4.19 Temporary switch-off
-
Set the boiler to OFF .
While the electrical supply and the fuel supply remain active, the boiler is protected by the
systems:
-
heating anti-freeze
: this function is activated if the temperature measured by the flow sensor
drops below 5°C. A heat request is generated in this phase with the ignition of the burner at
minimum output, which is maintained until the outlet water temperature reaches 35° C;
-
domestic hot water anti-freeze (only if water tank connected)
: this function is
activated if the temperature measured by the water tank probe drops below 5°C. A heat
request is generated in this phase with the ignition of the burner at minimum output,
which is maintained until the outlet water temperature reaches 55° C.
b
The activation of the ANTI-FREEZE function is indicated by a scrolling message on
the foot of the REC10CH display.
-
circulator anti-locking
: the circulator activates every 24 hours of stoppage for 30
seconds.
4.20 Switching off for lengthy periods
The long term non use of the
FAMILY
boiler causes the following operations to be carried
out:
-
set the boiler to OFF
-
set the system’s main switch to “off”
-
close the fuel and water taps of the heating and domestic hot water system.
In this case, the anti-freeze and anti-blocking systems are deactivated. Drain the heating
and domestic water system if there is any risk of freezing.
4.21 System reset
b
This operation must be carried out only by professionally qualified personnel.
Whenever necessary, it is possible to restore the factory settings by carrying out a SYSTEM
RESET:

After a reset it is necessary to carry out a new configuration of the system; for details
about this procedure, see the following section.

System configuration
b
This operation must be carried out only by professionally qualified personnel.
When restarting after a replacement of the REC10CH rather than after a “SYSTEM
RESET”, the remote control an initial screen with the firmware revision. Pressing “

-
HW TANK: if the boiler manages a domestic hot water tank. Note: in this case the
specific type of domestic hot water request will be requested THERMOSTAT (case B) or
TEMPERATURE PROBE (case C)
-
if the water tank with probe is selected you are also asked whether to manage also the
solar heating system: answer No to this question.

Once the guided procedure has finished, the REC10CH will go to the initial screen.
Then proceed with the reprogramming of the boiler, carrying out the operations described
in the section “4.2 Programming the boiler”.
4.23
Boiler configuration
The BOILER menu allows you to change the hydraulic configuration without necessarily
having to go through a SYSTEM RESET operation.The HYDRAULIC CONF parameter can
assume values between 0 and 4 with the following meaning:
0 = only heating boiler
1 = instantaneous boiler with flowswitch
2 = instantaneous boiler with flowmeter
3 = only heating boiler with water tank with probe
4 = only heating boiler with water tank with thermostat
4.24 Replacing the REC10CH Master
b
The system configuration operations need to be carried out by professionally
qualified personnel of the Technical Assistance Centre.
When replacing the REC10CH MASTER, at the subsequent restart it displays an initial
screen with the firmware revision. Pressing “
ENTER
” starts a guided procedure for
configuring the system, see the section “Configuring the system”.
Follow the procedure and carry out the MAIN PCB type of configuration

4.25 Replacing the MAIN PCB board
The system configuration operations need to be carried out by professionally qualified
personnel of the Technical Assistance Centre. The systems continually carries out a
consistency control between the configuration data saved on the MAIN PCB electronic board
and that saved in the REC; therefore, when replacing the MAIN PCB electronic board, it might
happen that the system detects an inconsistency between the data saved on the MAIN PCB
and that in the REC. In this case, the latter will ask the user which of the two configurations is to
be considered valid; selecting to recuperate the configuration from the REC itself it is possible
to avoid reconfiguring the machine:
-
select REC10CH.

4.26 Combustion Control Parameters
Even if the parameters regarding the new ACC combustion control system (active
combustion control) are preset in the factory, it might be necessary to programme them, this
is in the case where both electronic boards (MAIN PCB and REC10CH MASTER) need to
be replaced at the same time.
