DESCRIPTION
FUTURIA 24 PLUS MB W TOP
Perfectly air-tight with respect to its surroundings, this unit is suitable for heating water to temperatures
below boiling point at atmospheric pressure. Fully automatic, the FUTURIA PLUS boiler is governed by
an electronic microprocessor-operated control box.
Continuous power modulation is effected both on the heating circuit and the hot water circuit, by
means of an electronic board controlling fan r.p.m.
Combustion analysis (indispensable at the first ignition) allows adjustment of gas delivery flow-rate so
that the right air/gas mix is always obtained. Each variation in fan r.p.m. (and the resulting air-flow)
corresponds to a variation in the gas delivery rate.
This operation ensures a constant air-gas ratio whatever the flame intensity, thus guaranteeing maximum
combustion efficiency and hygiene under all working conditions.
The electronic board also provides:
-
3-way valve and circulation pump efficiency test; this prevents the lock-out that might otherwise
occur when the boiler remains idle for a prolonged period (the valve and pump are operated for a
set time every 24 hours).
-
Anti-freeze device:
when the heating water temperature falls below 10
°
C the circulation pump
comes on. If temperature continues to fall the burner will ignite at 3
°
C,
burning at minimum. It will be switched off when the water is reheated to
10
°
C.
This is why the boiler must be left connected to the power supply
even when it is not in use.
-
Board memory:
The control box microprocessor will memorise and signal any anomalies.
This information is stored on the memory even when the power is off and
can be recalled by connecting up to a PC.
-
“Sliding temperature”
mode with external temperature compensation.
