Mounting/Positioning Remote sensor 

 

First: Place the remote sensor in the desired shaded location and the atomic clock in the 

home. Wait approximately 1 hour before permanently mounting the remote sensor to 

ensure that there is proper reception.  

 

POSITION 

Outdoor: 

 

Protect the remote sensor from standing rain or snow and from the overhead sun, 

which can cause it to read incorrectly.  

 

Mounting under an eave or deck rail works well. 

 

If you choose, you can construct a small roof or box for the remote sensor. Be sure a 

box has vents. 

 

Mount the remote sensor on the North side where to prevent sun from causing 

incorrect readings.  

 

Mount at least 6 feet in the air for a strong RF (radio frequency) signal. 

 

Do not mount the remote sensor on a metal fence. This significantly reduces the 

effective

 range

 

Remote sensors are water resistant, not waterproof.  

 

Indoor or Outdoor: 

 

Mount remote temperature sensor vertically.  

 

Avoid more than one wall between the remote sensor and the atomic clock. 

 

The maximum transmitting range in open air is over 200 feet (60 meters).  

 

Obstacles such as walls, windows, stucco, concrete and large metal objects can 

reduce the range.  

 

Do not mount near electrical wires, transmitting antennas or other items that will 

interfere 

with the signal. 

 

RF (radio frequency) signals do not travel well through moisture or dirt. 

 

MOUNT 

Option 1: 

 

Install one mounting screw (not included) into a wall. 

 

Place the remote sensor onto the screw (hanging hole on the backside). 

 

Gently pull down to lock the screw in place.  

 

Option 2:    

 

Insert the mounting screw through the front of the remote sensor and into the wall.
