ENGLISH QUADRA GREEN 25 R.S.I.
The boiler continues to operate until the temperatures set on the boiler are
reached, or the heat request is met; after which it goes back on standby.
If the red LED indicator near the sy mbol (fig. 33) on the control panel
lights up, this means the boiler is in temporary shutdown status (see chap-
ter “Light signals and faults”).
The digital monitor indicates the fault code detected.
Automatic Temperature Control System function (S.A.R.A.) fig. 34
Setting the heating water temperature selector to the area marked “AUTO”
(temperature range 55 to 65°C), activates the automatic temperature con-
trol system (frequency 0.1 sec. on; then 0.1 sec. off; for 0.5 seconds): ac-
cording to the temperature set on the room thermostat and the time taken
to reach it, the boiler varies automatically the heating water temperature
reducing the operating time, allowing greater ease of operation and energy
saving. On the control panel, the green LED flashes ON for 0.5 seconds,
OFF for 3.5 seconds.
Reset function
To restore operation, set the function selector to (fig. 31), wait 5-6 sec -
onds then set the function selector to the required position, checking that
the red indicator light is OFF.
At this point the boiler will automatically start and the red lamp switches on
in green.
NOTE: If the attempt to reset the appliance does not activate operation,
contact the Technical Assistance Service.
4.2 Switching off
Temporary switch-off
In case of absence for short periods of time, set the mode selector (fig.
31) to (OFF).
In this way (leaving the electricity and fuel supplies enabled), the boiler is
protected by the following systems:
Anti-frost device: when the temperature of the water in the boiler falls
below 5°C, the circulator and, if necessary, the burner are activated at mini-
mum output levels to bring the water temperature back to the values for
safety (35°C). During the anti-frost cycle, the symbol (fig. 35) appears
on the digital monitor.
Circulator anti-blocking function: an operation cycle is activated every
24 hours.
DHW Antifreeze (only when connected to an external storage tank with
probe): the function is activated if the temperature measured by the storage
tank probe drops below 5° C. A heat request is generated in this phase with
the ignition of the burner at minimum power, which is maintained until the
water temperature reaches 55° C. During the anti-frost cycle, the symbol
(fig. 35) appears on the digital monitor.
Switching off for long periods
In case of absence for long periods of time, set the mode selector (fig. 31) to
(OFF). Turn the main system switch OFF. Close the fuel and water taps
of the heating and domestic hot water system. In this case, anti-frost device
is deactivated: drain the systems, in case of risk of frost.
