Sensor Set up
Note: To avoid permanent damage, please take note of the battery polarity before inserting the batteries.
Remove the battery door on the back of the sensor. Insert two AA batteries.
Figure 13
We recommend lithium batteries for cold weather climates, but alkaline batteries are sufficient for most
climates. We do not recommend rechargeable batteries. They have lower voltages, do not operate well at
wide temperature ranges, and do not last as long, resulting in poorer reception.
Replace the battery door. Note that the temperature and humidity will be displayed on the LCD display.
Looking at the back of the unit from left to right, the polarity is (-) (+) for the top battery and (+) (-) for the
bottom battery.
Sensor Placement
It is recommended you mount the remote sensor outside on a north facing wall, in a shaded area, at a
height at or above the receiver. If a north facing wall is not possible, choose a shaded area, under an eve.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although the
sensor is weatherproof, it is best to mount in a well-protected area, such as an eve.
1. Use a screw or nail to affix the remote sensor to the wall, as shown in Figure 6
2. Hang the remote sensor up on string, as shown in Figure 14.
