Problem
Solution
Wireless remote (thermometer) not
reporting in to console.
There are dashes on the display console.
The maximum line of sight communication range is 300’
and 100’ under most conditions. Move the sensor
assembly closer to the display console.
If the sensor assembly is too close (less than 10’), move
the sensor assembly away from the display console.
Reacquire the sensor search mode (reference Section
6.3).
Install a fresh set of batteries in the remote thermometer.
For cold weather environments, install lithium batteries.
Make sure the remote sensors are not transmitting
through solid metal (acts as an RF shield), or earth
barrier (down a hill).
