This does not involve any risk, i.e. it cannot lead
to an unwanted change in the setpoint tempera-
ture, but a transmitted temperature setpoint
may not be recognised by the receiver in these
circumstances. In cases such as these it is neces-
sary to repeat the adjustment.
1.3 Wall holder
The wall holder, which is included in the delivery,
can if required be fitted by the user in any
preferred location, to accommodate the radio
control unit.
2. Installation instructions
Before operating the instantaneous water he-
ater with a radio remote control, the receiving
module 3 must be fitted.
The DHE can be controlled by up to 5 additi-
onal FFB 2 radio control units.
Fitting of the receiving module and/or first
start-up of the FFB 2 must be carried out by
a qualified installer, under observance of these
installation instructions.

2.2 Provisions and regulations
• The operating and installation instructions for
the DHE instantaneous water heater are to
be observed during installation and operation.
• All electrical connection and installation
work must be carried out in accordance
with I.E.E Regulations, the provisions of the
electricity supply companies, and the ap pro-
priate national and regional provisions.
2.3 Unit installation
Observe the operating and installation in struc-
tions for the instantaneous water heater.
2.3.1 FFB1
The receiving module must be installed into the
DHE before the first operation of the FFB 1.
As soon as this is done the remote control
can be used.
To fit the receiving module (3) into the instan-
taneous water heater, work should proceed
as follows:
Switch off the power to the instantaneous
water heater
1.4 Care
A moist cloth is sufficient to care for the parts.
Do not use any abrasive or solvent-based clea-
ning agents.
1.5 Important note
The CE marking of our FFB radio remote con-
trols shows their conformity with the standard
requirements
– in accordance with the Law on Radio Installa-
tion Telecommunications Transmitter Devices
(FTEG) and Directive 1999/5/EG (R&TTE);
for the professional
Remove the cover of the instantaneous
water heater as described in the installation
instructions for the DHE;
Fit the receiving module into the top right
hand section of the back panel of the unit
with the connecting cable
to the bottom
(DHE .. SL) or to the front (DHE);
Secure the module in the DHE with the
screw provided. For the installation of the
module in the DHE .. SL the screw must be
removed;
Insert plug (10) of the receiver module into
the assigned space Adapter to the DHE .. SL
and for the DHE to the assigned space X2.
Please note that when fitting, the receiver
cable (10) must be positioned above the
existing cable (X1, position 7 on the DHE
installation manual);
Refit the cover of the instantaneous water
heater and connect the instantaneous water
heater to the power supply (observe the
installation instructions for the DHE).
No measures are necessary for fi rst start-up
of the FFB 1, this radio remote control func-
tions immediately after installing the receiving
module.
2.3.2 FFB 2
To activate the sender code of an FFB 2, this
must be transmitted once to the receiving mo-
dule when first start-up takes place.
On fi rst start-up of FFB 2-control units,
the DHE must be ready for service.
The following actions must be carried out
with the power switched on. After open ing
the cover, pay careful attention to live parts.
First start-up
Remove the cover of the instantaneous
water heater as described in the installation
instructions for the DHE;
Activate the learning mode by pressing
push-button (11) in the receiving module (3).
Therfore the module FFB of the DHE .. SL
has to be taken out of the plug-in position.
The activated learning mode is indicated by
the illuminated LED (12) in the receiving
module;
After 30 seconds have passed without a
transmission being received, the receiving
module automatically quits the learning
mode and the LED goes out;
Press any push-button on the new radio
control unit while the learning mode is
– in accordance with the Low Voltage Directive
73/23/EG;
– in accordance with the Electromagnetic
Compatibility Directive (EMV) 89/336/EG.
Keep these instructions carefully and
pass them on to your successor in the
event of a change of ownership.
In the event of any repair work, these in-
structions should be passed to the qualifi ed
installer for his attention.
activated. The LED blinks several times to
confirm the learning process, then goes out;
Checking option: a setpoint adjustment using
the radio control unit is confirmed by two
blinks of the LED, thus if the LED blinks only
once, the learning process must be repeated;
Refit the cover of the instantaneous water
heater
and in case the receiving module
(observe the installation instructions for the
DHE).
Further radio control units are brought into
operation in the same way.
If several radio control units are registered one
after the other, push-button (11) for activation
of the learning mode should be pressed anew
for each radio control unit.
2.4 Deactivating a radio re-
mote control
If a radio remote control unit is to be taken
out of service from one DHE, the following
steps should be taken to ensure safety in use.
The registration procedure on one of the
remaining remote controls must be repea-
ted 6 times as described in section 2.3.2
- 'First start up'. By so doing the specific
registration of the individual sender code
of the removed control will be over written.
If more than one radio remote control unit
remains, each of them must be re-registered
again as shown in 2.3.2
2.5 Deactivation of the
acoustic receiving signal
If the customer wishes to deactivate the
acoustic signal, the receiving module should be
opened and connector (13) pulled out.
If the signal later needs to be reactivated, it is
merely necessary to plug in the connector once
again.
2.6 Handover
Explain the functions of the unit to the user.
Make him or her aware of the safety instruc tions,
in particular. Hand over the operating and in-
stallations instructions to the user.
