SWITCH ON AND OFF
6.3.1
Switching on
1. Open the gas tap (only for heating mode operation).
2. Power up the gas-fired convector by inserting the
three-pole plug.
3. The display will show the time, the word OFF and the
red LED E will light up.
4. To power on the gas-fired convector, press button A
for at least 2 seconds: the following information
will appear on the display:
▶
the time - 12.00- and the day of the week - 1 –
▶
the preset ambient temperature - 4 -
▶
the radiator icon
at the bottom left informs the us-
er that the gas-fired convector is in heating mode
5. Set the temperature level to a value between 1 and 6
as follows:
▶
Turn knob D clockwise to increase or counterclockwise
to reduce the required temperature level: the level val-
ue will start flashing.
▶
Press the knob to confirm the newly selected value
and return to normal display mode.
6. If the room temperature is below the set temperature
level, the radiator icon will start flashing and after a
few seconds the burner will ignite.
7. The presence of the flame is signalled by the flame
icon
, which consists of 2 levels: small flame indi-
cates that the gas-fired convector is in modulation,
while the double flame indicates that the gas-fired
convector is at maximum heat output.
8. The room fan will start automatically when the heat
exchanger is hot. The ventilation speed will be propor-
tional to the heat output of the burner (maximum or
modulated).
9. In the event of a failure to switch on, the control board
locks out the gas-fired convector: the fault is highlight-
ed by the alternating flashing of the display backlight,
the switching on of the red LED E and of the alarm icon
and the message "r001 Err" on the display.
To reset the error, press the reset button C
. The
disappearance of the error code on the display con-
firms that the reset command has been accepted.
After 3 consecutive flame lock-outs "r001 Err", the
error "r091 Err" will be displayed. The gas-fired
convector can be reset by power cycling it or by
waiting at least 1 hour after the most recent flame
lock-out.
10. Select the desired operating mode among those de-
scribed in the relevant paragraph (see Paragraph
6.4
6.3.2
Switching off
You can turn off the gas-fired convector in either of the
following two ways:
▶
press button A
for at least 2 seconds: the word OFF
will appear on the display and the red LED E will light
up.
▶
lower the required temperature level by turning the
knob counter-clockwise until the value 1.0 is achieved
(corresponding to a room temperature of approx. 5
°C).
The gas-fired convector can also be programmed to oper-
ate with different temperature levels (Comfort, Economy,
and antifreeze). For programming instructions, refer to
Paragraph 6.5.2

OPERATING MODE SELECTION
The different operating modes of the Calorio M gas-fired
convector are described below.
6.4.1
Manual operation
1. Press manual operation button B
: the hand icon
appears on the display.
2. During heating operation, the radiator icon
is
shown on the display (fixed if the burner is lit or if the
gas-fired convector is in stand-by, flashing if the gas-
fired convector is being switched on).
3. In this operating mode, the manually set room tem-
perature level (shown on the display) will be main-
tained permanently; to change the room temperature
level, use the knob (rotate - press to confirm) until the
desired value is set.
4. In summer mode (ventilation) the fan icon
is
shown on the display and air circulation will be con-
stantly ensured.
6.4.2
Automatic operation
1. Press automatic operation button B
: the clock icon
appears on the display.
2. The gas-fired convector will operate according to
the programmed time schedules (see Paragraph
p. 25), in particular:
Heating operation: during operating periods (on),
the set comfort temperature will be maintained
(sun icon
lit ), while during off periods, the
economy temperature will be maintained (moon
icon
lit); if the economy temperature is set to
off, the heating will be turned off (the antifreeze
function will not work, even if enabled).
Summer mode (ventilation): air circulation is only
guaranteed during on periods (fan icon
lit).
6.4.3
Temporary manual operation
1. If during automatic operation (Paragraph 6.4.2 p. 24)
the room temperature is changed (by turning and
pressing the knob), operation switches from automat-
ic to temporary manual.
2. In this operating mode, the manually set room tem-
perature (shown on the display) will be maintained
until the next automatic change of the time program
or until the button B
is pressed.
3. The display shows the fixed auto icon
and the
