Installation
- Remove the cover from the base at the bottom of the device.
- Position the sensor base vertically on the wall 1.35 m (4.5ft.) above the floor with the “UP” arrow facing upward. Locate away from windows, vents, and other sources of the 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.
