Problem
Solution
Wireless sensor not reporting into
console.
There are dashes (--.-) on the display
console.
If the signal from any sensor is lost, dashes (--.-) will be
displayed on the screen. To reacquire the signal, press
and hold the CHANNEL/+ button for 3 seconds,
choose the lost sensor and the remote search icon
will be constantly displayed. Once the signal is
reacquired, the remote search icon will turn off,
and the current values will be displayed.
The maximum line of sight communication range is
100m and 30m under most conditions. Move the
sensor assembly closer to the display console.
If the sensor assembly is too close (less than 1.5m),
move the sensor assembly away from the display
console.
Make sure the remote sensor LCD display is working
and the transmitter light is flashing once per 60
seconds.
Install a fresh set of batteries in the remote thermo-
hygrometer. 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).
Move the display console away from electrical noise
generating devices, such as computers, TVs and other
wireless transmitters or receivers.
Move the sensor to a higher location. Move the remote
sensor to a closer location.
Temperature sensor reads too high in
the daytime.
Make sure the thermo-hygrometer is mounted in a
shaded area. The pre preferred location is a north
facing wall because it is in the shade most of the day.
Indoor and Outdoor Temperature do not
agree
Allow up to one hour for the sensors to stabilise due to
signal filtering. The indoor and outdoor temperature
sensors should agree within 2 °C (the sensor accuracy
is ± 1 °C).
