TO USE THE REMOTE CONTROL PANEL CORRECTLY, CAREFULLY READ
THE CONTENTS OF THIS DOCUMENT.

WARNINGS:

1) The remote control must be installed where it can
be easily accessed for ambient temperature control
(generally in the living room).

2) To optimize legibility of the display, the control
panel must be positioned 5 feet from the floor, as
required by regulations.

3) The control panel is powered by low voltage
directly from the boiler.

4) The control panel must be kept away from heat
sources or drafts, as these can compromise the
accuracy of the ambient probe incorporated in the
panel.

5) Never open the panel, as it is maintenance-free.

6) Never press on the glass of the liquid crystal
display, as this may damage the glass and impair
viewing.

7) Only use a dry cloth to clean the display, as any
infiltration of liquids may damage the liquid crystals.

GLOSSARY OF TECHNICAL TERMS

• Heating water: This is the water which flows in the
comfort heat radiators after having been heated by
the boiler.

• Domestic hot water: This is the potable water
which flows to the fixtures in the home.

• Fault code: This is a code which appears on the
display to report any boiler or control panel opera­tional problems.

• Initial configuration: This is the configuration of
the control panel after initial start-up or resetting.

• Display: This is the liquid crystal screen showing
all the symbols corresponding to the various func­tions.

• Freeze protection function: This function pre­vents low temperatures from freezing the water
flowing inside the pipes and damaging the heating
system. This function activates when the ambient
temperature falls below 40°F (5°C).

GENERAL INFORMATION

WHAT DOES THE REMOTE CONTROL
PANEL DO?

The remote control panel allows you to control the
temperature in your home and the operation of your
boiler without having to access the boiler directly. For
reasons of space, in fact, your boiler may be installed
outside the living space (e.g.: basements, garages,
external areas, etc.). The control panel, on the other
hand, is generally installed in the largest room of the
home, where control and adjustment operations can
be performed with ease.

OPERATING METHOD

The control panel allows more refined home heating
management, as you can decide how and when to
start the boiler. It also allows you to set the domestic
hot water temperature without having to access the
boiler panel. This manual sets out to explain each of
these operating methods and their connected func­tions.

• Control panel reset: This operation is performed
to reset the initial configuration of the control panel
by deleting any user program apart from the sys­tem clock.

• Summer mode: Set the control panel to this mode
when the heating system is not required (e.g.:
spring, summer). The boiler only delivers domestic
hot water (when piped to domestic hot water).

• Automatic heating and continuous heating
mode: Set the control panel to this mode when
heating is required (e.g.: autumn, winter). The boil­er delivers both domestic hot water and heating
water.

• Comfort temperature: This temperature optimizes
heating in the home.

• Setback temperature: This temperature is used
when the home is uninhabited, or during the night.

• Ambient temperature: This is the temperature
measured in the room in which the remote control
panel is installed.

3

• Outdoor temperature: This is the temperature
easured outside the house by the external sensor

m
(if installed) connected to the boiler.

• Outdoor reset curve: This is the relationship

between the external temperature and the tempera­ture of the heating water. If the outdoor probe is
installed with the boiler, the temperature of the
heating water is automatically adjusted according
to the changes in outdoor temperature in order to
maintain a constant temperature in the home. The
outdoor reset curve is chosen by the installer
according to the geographical location and system

NOTE:

• The ambient temperature display ranges from
32°F to 210°F (0°C to 99°C).

• The outdoor temperature display ranges from

-38°F to 102°F (-39°C to 39°C).

• Temperatures outside these ranges are displayed
with three dashes “---”.

• Temperatures below 100° (°F or °C) will be dis­played in tenths of a degree (XX.X).

• Temperatures of 100° or higher (°F) will be dis­played in whole degrees (XXX°F)
