DISPLAY ILLUMINATION
Shortly press key with light icon to switch ON and OFF the display illumination
DISPLAY AUTO OFF
Activate this mode in the setting menu to prolong battery life. Using this mode, the display switches OFF after 2 minutes of inactivity.
All other functions stay active. Display switches ON with each press of the key.
Also in display OFF state the LED signalize data reception.
SIGNAL RECEPTION
Reed LED blinks when the display unit receives a signal from the sensor (every 2 seconds if reception is good).
Signal strength is numerically shown in dB:
• -105 dB is approximately the limit where display unit stops receiving
• -100 dB and lower means very week signal
• -95 ... -90 dB is considered as still acceptable
• -85 dB and higher is a good signal
When the sensor doesn't send data (in OFF state) or when the signal is lost for a more than 2
0 seconds, the “dashes” appears on the
display, indicating that the receiver doesn’t receive data from the sensor (sensor OFF or out of range).
RANGE
Connection between sensor and display unit works on free 868 MHz band. Reach is up to 300 meters (1000 meters with extended
range sensor and longer antenna) - at 10 m sensor mounting height and when there is no obstacle between the sensor and the display
unit. Inside buildings the range is much shorter. Normally the signal can be received through two to three walls.
POWER SUPPLY
Unit can be battery or external powered, via micro USB connector. Built in Lithium 3 V battery ensures real time clock even in case of
power interruption or during battery changing.
BATTERY REPLACEMENT
Double blinks of LED diode marks that either - the sensor or the receiver battery should be changed.
Battery icon on LCD indicates the empty state of receiver batteries.
Alternating sign “S” with battery icon on LCD indicates the empty state of sensor battery.
Battery replacement of display unit:
Unscrew all 4 screws on backside of display unit enclosure and remove the back panel. Replace the batteries for display unit operation
(4 x 1,5V AA Alkaline) or for display unit real time clock battery back-up (1 x 3 V CR2032).
Place the rear panel of display unit in position and tighten 4 screws.
RESET OF DISPLAY UNIT
With middle button pressed while inserting batteries in display unit
– RESET is performed (all settings except »Sensor Address« and
»Calibration factors« goes to default values).
