Mynute Green R.S.I. E:
Summer mode (only with the external water tank connected):
turning the selector to the symbol summer
function of only domestic hot water is activated and the boiler
supplies water at the temperature set on the external storage tank.
If there is a domestic hot water request the digital display shows
the hot water system temperature, the icon to indicate the hot water
supply and the flame icon.
Winter mode: by turning the mode selector within the area marked
"+" and "-" (fig. 32), the boiler provides hot water for heating and
- if connected to an external storage tank - domestic hot water. If
there is a heat request, the boiler switches on and the digital monitor
indicates the heating water temperature, the icon to indicate heating
and the flame icon (fig. 27). If there is a domestic hot water request,
the boiler switches on and the digital display shows the hot water
system temperature, the icon to indicate the hot water supply and the
flame icon (fig. 28).
- Adjust the room thermostat to the required temperature (~20°C).
Adjustment of the heating water temperature
To adjust the heating water temperature, turn the knob with symbol
(fig. 26) within the area marked "+" and "-".
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 "4.5 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 temperature 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. 26) 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.
Mynute Green C.S.I. E:
Adjustment of domestic hot water temperature
To adjust domestic water temperature (bathrooms, showers, kitchen,
etc.), turn the knob with symbol
"+" and "-". The boiler is standby status until, after a heat request, the
burner switches on and the digital display shows the hot water system
temperature, the icon to indicate the hot water supply and the flame
icon. The boiler will be in function until the adjusted temperature is
reached, afterwards it will be in "standby" again.

Environment Automatic Adjustment System Function (S.A.R.A.)
(A - fig. 33)
By setting the heating water temperature selector to the area marked by
AUTO - temperature value from 55 to 65°C - the S.A.R.A. self-adjusting
system is activated: the boiler varies the delivery temperature according
to the closing signal of the room thermostat. When the temperature set
with the heating water temperature selector is reached, a 20 minutes
count begins. If during this period the room thermostat still requests
heat, the value of the set temperature automatically increases by 5 °C.
When the new value is reached, other 20 minutes count begins.
If during this period the room thermostat still requests heat, the value of
the set temperature automatically increases by 5 °C.
This new temperature value is the result of the temperature set manually
with the heating water temperature selector and the increase of +10 °C
of the S.A.R.A function. After the second cycle the temperature value
should be kept at the set value +10°C until the request of the room
thermostat is satisfied.

Switch-off
Temporary switching off
In case of absence for short periods of time, set the mode selector (3
- fig. 24) 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 minimum output levels to bring the water temperature
back to the values for safety (35°C). During the anti-frost cycle, the
symbol
appears on the digital monitor (fig. 34).
- 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
the digital monitor (fig. 34).
Long period switching off
In case of absence for long periods of time, set the mode selector (3 -
fig. 24) to
(OFF). Then, close the gas tap present on the system. In
this case, anti-frost device is deactivated: empty the systems, in case
of risk of frost.
