TW2 Series Installation Guide
2. Position the sensor base vertically on the wall 1.35 m (4.5 ft.) above the floor with the “UP” arrow facing upward. Locate away
from windows, vents and other sources of draft. If possible, do not mount on an external wall, as this may cause inaccurate
temperature readings.
3. Pull 18 or 22 AWG cable(s) through the hole in the backplate.
4. Mount the backplate onto the wall using the screws provided.
Six screw holes available. Use a minimum of
two for secure mounting.
Connect the wires to the screw terminals. Do not over-tighten the screws.
