Signs of a Faulty Johnson Control Wall Mount Sensor
1. Inaccurate Readings:
Significant Abweichung from actual temperature or humidity: If the sensor's readings are consistently far off from what other thermometers or hygrometers show in the same location, it's likely malfunctioning.
Erratic or fluctuating readings: The readings on the sensor's display shouldn't jump around or fluctuate rapidly. This could indicate a faulty sensor or wiring issue.
2. Display Issues:
Blank or dim display: If the display is completely blank or very dim, even with fresh batteries, it could be due to a faulty display component.
Stuck pixels or lines on the display: If the display shows stuck pixels or lines, it's a sign of internal damage.
3. Physical Damage:
Cracks or dents on the housing: Physical damage can affect the sensor's performance and accuracy.
Loose or corroded wiring connections: Check the wiring connections for any signs of looseness, corrosion, or damage.
4. Functional Issues:
Occupancy override button not working: If pressing the occupancy override button doesn't change the temperature setpoint, it could be faulty.
Sensor not responding to configuration changes: If you're unable to change the sensor's settings through the DIP switches, there might be an internal issue.
