Maintenance
The ESBE CRS 231 temperature sensor is designed for reliable, long-term operation with minimal maintenance.
Recommended Maintenance:
- Periodic Inspection: Annually, visually inspect the sensor for any signs of physical damage, such as cracks, loose connections, or corrosion.
- Cleaning: Ensure the sensor's housing remains clean and free from dust, dirt, or debris that could obstruct its sensing capabilities. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Avoid Obstructions: Regularly check that no objects are blocking the sensor, which could lead to inaccurate temperature readings.
Do not attempt to open or repair the sensor yourself. If you suspect a malfunction or require service, contact qualified service personnel or ESBE customer support.
6. Troubleshooting
If you experience issues with your heating system that you suspect are related to the ESBE CRS 231 sensor, consider the following:
- Incorrect Temperature Readings:
- Verify the sensor's placement. Ensure it is not exposed to direct sunlight, drafts, or localized heat sources that could skew readings.
- Check for any physical obstructions around the sensor.
- No Response from Controller:
- Check the wiring connections between the sensor and the ESBE S90 C-1 A controller. Ensure all connections are secure and free from corrosion.
- Confirm that the ESBE S90 C-1 A controller is powered on and functioning correctly.
- System Malfunction:
- If the sensor appears to be functioning correctly but the heating system still malfunctions, consult the troubleshooting section of the ESBE S90 C-1 A controller manual.
- Contact a qualified HVAC technician or ESBE customer support for further assistance if the issue persists.
