9.5 Min/Max Mode
This mode displays the recorded minimum and maximum temperature and
humidity values.
1. Select the sensor with CHANNEL.
2. Press MIN/MAX to toggle between the normal display, the minimum
and the maximum values.
10. Guidelines for Wireless Devices
Wireless communication is susceptible to interference, distance, walls and
metal barriers.
Electro-Magnetic Interference (EMI)
Keep the thermo-/hygrometer away from monitors, computers, etc.
Radio Frequency Interference (RFI)
Keep the thermo-/hygrometer away from other devices using the
433 MHz frequency.
Line of Sight
The thermo-/hygrometer has a range of 100 m (no interference,
barriers or walls). Considering all obstacles, the range will be about
30 m.
Metal Barriers
Radio waves will not pass through metal such as aluminium.
Consider all metal barriers when installing the sensors.
11. Troubleshooting
The thermo-/hygrometer does not display any value.
The signal has been lost or is not yet found. Pair the thermo-
•
/hygrometer with the sensors.
The signal cannot reach the thermo-/hygrometer. Remove all
•
obstacles between the devices or reduce the distance between
them.
The batteries are exhausted. Replace the batteries in the
•
thermo-/hygrometer and/or the sensors.
The indoor and outdoor temperatures do not match.
The thermo-/hygrometer and/or the sensors are not stabilized
•
yet. Allow 30 minutes for the devices to optimize data
transmission.
The thermo-/hygrometer is not calibrated. Refer to chapter
•
8.3 Calibration.
