Safety instructions
Observe the notes on mains supply. No other
form of mains supply other than specified in
these instructions may be used.
Conventional batteries must never be charged.
Danger of explosion!
Do not throw batteries into fire! Do not short-
circuit batteries!
Only operate device indoors and avoid influence
of humidity, dust, sunlight and heat.
Proper use
The LED sensor is used to collect current con-
sumption data at an electronic household meter.
Uses other than those specified in these operat-
ing instructions are not in accordance with the
intended purpose and lead to exclusion of war-
ranty and liability. This is also the case with mod-
ifications and conversions.
The values measured are not suitable for
purposes of public information. The device
is intended solely for private use and not for
invoicing.
The main meter is usually sealed and is the
property of the utility company. Modifications
are prohibited. If measurement devices are
installed, these must not influence the meter and
must be completely removable. The LED sensor
is designed to fulfil these requirements. No
modifications to the meter or mains supply
are required due to contactless, optoelectronic
determination of measurement data.
Functional description
The Gira LED sensor consists of a sensor unit
and a transmitting unit. The sensor unit registers
the flashing of the pulse LED of the electronic
household meter and passes the measurement
data on to the transmitting unit. This transmits
the data to the Gira energy and weather display.
The transmitting unit features an LED which illu-
minates when there is radio transmission. In nor-
mal operation, after pressing a button the dis-
play of the transmitting unit shows the average
power between the last two pulses for a period
of three minutes.
The sensor unit and transmitting unit are located
in separate housings for ideal positioning. In this
way the sensor unit can be positioned directly at
the electricity meter and the transmitting unit
can be positioned at a location with good radio
reception with the aid of a connection cable.

Inserting/replacing batteries
The sensor unit is supplied with voltage via the
transmitting unit. This is operated with four
alkaline batteries (1.5 V, type LR6, Mignon, AA).
Both sides of the transmitting unit have small
indentations to open the battery compartment.
1. Insert a screwdriver into the indentations and
pull off the battery compartment cover.
2. Insert four LR6 batteries with correct
polarisation into the transmitting unit.
3. Replace the battery compartment cover and
snap it in.

Using batteries
The LED sensor may only be operated with
alkaline batteries. Rechargeable batteries
must not be used.
"Empty battery" display
If the batteries are empty, bAt appears in the
display of the transmitting unit (alternating with
the normal display).
If this is the case, replace the station's batteries.
The assignment to the energy and weather
display is maintained when replacing the battery.
Assigning the transmitter
Radio components must be assigned to each
other to enable communication.
1. Press and hold  on the transmitting unit for
3 seconds.
The transmitting unit now transmits an assign-
ment signal every five seconds for the next
five minutes. The LED of the transmitting unit
lights up for the duration of this assignment
process.
2. Trigger the programming mode on the energy
and weather display within these five minutes
(see operating instructions for the energy and
weather display).
After start-up the transmitting unit displays its
version number as well as „kW" for 1 second.
This signalises that the sensor has been
assigned.
Following successful assignment the energy
and weather display then shows the electricity
meter data.
3. Pressing  again exits the programming
mode of the sensor.
A sensor can be assigned to any number of
energy and weather displays.
Deleting the assignment
Deleting the LED sensor assignment is only
possible on the energy and weather display.
