Placement Guidelines
Optimal placement ensures accurate readings and reliable wireless communication.
- Main Units (SC92 & SC93): Place indoors in a central location, away from direct sunlight, heat sources, and vents that could affect temperature readings.
- Wireless Outdoor Sensors:
- Mount the sensor in a shaded area, protected from direct sunlight and precipitation, which can cause inaccurate readings.
- Ensure the sensor is within the specified transmission range (up to 200ft in an open area) of its respective main unit.
- Avoid placing near large metal objects, electrical appliances, or thick walls that may interfere with wireless signals.
