1. Start-up when the boiler
temperature is below 78°C, the
cartridge has not opened, the
beam for self-circulation is tight
against the accumulator tank due
to pump pressure.
2. Operational phase when
the boiler temperature exceeds
78 °C, the cartridge opens
and mixes cold water from the
accumulator tank. Boiler water
return temp is normally about
70°C. At 90°C from the boiler,
the Laddomat normally gives
66°C back to the boiler.
3. Final phase When the
accumulator tank is fully charged,
hot water will enter on the cold
side of the Laddomat. Then the
plunger opens fully toward the
accumulator tank and closes the
pipe toward the top of the boiler.
All flow now goes to the
accumulator tank. This feature
is important for the accumulator
tank to charge fully.
4. Self-circulation
event of loss of electricity or
failure of the circulation pump,
the check valve is opened for
self-circulation. This will normally
prevent
boiling
unless
accumulators are fully charged or
the piping presents an obstacle
for circulation.
