2. Do not move the main station or the outdoor sensors during the signal connection and reception process.
3. The sensors must be set up within a maximum of 100m from the main station with no obstacles.
TROUBLESHOOTING TIPS
To re-connect the signal of a sensor, follow these steps:
If the values displayed on the main station and the sensors are different,
you can try the following steps to troubleshoot:
Signal Connection Issues
If the main station does not receive an outdoor sensor signal within 3 minutes, it will stop
searching. The symbol (20) will disappear, and the corresponding channel will show values of
"--%" and "--.-℃".
1. Check the batteries of the sensor. If they are drained or weak, replace them with new ones.
Alternatively, you can remove and reinsert the batteries.
2. Move the sensor closer to the main station.
3. Press and hold the corresponding “ROOM” button (34/35/36) for a few seconds until the
symbol starts blinking again. The main station will start searching for the outdoor sensor
signal, regardless of whether the signal from the outdoor sensor was received or not.
1. Remove the batteries from the corresponding sensor.
2. Press and hold the corresponding “ROOM1/2/3” button on the back of the main station until the
signal reception icon (20) starts blinking.
3. Press and hold the corresponding “ROOM1/2/3” button (34/35/36) again until the value for the
corresponding sensor disappears from the display.
4. Install new batteries in the corresponding sensor and press the “TX” button above the battery
compartment.
The automatic clock signal reception function (radio control) of the product may be affected by
interference from signals in the end user's surrounding environment as well as too far from
the signal transmission tower, which may result in not receiving the signal and unable to
automatically adjust the time. In this case, the user needs to manually follow the steps in the
instruction manual to set the clock and date.
RCC Signal Reception Issue
Note: If the sensor value still does not appear on the main station, repeat the
above steps 2-3 times or move the sensor closer to the main station.
Several factors can interfere with the reception of the RCC signal:

RCC radio signal reception can be restarted manually by pressing and holding the “ ”
button (32) for seconds until the radio tower symbol (5) start blinking on the display and
the main station will start searching the RCC radio signal. If reception fails, the radio tower
symbol (5) will disappear.
1. Devices such as computers, telephones, radios, and televisions can emit electromagnetic
radiation that may affect signal reception.
2. Structural factors, such as reinforced concrete walls, thick brickwork, or long distances
between units, can also interfere with signal reception. Strong building insulation (such as
metal building materials), nearby mountains, or atmospheric interference can also be factors.
3. Low temperatures (below 0℃) can negatively impact the battery performance of the
outdoor sensor, thus affecting wireless transmission..
