1.2 Operating the boiler
1.2.1 Switching on
- Open the gas stop cock.
- Turn power mains switch to ON.
- Set boiler power switch no. 17 (pic.1) to ON (the switch lights
up)
- Choose boiler mode through knob no. 11, no. 12 and no. 13 and
the programmable programmer no. 15 (please, refer to 1.2.2.3
and 1.2.2.4 paragraph).
- Adjust room temperature through room thermostat (when available).
- When CH is required, no. 10 light comes on (pic. 1).
- When the burner is on, no. 3 light comes on (the light comes on
when the flame detection electronics are powered, therefore even
if the light is on, flame might still not be present).
IMPORTANT
the production and maintenance of domestic hot water always
has priority over the central heating function. When there is no
demand for heating the boiler is kept at a temperature of 70 °C
to avoid waitings when requiring DHW.
1.2.2 Operation
SELECTOR (11, pic. 1)
The selector (3 positions) is for setting the operation mode of the
unit:
WINTER: all of the functions are enabled (HEATING, MAIN-
TENANCE, DOMESTIC WATER, ANTI-FREEZE, PUMP ANTI-
BLOCKAGE).
SUMMER: the HEATING function is disabled (the functions
MAINTENANCE, DOMESTIC WATER, ANTI-FREEZE, PUMP ANTI-
BLOCKAGE are enabled).
ANTIFREEZE: the functions ANTI-FREEZE and PUMP ANTI-
BLOCKAGE are enabled.
HEATING
The control card regulates the heating temperature from a value of
50°C to 82°C according to the value set by the operator with the
regulator 13 (pic. 1).
The heating function is requested when the contact of a room ther-
mostat (optional) and the contact of a programming clock (optio-
nal) are closed; such request terminates when one of the contacts
opens or if there is a demand for hot water.
At the end of the heating the heating pump carries out a post-cir-
culation of 180 seconds and then it turns off.
The function HEATING is not enabled when the selector is set to
SUMMER and ANTI-FREEZE.
MAINTENANCE
In the absence of demand for heating and hot water, the control
card will regulate the temperature of the primary at a fixed value
of 50°C, in order to speed the response time should there be a
demand for domestic hot water.
The MAINTENANCE function is not enabled when the selector is in
the ANTI-FREEZE position.
DOMESTIC HOT WATER
The domestic hot water function starts when the contact of the
flow sensor closes and terminates when the same contact of the
flow sensor opens.
The control card regulates the temperature of the domestic hot
water from 35°C to 57°C depending on the setting made by the
operator with the regulator 12 (pic. 1).
The DOMESTIC HOT WATER function is disabled when the se-
lector is in the ANTI-FREEZE position.
ANTI-FREEZE
The anti-freeze function is enabled in all of the positions of the
selector:
- when the supply temperature falls below 5°C, the control card
starts up the burner and the heating pump until a supply tempera-
ture of 50°C is reached, or, if the supply temperature of 50°C is not
reached, until reaching a functioning time of 15 minutes;
- when the temperature of the domestic hot water falls below 5°C,
the control card starts the burner and the water pump until the
temperature of 8°C of the water has been reached or, if 8°C are not
reached, until the functioning time of 15 minutes is reached. The
supply temperature in this phase is brought to 50°C.
HEAT ABSORPTION
When the supply temperature exceeds 90°C the pumps come on
to absorb heat. In particular:
- in the SUMMER position the hot water pump runs until the sup-
ply temperature does not fall below 85°C;
- in the WINTER and ANTI-FREEZE position the heating pump will
run until the supply temperature does not fall below 85°C.
PUMP ANTI-BLOCKAGE
Every 24 hours the pumps (heating and domestic hot water) are
activated for 180 seconds to avoid blockage.
ZONE HEATING
Should there be the necessity to heat 2 or 3 zones indepen-
dently at a high temperature, it is possible to connect a zone
card to the boiler (optional) + an interface Open Therm (optio-
nal). It is also possible to manage 1 zone at a high temperature
+ 1 zone at a low temperature (with fluid temperature); in this
case, besides these two cards, it is necessary to utilise the ex-
ternal sensors (optional) to be connected to the zone cards.
