12 - START-UP AND OPERATION
ProCon Smartline wall-mounted condensation boiler designed for the
production of heating and domestic hot water (for H-HS models if connected
to an external water tank).
The control panel (Fig. 12.1) contains the main boiler control and manage-
ment functions.
12.1 - Switching on the appliance
Switch on the boiler as follows:
• set the digital clock as described in the paragraph 17.
• open the gas tap under the boiler by turning it anti-clockwise
• turn on the general switch of the system and then, after lowering the door,
turn the function selector to summer , winter or winter comfort
(only for S models) (Fig. 12.3) depending on the chosen operating mode.
After being powered, the boiler begins an automatic vent cycle lasting
approximately 2 minutes.
During this phase the two digits light up alternatively (fig. 12.16).
To interrupt the automatic vent cycle, pull out the handle A and press button B
(fig. 12.17).
For S models:
SUMMER (
): with the selector in this position, just the traditional domestic
hot water function is activated. The display indicates the temperature of the
domestic hot water (Fig. 12.4).
WINTER (
): with the selector in this position, the heating water and domestic
hot water functions are activated. The display indicates the delivery tempera-
ture of the heating water (Fig. 12.5) and that of the domestic hot water
depending on current demand (Fig. 12.4).
WINTER COMFORT (
): with the selector in this position, as well as the
traditional function of heating water and domestic hot water, the preheating
function is also activated which keeps the water in the domestic hot water
exchanger hot in order to reduce waiting times. The display indicates the
delivery temperature of the heating water (Fig.12.5) and that of the domestic
hot water depending on current demand (Fig. 12.4).
For H - HS models:
SUMMER (
, only with the external water tank connected): with the
selector in this position the traditional domestic hot water function provided
by the water tank is activated. The display indicates the delivery tempera-
ture (Fig. 12.4).
WINTER (
): with the selector in this position, the boiler produces hot water
for heating and, if connected to an external water tank, it provides water to it
to allow it to prepare domestic hot water. The display indicates the delivery
temperature of the heating water (Fig. 12.4 and Fig. 12.5).
Adjusting heating water temperature
To adjust the heating water temperature turn the knob marked
(fig. 12.6)
clockwise to increase and anticlockwise to decrease.
When turning the knob, the required temperature automatically appears on the
digital display.
Depending on the type of system, it is possible to pre-select the suitable
temperature range:
-
standard systems 40-80°C
- floor systems 20-45°C.
For further details, consult the “Boiler configuration” section.
Adjusting heating water temperature with an external probe connected
When an external probe is connected, the value of the delivery temperature is
automatically chosen by the system which rapidly adjusts ambient tempera-
ture to the changes in external temperature.
To increase or decrease the temperature with respect to the value automatically
calculated by the electronic board, turn the heating water selector (Fig. 12.6)
clockwise to increase and anticlockwise to decrease.
Adjustment settings range from comfort levels - 5 to + 5 which are indicated
on the digital display when the knob is turned.
Adjusting domestic hot water temperature
For S models: to adjust the domestic hot water temperature (baths, showers,
kitchen, etc.) turn the knob marked
(Fig. 12.7) clockwise to increase and
anticlockwise to decrease.
When turning the knob, the required temperature automatically appears on the
digital display. The domestic hot water adjustment ranges lies between 35 and
60 °C. When choosing the temperature, both for heating and domestic hot
water, the display shows the value being selected. About 4 seconds after the
selection has been made, the modification is memorised and the display returns
to the delivery or domestic hot water temperature read by the probe.
For H - HS models:
• CASE A heating only - adjustment inapplicable
• CASE B heating only + external water tank with thermostat - adjustment
inapplicable
• CASE C heating only + external water tank with probe - to adjust the tem-
perature of the domestic hot water in the water tank, turn the temperature
selector clockwise to increase and anticlockwise to decrease.
The adjustment range lies between 35 and 60°C.
