interconnecting wires are required between the main unit (receiver) and the remote sensors (transmitters).
Power up and test communications between all of the sensors and the main unit BEFORE mounting them outside.
· For most applications alkaline batteries are acceptable where temperatures remain above 32°F (0°C).
· At temperatures below 32ºF(0ºC) use lithium batteries otherwise transmission performance will be reduced or
interrupted
· Avoid using rechargeable batteries. (Rechargeable batteries do not provide correct power levels).
· ALWAYS install batteries in the remote sensors before the main unit. (Please read batteries installation instructions in
the manual for each remote sensor before installation)
· Insert batteries matching the polarity in the battery compartment
· Remove plastic sleeve from LCD display (if any).
· During an initial setup, place the main unit close to the remote sensors.
· After reception is established (all of the remote readings will appear on the main unit’s display), position the remote
sensors and the main unit within the effective transmission range. Ideally they should be placed within the line of sight
of the main unit. See placement tips in the user manual for each remote sensor.
· Transmission range may be affected by trees, metal structures and electronic appliances.
· The main unit must be placed indoors.
· The effective operating range may be influenced by the surrounding building materials and how the receiver (main unit)
and transmitters (sensors) are positioned.
· Place the remote sensors so that they face the main unit (receiver), minimizing obstructions such as doors, walls, and
furniture.
· Make sure that the remote sensors are easily accessible for cleaning and maintenance.
Note: When the temperature falls below freezing, the outdoor sensor batteries may have reduced voltage and a reduced
effective range. We recommend using lithium batteries at temperatures below 32°F (0°C).
IMPORTANT: We recommend cleaning the remote sensors periodically, as dirt and debris affects sensor accuracy.
