After the main unit successfully displays the temperature from the outdoor
remote sensor, the synchronization of the main unit and the outdoor remote
sensor has been established. If the RF temperature signal is not received
within the first five minutes, press the RF search button (B6) on the main unit
to search for the remote temperature for another six minutes.
If the temperature is out of the measurable range, LL.L (beyond the minimum
temperature) or HH.H (beyond the maximum temperature) will be shown on
the display.
Press and hold the MODE button (B1) on the main unit to select the
temperature unit, either Celsius or Fahrenheit. Press the °C/°F button (D5) on
the outdoor remote sensor to select the temperature unit to be displayed,
either Celsius or Fahrenheit.
Losing Synchronization of the Outdoor Remote Sensor
If the main unit received the remote temperature successfully, but now
displays a blank value (—.-), the synchronization between the outdoor remote
sensor and the main unit may have been lost. If this occurs, press the RF
search button (B6) on the main unit. The main unit will attempt to receive the
outdoor temperature for six minutes and reinitiate synchronization with the
remote unit. If the remote temperature cannot be received, check:
1. If the distance between the main unit and the outdoor remote sensor is
at least 0.9 m to 1.2 m (3 to 4 feet) away from any interfering sources,
such as computer monitors or TV sets.
2. If the main unit is in the immediate proximity of metal window frames.
3. If other electrical devices, such as headphones or speaker, operating
on the same signal frequency (433 MHz) are preventing the correct
signal transmission and reception.
4. If neighbours are using electrical devices operating on the 433 MHz
signal frequency that are causing interference.
Note: When the 433 MHz signal is received correctly, do not open the battery cover
of either the outdoor remote sensor or the main unit, as the batteries may spring free
from the contacts and force a false reset. Should the batteries come out, reset both
units otherwise transmission problems may occur.
The maximum transmission range is 70 meters (230 feet) from the outdoor remote
sensor to the main unit (in open space). However, this depends on the surrounding
environment and interference levels. The temperature signal travels in a straight line
from the outdoor remote sensor to the main unit. The signal will not curve around
blocking objects. If no reception is possible despite the observation of these factors, all
units have to be reset.
Temperature Alert function
1. Press the ALERT button (B8) to activate or deactivate the outdoor
temperature alert function.
2. Press the ALERT button (B8) to:
a. Activate the outdoor upper temperature alert, the icon beside
the outdoor temperature digits will be displayed.
