Dimensions
Functions
The TW2 Series sensor measures the temperature in a room and provides analog outputs to a controller
Installation
-
Remove the cover from the base at the bottom of the device.
-
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 -
Pull 18 or 22 AWG cable(s) through the hole in the backplate.
-
Mount the backplate onto the wall using the screws provided
Connect the wires to the screw terminals. Do not over-tighten the screws.
