3. HOW TO...
3.1 HOW TO TOP-UP THE SYSTEM
PRESSURE
The system pressure must be checked periodically to ensure
the correct operation of the boiler. The system pressure is
shown at the top of the LCD display or can be read on the
gauge located on the underside of the appliance. When the
boiler is at room temperature, the system pressure should be
approximately 1.0 bar.
If the pressure requires ‘topping-up’ use the following instructions
as a guide.
- Locate the filling valve connections (usually beneath the
boiler, see fig. 1).
- Attach the filling loop to both connections.
- Open the filling valve slowly until you hear water entering the
system.
- Close the filling valve when the pressure gauge (on the boiler)
reads between 1 and 1.5 BAR.
- Remove the filling loop from the connections.
3.2 HOW TO RESET THE APPLIANCE
Reset function
In order to reset the boiler’s operation in the event of a fault,
it is necessary to access the fault description screen. If the
lockout is of a non-volatile type that requires a reset procedure,
this will be indicated on the screen, and can be carried out by
pressing the
“ok”
button on the REC10H.

PRESS OK RESET
At this point, if the correct operating conditions have been
restored, the boiler will restart automatically.
If the attempts to reset the fault do not restore the boiler’s
functionality, please contact your local Customer Support
Service.
Up to a maximum of 3 reset attempts can be made using
the REC10CH. In case of all the attempts are exhausted
the definitive fault E099 occurs on the display. After these
operations the machine must be disconnected from the power
supply to reset the number of attempts available.

If the attempts to reset the fault do not restore the
boiler’s functionality, please contact your local Customer
Support Service.

WINTER
Provided that the electrical and gas supplies remain switched
ON to the appliance, the following frost-protection functions
will remain active in order to protect the appliance:
-
heating frost-protection:
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;
-
DHW frost-protection:
the function starts if the temperature
measured by the DHW sensor falls 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 FROST-PROTECTION function
is indicated by a scrolling message at the base of the
REC10H display.
-
pump anti-blocking:
the circulating pump is energised
for a 30-second period if it remains inactive for more than
24-hours.
3.4 HOW TO SHUT DOWN THE SYSTEM FOR
LONG PERIODS
If the boiler will not be in used for a prolonged period of time,
the following operations must be carried out:
- switch the boiler to OFF
- isolate the appliance from the gas and electricity supplies.
In this case, the frost-protection and anti-blocking systems
are deactivated. Drain both the heating and domestic water
systems to avoid any risk of freezing.
