Safety information and
implementation requirements
Application in private households only. The installation of this electrical devi-
ce is to be carried out exclusively by a skilled electrician.
The device must always be overcurrent protected by a 16 Amp circuit
breaker, which is to be switched off before installation. An upstream
connection to an RCD or an RCBO fault safety circuit breaker increases the
security level, but is not essential for the operation of the device.
Use approved phase indicators for no-voltage tests on the circuits.
Manipulations of the house consumer unit (fuse box) may cause perilous
electric shocks. Please precisely follow the connection instructions. Under
no circumstances allow the device to come into contact with water.
The enclosed label "Safety Information" is to be attached at a noticeable
position in the fuse box.
In the case of multi-installation of Demand Switches in one fuse box, they
must be mounted either on different bars or having a space and blanking
plate of at least half a unit (about 9mm) between neighbouring Demand
Switches.
Note: Please maintain these instructions in the fuse box in order to
have them at hand in the case of any potential questions arising in the
future!

Connection instructions
and functional test
Switch off the Main Switch for the electricity supply before installation.
Connect input "N" with the neutral conductor bar and input "L" with the out-
put of the desired circuit breaker. Switch on the main switch.
Conduct a functional test ( p r i o r to connecting the output phase to the elec-
trical circuit)
- Green LED "stand-by" ("betriebsbereit") must glow permanently.
- If "Autom." is switched on, the device must uncouple and switch the out-
put off.
Once again switch off the Main Switch. Connect the phase conductor of the
electrical supply circuit which is to be protected to the output "L". Switch on
the Main Switch. In the case of an inadvertent input polarity reversal, the relay
can clearly be heard toggling. If so, please check the connections and correct
them.

Brief instructions conside-
ring the initial operation
Install the Demand Switch according to paragraph 3 and conduct the functio-
nal test.
Switch off all lights and devices connected to the relevant circuit, also units in
stand-by mode (unplug them if need be).
Push "Autom." button until it engages:
After approx. two to three seconds the Demand Switch should uncouple ("dis-
connect") the respective mains section from the 230 V mains power supply.
This is indicated by the illuminated lower green LED ("230 V~: abgekoppelt").
Then plug the system control lamp included in the package into a clearly visi-
ble socket in the bedroom. This serves as a function monitor, as it only glows
in the case of voltage supply.
EA neon "night light" or a light or socket switch with a neon glow lamp will, in
contrast, also glow when a.c. voltage supply is disconnected, as the monito-
ring voltage of the Demand Switch allows both to be provided with DC volta-
ge (230 VDC, max. 8 mA or 1.8 watt load) uncritical with regard to the building
biology.
If the Demand Switch
doesn't disconnect...
First of all check whether the "Autom." button has been pushed and
has fully engaged. If the button shows "Autom.: aus", the electronic
system is bridged and the relevant circuit is supplied with voltage.
If the "Autom." button is pushed, but either one or both yellow LEDs are
illuminated, the relevant mains section has not been uncoupled and is still
supplied with mains voltage.
- If both yellow LEDs are illuminated, major consumer loads must be on
the line.
- If only minor consumer loads are on-line, the LED on the right (+) will
go out first, eventually followed by the LED on the left (-).
The Demand Switch will not uncouple until the left LED (-) has complete-
ly ceased to glow, also if it only glows very lightly. If in doubt, temporarily
disconnect the phase output "L" in order to repeat the functional test of
the Demand Switch (see par. 3). Should this test run successfully, one or
more permanent electricity consumers (such as electric clock or radio on
standby) must either still be connected to the ciricuit that you wish to pro-
tect, or the wiring is faulty and the leakage current rate is too high.
For further steps please see par. 6.
Permanent consumers
prevent decoupling
If the Demand Switch does not uncouple, there must be hidden electricity
consumers on the line which need to be disconnected, such as:
Permanent minor consumers (clock radio, sensor dimmer, antenna
amplifier, motion detector, clock timer, roller blind controls, refrigerator,
dishwasher, waterbed, thermostat for electrical heating, comfort telepho-
ne, fax machine, printer, scanner, etc.)
LBattery chargers (rechargeable shaver, toothbrush, telephone, game-
boy, etc.)
Stand-by units (hi-fi system, television, video-tape recorder, etc.).
All these devices consume power even when "switched off" so that it
would make sense in any case to disconnect them from the mains, for
example by using a switchable multiple socket outlet. When using single-
poled switchable multiple socket outlets it is important to pay attention to
the correct polarity (the phase must be disconnected!) - this will always be
the case if the wiring complies with the UK wiring regulations.
Further factors which can prevent decoupling may be too much leakage
current in the walls, too many light switches with glow lamps, or "baby
lights". The Comfort-series can "cope with" up to approx. 47 kOhm reduced
insulation resistance in the distribution network, which is considerably
lower than the test requirement to meet the IEE wiring regulations,
BS7671.
