moisture.
• Do not place the sensor more than 30 metres
(98 feet) from the main (indoor) unit.
• Position the sensor so that it faces the main
(indoor) unit, minimizing obstructions such as
doors, walls, and furniture.
• Place the sensor in a location with a clear view
to the sky, away from metallic or electronic
objects.
