GENERAL INFORMATION
TO ENSURETHATTHEREMOTECONTROLPANELIS USED CORRECTLY, PLEASE
READ CAREFULLY THE ENTIRE CONTENTS OF THIS MANUAL.
WARNINGS
1) The remote control panel should be
installed in the room that is most easily
accessibleforcheckingthetemperature
of the environment (normally the
lounge).
2) To ensure correct operation of the
sensor, the control panel should be
positioned at a height of 1.5 metres
from the floor.
3) The control panel is supplied with low
voltage directly by the boiler. It also
contains a buffer battery, which has a
minimumlifeof 4yearsand guarantees
that the user settings are maintained
even when there is a black-out or a
break in the boiler connection.
4) It is essential that the control panel be
kept well away from heat sources and
draughts: as these may affect the
accuracy of the room thermostat
incorporated in the panel.
5) Do not attempt to open or remove the
panel, it requires no maintenance.
6) Do not press against the surface of the
liquidcrystal display:thiscoulddamage
the surface itself and cause viewing
problems.
7) To clean the display, simply wipe with a
dry cloth: any infiltrating liquid could
damage the liquid crystals.
WHAT IS THE REMOTE CONTROL
PANEL USED FOR?
The control panel offers the possibility of
controlling the operation of your boiler
without having to access it directly.
The control panel is normally installed in
the largest room of the house where it will
always be easy to make checks and
regulations.
HOW IT IS USED
The control panel has three operating
modes:
1) ROOM THERMOSTAT
Thecontrolpanelkeepsthetemperature
of the room constant on the basis of the
settings made by the user.
2) PROGRAMMABLE ROOM
THERMOSTAT
In this mode, you can programme 2
different temperatures settings for
certain periods of the day.

3) BOILER CONTROL
Inthismodethecontrol panel operates the
boilercontrols only.Itdoes notcontrol room
temperature or ON/OFF periods.
EXPLANATION OF TECHNICALTERMS
•Heating water: the water that flows
throughtheradiatorshavingbeenheated
in the boiler.
•Domestic hot water: thewaterthatflows
through the DHW fittings.
•Error code: a code that appears on the
display and signals any faults in the
boiler.
•Initial configuration: the configuration
set on the control panel when it is
switchedon for the first time or when it is
reset.
•Display: the liquid crystal screen on
which all the symbols corresponding to
the various functions are displayed.
•Antifreeze function: the function that
prevents a drop in temperature freezing
thewaterthatflowsin the pipes, causing
damage to the heating system. This
function is activated when the
environmental temperature drops below
6.6 °C.
•Reset: the operation that restores the
initial configuration of the control panel,
clearing all settings made by the user,
except for the system time.
•Summer operating mode: the mode in
whichthecontrolpanelistobesetwhen
the heating system does not have to be
in operation (e.g. spring, summer).
Theboilersuppliesdomestichotwateronly.
•Winter operating mode: the status in
whichthecontrolpanelistobesetwhen
theheating systemhastobe inoperation
(e.g. autumn, winter).
The boiler can supplies heating and
domestic hot water.
•Comfort level temperature: the
temperaturethatrepresentsidealheating
for the rooms.
•Room temperature: the temperature
measuredintheroomin which the panel
is installed.
•Outdoor temperature: the temperature
measured by the external sensor.
•Climatic curve (Linea & Compact
only): this is the relation between the
outdoor temperature and the calculate
flow outlet temperature, required when
an external sensor is fitted. The RC05
checks the temperature sensed at the
external sensor and calculates the
required flow outlet temperature based
on the curve that has been set on the
RC05 (see installation instructions). The
calculated flow outlet temperature
ensures optimum comfort and efficiency
is maintened. The curve is set by your
installer during the installation of the
RC05.
•Economy level temperature: the
temperature setting used during night-
setback or to maintain a minimum
temperature level in the property.
NOTE
• Theroom temperatureisdisplayedin the
range from -9.9 °C to 38 °C.
• The outdoor temperature is displayed in
the range from -20 °C to 18 °C.
• Temperatures outside these ranges are
indicated by means of three dashes “-
- -”.

Operation:
Whenevertheroomtemperaturemeasured
by the sensor is 0.4 °C less than the one
set by the user, the control panel makes a
request for heat to the boiler: during this
phase,thedisplayshowsthe indicator.
The boiler is turned off when the
temperature reaches the value set.
When the button is pressed, the
system returns to the ROOM THERMOSTAT
OFF operating mode (fig. 6).
If used as a timer thermostat, the control
panel will enable you to:
• setin advance,foreverydayoftheweek,
the desired temperature according to
specific time bands between which the
comfort level temperature (higher)
alternates with the economy level
temperature (lower).
This means that instead of having to set
thedesired temperaturelevelatalltimes,
the control panel is capable of following
the weekly schedule that best suits your
needs, making the boiler alternate
between comfort and economy settings.
Thecomfortlevel temperature should be
set when you want your ideal room
temperature. The economy level
temperature should be selected if you
want a certain temperature to be
maintained in the rooms as a minimum
threshold never to be exceeded (e.g.
when you are out or at night).
• set the heating and domestic hot water
temperature.
There are three operating modes:
• TIMER THERMOSTAT OFF
• TIMER THERMOSTAT SUMMER
• TIMERTHERMOSTATWINTER
