Install the sensor in a vertical position in a place where the temperature sensor is not exposed to the sun.
Install the sensor in an easily accessible location to ensure easy maintenance (replacing batteries)

MOUNTING AND FASTENING THE THERMIS WIREFREE™ II IO

( Figure D

Drill two holes (6 mm in diameter) one below the other and approximately 17 mm apart.
Fasten the wall bracket using the screws provided, ensuring that the word “UP” is legible with the arrow pointing upwards and the water evacuation hole at the bottom (2).
Place the Thermis WireFree™ II io on the wall bracket with the two arrows aligned and then turn it clockwise to lock it in position.
If the sensor is not mounted straight:
Open the sensor by turning it anti-clockwise.
Loosen the screw in the oblong hole and turn the wall bracket.
Tighten the screw again and fasten the sensor to the wall bracket.
