Operation
2.1 Functional description
The VarioWIN pellet central heating boiler and the Modular Energy System MES or the REG standard control
combine to form a perfect unit. The VarioWIN automatically fires when the control system signals a heating requi-
rement. Following „purging“ (safety function), ignition starts and the pellet metering auger switches on. The
burner pot is automatically filled with pellets. When flame formation has been detected (by the thermocontrol
sensor), the boiler enters flame stabilisation mode and then control mode (modulation mode) and keeps to the
specified boiler temperature setpoint (between 60 °C and 75 °C). The boiler enters burnout mode if the output
drops below the minimum nominal thermal output or no heating requirement is signalled by the control system.
The blower continues to run until the burner pot has cooled down. Therefore, do not switch off the electricity
supply to the device too soon.
2.1.1 VarioWIN Premium
Manual cleaning:
The heating surfaces are cleaned manually using the cleaning lever. The cleaning residues from the heating
surfaces and the combustion residues from the burner pot drop into the ash pan or ash pan space.
VarioWIN Premium-D with direct pellet feed and extraction port for mounting a year-round pellet con-
tainer
Direct pellet feed transports the pellets from a sheet steel tank or self-build pellet store via a rotary feeder to
the burner pot.
2.1.2 VarioWIN Exklusiv
Automatic cleaning:
Fully automatic heating surface cleaning:
A motor moves the heating surface cleaning system vertically and the heating surfaces remain clean.
Fully automated ash compactor:
The fully automated ash compactor uses a motor and pressure plate to compress the ash in the ash container.
This makes the emptying intervals up to 3 times longer.
VarioWIN Exklusiv-S with 41 kg pellet reserve supply container
The reserve supply container is loaded by hand.
VarioWIN Exklusiv-P with pneumatic pellet feed
The pellet feed uses a maintenance-free suction turbine to fill the VarioWIN reserve supply container fully auto-
matically with pellets from a pellet storage room or storage container. The pellet feed is switched on by the
lower fill level switch (proximity switch) in the reserve supply container or at the end of the enable time or the
beginning of the start time, and runs for as long as the reserve supply container is full. Filling is not started if
the boiler is in heating operation or the feed has been blocked by the control unit (outside the enable time, e.g.
at night). If the boiler is operating when filling is necessary, the boiler switches to burnout mode.
Switching between suction probes 1, 2 and 3 is fully automatic. The system changes to the next suction probe
after the reserve supply container has been filled a certain number of times. This means the storage room is
emptied as evenly as possible.
VarioWIN Exklusiv-D with direct pellet feed and extraction port for mounting a year-round pellet con-
tainer
Direct pellet feed transports the pellets from a sheet steel tank or self-build pellet store via a rotary feeder to
the burner pot.