When choosing the temperature, both for heating and domestic hot water, the
display shows the value being selected. About 4 seconds after the selection
has been made, the modification is memorised and the display returns to the
delivery temperature.
Working the boiler
If a programmable timer or ambient thermostat are mounted, these must be
switched on and adjusted to higher than ambient temperature in order to allow
the boiler to start.
The boiler remains on standby until the burner ignites as a result of a demand
for heat. The green indicator LED (A, Fig. 12.8), located on the left-hand side
of the panel, lights up to indicate the flame is present.
The boiler continues to work until the selected temperatures have been reached.
It then returns to “stand-by” while displaying delivery temperature.
In the event of a starting or operating fault, the boiler performs a “SAFETY
STOP”: the green indicator LED on the control panel goes out, a fault code
flashes on the display (Fig. 12.9) and a red indicator LED (B) lights up in the
event of a shutdown.
To identify the fault codes and reset the boiler, consult the “Indicator LEDs
and faults” section”.
Reset function
To reset the boiler, turned the function selector to
(Fig. 12.10), then move
it to the required position and check that the red indicator LED has gone out.
At this point, the boiler starts automatically if correct operating conditions
have been restored; when the burner ignites, the green indicator led lights up
and the digital display indicates the instantaneous operating temperature.
Simply turning the selector to does not reset the boiler.
If the boiler continues not to work, call in the local Technical Assistance Service.
In normal operating conditions, when the function selector is turned to
, the
digital display indicates “- -” (Fig. 12.11) unless the anti-freeze phase (AF) is in
progress or the combustion analysis function is activated (CO).
12.2 - Switching off
For short absences (weekends, brief journeys, etc.) turn the function selector
to
OFF/RESET.
The digital display will look like Fig. 12.11.
As the boiler remains powered with the gas tap open, it is protected by the
following systems:
• anti-freeze:
Heating
the function starts if the temperature measured by the delivery probe falls
below 6°C. In this phase, a heat demand is generated and the burner ignites
at minimum power. This is maintained until the temperature of the delivery
water reaches 35°C.
Domestic hot water (for H-HS only with connection to an external
water tank with probe)
the function starts if the temperature measured by the domestic hot water
probe (water tank probe for H-HS models) falls below 4°C. In this phase, a
heat demand is generated and the burner ignites at minimum power. This is
maintained until the temperature of the delivery water reaches 55°C for S -
35°C for HS.
During the anti-freeze phase, AF flashes on the display (Fig. 12.12).
• circulator anti-block: if the boiler remains inactive, the circulator performs
a 30-second operating cycle every 24 hours.
If the boiler is planned not to be used for a long period, proceed as follows:
• move the function selector to OFF-RESET
• turn the main system switch to “off”
• close the fuel and the heating and hot water taps (for S).
In this case, the anti-freeze and anti-block systems are disabled. Drain the
heating and hot water system (for S) if there is danger of freezing.
12.3 - Indicator LEDs and faults
Green indicator LED
Off = boiler on stand-by, no flame
On = burner on, the boiler works regularly.
Red indicator LED
Stop: just the fault code flashes on the digital display.
Block: the red indicator LED lights up and the fault code flashes on the digital
display.
The fault code is not displayed in the OFF/RESET (
) mode. To display it,
move the function selector to or . During combustion analysis and the
anti-freeze phase, instead, it is displayed.
To reset the boiler, turn the function selector to
(OFF/RESET) and then
move it to be required position: summer, winter or winter with preheating (for
S) (Fig. 12.3).
If the boiler still doesn’t work, call in the local Technical Service Centre.
For AL41 faults
If the pressure on the water gauge located on the control panel is less than
0.5 bar, proceed as follows:
• Turn the function selector to
(Fig. 12.10).
• Fill the system until the pressure indicated on the water gauge lies between
1 and 1.5 bar (Fig. 8.3).
