BClose the control box cover.
BRe-assemble:
• the control box in the appliance
• all connections between the PCB
and the appliance
• lower cover in the control box
• holding bracket
• front cover panel.
4.3 Remote Control Activa-
tion
BMove the main switch on the
appliance to the 0 position.
BPress and hold key while at the
same time turn the main switch to
“ON” position (I).
LCD shows one number and one
rotating digit.
The number represents the remote
control which is to be registered, the
first remote control will be registered
with number “0”, the second with
number “1” and so on.
iBefore the remote
control will work it will
have to be activated,
using the procedure
described below, and
standing in front of the
appliance.

The rotating digit shows that the
electronics is expecting a registration.
BHold remote control in front of the
control panel on the heater and
press simultaneously remote control
buttons and until the
temperature indication is shown on
the remote control LCD.
BSwitch ON/OFF switch to “OFF”
position (0) and then back on (I).
BPress buttons and in
order to reach requested
temperature.
New remote control is programmed.
4.4 Hot Water Temperature
Adjustment by Remote
Control
BPress the buttons or on
the remote control (Fig. 6, pos. 2)
until the required temperature
appears on the remote control
display (Fig. 6, pos. 1).
BWhen the required temperature is
defined, turn on the hot water tap.
BThe required temperature will flash
on the remote control display.
BThe flashing will stop when the
required temperature is reached
(tolerance from selected set point -5
+ 3 °K).

Remote Control
Memorizing the water
temperature with the remote
control "Program" button
BPress the buttons or on
the remote control (Fig. 7, pos. 2), )
until the required temperature
appears on the remote control
display (Fig. 7, pos. 1).
BYou will now be able to memorize
this temperature by keeping the
"Program" button on the remote
7
Using the Remote Control

control (Fig. 7, pos. 3) pressed for 3
seconds.
Fig. 7 Memorising water
temperature
BOnly one temperature can be
memorized using the "Program"
button on the remote control.
BAt this point the remote control will
display the memorized temperature .
When the hot water tap is turned on,
the water heater will supply hot
water at the temperature memorized
on the remote control.
If the temperature was memorized
using remote control buttons (it is
possible to combine up to six remote
controls), it can only be modified whilst
hot water is flowing if the same remote
control is used again (see chapter 4.6
"Priority Function").
Using the "Program" button
(operation with memorized
temperature)
To operate the equipment with a
previously memorized temperature:
BPress the "Program" button on the
remote control.
The remote control display or control
panel will now show the previously
memorized temperature. When the hot
water tap is turned on, the water heater
will supply hot water after a few
seconds, at the memorized
temperature.
iApart from the
temperature that can be
memorized using the
"Program" button on the
control panel, a second
temperature can be
memorized on each
remote control using the
"Program" button, to
meet the needs of each
user.

4.6 "Priority" function
The equipment does not have a default
temperature setting and therefore has
no default "Priority" function.The
"priority" will be attributed
automatically by the first user who
selects or memorises (on the remote
control or on the control panel) a
temperature for subsequent use (e.g. a
shower).
Then, when the hot water is used (e.g.
for a shower), the control panel display
and remote control/s display will show
the symbol " ".
The temperature may only be modified
using the same buttons that
memorized it (depending on whether
the control panel or the remote control
was used).
The "Priority" function ends:
•5 minutes after the last use of the
hot water (return to basic set up).
•2 minutes after selecting/
memorizing the temperature if no hot
water is used immediately
afterwards.
Acquiring "priority”
Any user can acquire "priority" for
subsequent use of hot water, as
follows:
BMove main switch to position I.
BKeep button or button
pressed.
BSelect the required temperature.
BPress the "Program" button for 3
seconds to memorize the
temperature, if required.
BUse the hot water within two
minutes of acquiring "priority.
4.7 Error Messages
This device has an error message
system. Any anomalies will be
iTemperature cannot be
memorized or selected
using the control panel
buttons or even a
second remote control
when hot water is in use
(e.g. during a shower)
since the "Priority"
function will
automatically start up to
stop another user
modifying the
temperature when hot
water is in use.
i"Priority" cannot be
acquired whilst the hot
water tap is open.

indicated by an error code that will
appear on the display (Fig. 2, pos. 1)
and by a symbol indicating a "safety
block" (Fig. 2, pos. 7). The device will
be operative once again following the
elimination of the fault and after
pressing the reset button.
To identify the type of anomaly, consult
chapter 5 of the installation manual.
5 Maintenance
5.1 Replacing batteries
When batteries are flat, the symbol
(Fig. 2, pos. 5) will appear on the
display.
BRemove the two screws on the back
of the remote control.
BOpen the battery housing and
remove the flat batteries, then
replace with new batteries, ensuring
they are inserted correctly.
BClose the battery housing using the
two screws.
5.2 Cleaning
Use a damp cloth to clean parts of the
remote control. No abrasive or solvent-
based detergents are needed.
iCertify that the rubber
seal is correctly fitted
between both plastic
housing parts.
Warning:
flat bat-
teries must be
replaced.
Consequently, the
manufacturer is not
liable for any faults or
damage caused by
flat batteries.
Do not create litter
with flat batteries:
ensure they are
disposed of in the
specific refuse con-
tainers.
