    Troubleshooting Maintenance (cont.) 1. Pull plug "X3" from the control unit. 2. Test the resistance of the outside temperature sen- sor across terminals "X3.1" and "X3.2" on the dis- connected plug and compare it with the curve. 3. Where actual values deviate severely from the curve values, disconnect the wires at the sensor and repeat test on the sensor itself.

  • Page 93: Replacing The Flow Sensor

    Troubleshooting Maintenance (cont.) 2. Check the sensor resistance and compare it with the curve. 3. In the event of severe deviation replace the sensor. Danger The boiler water temperature sensors are immersed in the heating water (risk of scald- ing). Drain the boiler before replacing the sensor.
