Installation and Commissioning
Charging the internal energy storage
Wireless room radio sensors are supplied with energy from ambient light converted to electricity by means of integrated solar cells. An
illuminance of 500 lx should be available for 4 hours for charging. Excess energy is used for charging the internal energy storage in order to
ensure proper operation during periods of insufficient or absence of ambient light.
The sensor reaches its full operating runtime capacity in the dark not until the internal energy storage is completely charged. This may take
several days, depending on ambient light intensity conditions. Runtime capacity in the dark is depending on the transmission interval and the
charging state of the energy storage.
Inserting an additional battery
In poor lighting conditions, two batteries of the type: 1.5 V R03 (AAA) can be inserted into the battery compartment. The batteries serve as a
back-up if the power generated from the ambient light is not sufficient. Observe the correct polarity when inserting the batteries! To activate
battery operation, toggle the switch on the rear side to position “B”.
Setting frequency of transmission
A wireless room radio sensor sets off a radio telegram in fixed time intervals and at relevant changes of the measurand.
The wireless room radio sensor transmits its measured data event-driven:
A measuring cycle is initiated and a radio telegram is generated by pressing the “Learn-In” button or the presence pushbutton.
The wireless room radio sensor transmits its measured data time-controlled:
Use the rotary switch to create settings for the time-driven transmission cycle.
The various setting possibilities are shown in the table below:
Measurement cycle 1s Measurement cycle 10 s Measurement cycle 100 s
Transmission cycle:
Transmission cycle: Transmission cycle: Position 0:
every 7th to 14th measurement cycle
*
Position 1: at each measurement cycle Position 4: at each measurement cycle Position 7: at each measurement cycle
Position 2: every 7th to 14th measurement cycle Position 5: every 7th to 14th measurement cycle Position 8: every 7th to 14th measurement cycle
Position 3: every 70th to 140th measurement cycle Position 6: every 70th to 140th measurement cycle Position 9: every 70th to 140th measurement cycle
*
(default)
Whenever a measurand has changed significantly between regular two measurement cycles, a radio telegram with the current measurement
data is transmitted, regardless of the actual transmitting cycle settings.
Threshold values for changes causing a radio telegram transmission:
Changes in temperature > 0.2 K
Note: The settings for measurement cycle and transmission cycle have an effect on the device’s runtime capacity in the dark.
Learning-in of the transmitter
To establish a connection between transmitter and receiver and thereby to enable correct transmission of measurement data, it is necessary to
learn-in the respective room radio sensor at the corresponding receiver. This is done by pressing the “Learn-In” button at the room radio sensor
and by activating the learning mode at the receiver. The learning telegram includes manufacturer information and information on the type of
device and its function.
Further information on learn-in alternatives are found in the respective documentation of the receiver.
Transmission range of the sensor
The signal strength of radio signals is declining with the increasing distance between transmitter and receiver. The transmission range at line of
sight averages ca. 30 m in corridors and 100 m in halls. Transmission range of radio signals inside buildings is depending on the building materials
implemented on site:
Material-typical range of coverage:
– Masonry: 20 m, through maximum 3 walls
– Plasterboard ⁄ wood: 30 m, through maximum 5 walls
– Reinforced concrete: 10 m, through maximum 1 wall ⁄ ceiling
– Heat-insulating windows: 5 m, through maximum 1 window
Curtailment of the radio signal transmission range caused by:
– Installation of transmitter ⁄ receiver in the immediate proximity of materials containing metal components or metallic objects.
A distance of at least 10 cm should be observed.
– Mounting the receiver on the floor (floor box) or near the floor
– Moisture in materials
– Units also emitting high-frequency signals such as, for example, computers, audio and video systems, or electronic ballasts for illuminants.
A minimum distance of 50 cm should be observed.
