Viessmann Vitotronic 200 Outdoor Temperature Sensor Instructions

To install the Viessmann Vitotronic 200 Outdoor Temperature Sensor, first mount the sensor on an exterior wall that is not directly exposed to sunlight. Ensure it is sheltered from rain and moisture. Connect the wiring according to the installation manual, ensuring all connections are secure.
If the sensor is not showing accurate readings, check for obstructions or exposure to direct sunlight. Verify all electrical connections are secure and inspect the wiring for any damage. Recalibrate the sensor if necessary following the manufacturer’s instructions.
To test the sensor, compare its temperature reading with a reliable thermometer. If there is a significant discrepancy, check the installation location and wiring. Use a multimeter to check the sensor's resistance and compare it with the values specified in the manual.
The outdoor temperature sensor is designed specifically for use with Viessmann Vitotronic 200 systems. Ensure compatibility by consulting the boiler’s documentation or contacting Viessmann technical support.
The sensor should be inspected annually for signs of wear and tear, such as damaged wiring or mounting issues. Clean the sensor to ensure accurate readings and recalibrate if necessary.
To clean the sensor, gently wipe the exterior with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that can damage the sensor. Ensure the sensor is dry and properly secured after cleaning.
Symptoms of a faulty sensor include erratic temperature readings, the boiler system not responding to outdoor temperature changes, and error codes on the Vitotronic 200 display.
To replace the sensor, first turn off the power to the boiler system. Remove the damaged sensor by disconnecting the wiring and unscrewing it from the mount. Install the new sensor by reversing this process, ensuring all connections are secure and the sensor is mounted appropriately.
Yes, the sensor is designed to operate in a wide range of temperatures, including extremely cold climates. However, ensure it is protected from direct exposure to severe weather conditions to maintain accuracy and longevity.
Premature failure can be caused by exposure to harsh environmental conditions, incorrect installation, physical damage, or electrical surges. Regular maintenance and proper installation can help prevent these issues.
