Essential facts in brief
programming unit is waterproof (IPX7) and can therefore also
be used whilst showering or bathing. The range of the wireless
programming unit is approx. 25 m within the building.
In addition to the wireless programming unit of FFB 1, up to 5
further wireless programming units FFB 2 can communicate with
the receiver module in the instantaneous water heater.

Essential facts in brief

electronic comfort
Temperature selection – between 30 °C and 60 °C, adjusta-
ble in 0.5 °C stages
Memory buttons – Allow the user to save and recall two
preset temperatures
Changing the battery
Since each wireless programming unit has an individual transmit-
ter code, each FFB 2 must first be paired with the receiver module
(see FFB 2 Initial start-up).

With FFB 1, the transmitter code of the wireless programming
unit is already paired.
5. Operation
The wireless programming unit is normally in power saving mode
(display switched off). Briefly pressing any button will activate the
programming unit. If no button is pressed within 20 seconds when
the unit is activated, the programming unit automatically switches
back to power saving mode.
If the programming unit is activated via the
last set value is displayed and transferred to the instantaneous
water heater. The set temperature can then be changed by individ-
ually pressing the buttons in 0.5 °C increments or holding
down and scrolling up or down.
When activating the unit by pressing memory buttons
corresponding stored value is displayed and transmitted. This lets
you simply and quickly select a frequently used preset temper-
ature.
Each change to the set value that the instantaneous water heater
accepts is confirmed by an audible signal (beep) from the receiver
module installed in the instantaneous water heater. This signal
can be deactivated by the contractor at the customer's request.

Saving temperature to memory buttons

To reconfigure the memory buttons, select the desired set value
on the display then press the corresponding memory button for
approx. 3 seconds. The display will briefly fade out to confirm the
temperature has been saved.
If using several wireless programming units, each wireless pro-
gramming unit has two dedicated memory cells. As a result
on each wireless programming unit and on the instantaneous
water heater can all be assigned individual settings.
5.2

Dynamic anti-scalding protection

If several wireless programming units are being used, priority for
setting the maximum temperature values is automatically given
to the first programming unit to transmit a signal. This priority
is available for two minutes or until two minutes after the end of
the current draw-off and is then automatically disabled again.
During the priority phase, the other wireless programming units
can only reduce the temperature. If this temperature is reduced
to ≤ 43 °C, the dynamic anti-scalding protection is activated; this
prevents any wireless programming unit from increasing the tem-
perature above 43 °C for this draw-off event. Example: If a tem-
perature value of, for example, 55 °C is shown on the display of a
wireless programming unit and transmitted to the instantaneous
water heater, the instantaneous water heater increases the water
temperature to just 43 °C.
If several wireless programming units are being used at the same
time, the actual set temperature may differ from that shown on the
display of the wireless programming unit. Only the wireless pro-
gramming unit that is currently active displays the current value.
Outlet temperatures in excess of 43 °C lead to a risk of scalding.
