2.3 Requirements and conditions
• The operating and installation instructions
for the instantaneous water heater should
be followed for installation and operation.
• All electrical connection and installation
work should be performed in accordance
with VDE specifications (0100), the require-
ments of the relevant electricity companies
and corresponding national and regional
requirements.
2.4 Installation of the FFB..SL
To install the radio remote control, also follow
the operating and installation instructions for
the DHE..SL (i).
2.4.1 FFB 1 SL
To start-up the FFB 1 SL , install the transceiver
module in the instantaneous water heater:
ð Disconnect the water heater from the elec-
tricity supply;
ð
Remove the heater’s cover as described in
the heater installation instructions;
ð Insert the module’s connector
E
(
10 ) into
the “Adapter” socket on the heater
(DHE..SL (i)). Place the module in the top
right of the heater’s back wall.
ð Fit the water heater cover and connect the
water heater to a voltage supply (Follow
the installation instructions for the instan-
taneous water heater).
No first start-up work is required for FFB 1 SL
as this radio remote control is operational
as soon as the transceiver module has been
fitted.
2.4.2 FFB 2 SL
To activate an FFB 2 SL radio remote control,
its transmission ID must be sent once to the
transceiver module so that it can be started up
for the first time.
When starting-up FFB 2 SL remote
control units for the first time the
instantaneous water heater must be ready
for operation. The following work must be
performed while it is connected to the elec-
tricity supply. Beware of live parts when
opening the heater cover.
First start-up
ð Remove the cover from the instantaneous
water heater (see installation instructions
for DHE..SL (i))
ð Activate radio remote control by pressing
any button. “CON” will appear on the
display.
ð Activate learning mode by pressing the
button (
11
) on the transceiver module (
3
)
(learning mode active is shown by the LED
(
12 ) on the transceiver module lighting).
After 30 seconds without receiving, the
transceiver module automatically leaves
2. Installation
for the qualified installer
learning mode (LED goes out).
ð The remaining learning mode time is
shown by the bar, running backwards, on
the remote control unit’s display. While in
learning mode, again press any key on the
new radio remote control unit.
ð The values set for the instantaneous water
heater are shown on the radio remote con-
trol unit’s display. The LED flashes briefly
to confirm the learning process.
ð Put the cover back on the instantaneous
water heater (follow the installation ins-
tructions for the heater).
Other radio remote control units are commis-
sioned in the same way.
If several radio remote control units are logged
in one after the other, the button (
11
) should
be pressed again for each radio remote control
unit to activate learning mode in the transcei-
ver module.
2.5 Logging out radio remote
control units
If a radio remote control unit is removed from
an existing system (one instantaneous wa-
ter heater with several radio remote control
units), the following procedure is required for
safety reasons:
ð Keep the button ( 11 ) on the transceiver
module pressed down for 5 seconds until
the red LED flashes. This deletes all trans-
mitter IDs from the memory;
ð Log the remaining radio remote control
units back in (see 2.4.2).
2.6 Hand-over
Explain the device’s functions to the user. In
particular draw his attention to the safety
instructions. Give the user the operating and
installation instructions.

ty”
