Albatros RVA63.242 is an equithermal
control unit designed for serial connection
to the source of heat with:
• one or two-stage burner, 1BMU
• hot water supply pump or hot water he-
ating bypass valve
• one or two heating circuits with a three-
-point blender drive and circulation
pump, or with a circulation pump only
All the above equithermal control units
can be mutually combined, allowing more
complex heating systems to be built. More
detailed documentation is supplied with
the equithermal control units, or can be
viewed on website www.siemens.cz.
Connecting room control unit
The boiler has a special terminal box for
connecting a room control unit, located
underneath the control panel. The zero-
potential contact control unit is connected
by an electrical wire. If a unit requiring
230 V power supply is used (bimetal, with
heating resistor), it has to be connected
to the terminal box by a three-core cable.
The boiler’s manufacturer supplies suit-
able room control units as an option.

Control panel and signallization
Locations of the boiler’s control and signalling elements are illustrated in the picture of the
boiler’s control panel (Fig. X).
The boiler has two control panels:
– Main control panel, with basic control elements for the user
–
Service control panel (located under the front cover), used for service settings.
Description of control elements
Main switch
– used to cut off power supply
to the boiler.
“Flame out” control light
– a red light sig-
nalling a fault caused by the flame going
out. The fault may be caused by gas sup-
ply interruption during start up or while the
boiler is running.
“Boiler overheated” control light
– and or-
ange light signalling a fault triggered by:
– the combustion fumes thermostat af-
ter drop or loss of chimney effect,
– the emergency thermostat when the
heating water temperature exceeds
105°C (98°C in open systems).
Thermometer, pressure gauge
– show
temperature and pressure, respectively, of
the heating water in the boiler.
Boiler output switch (two flames – one
flame)
– used to switch between two op-
eration stages (LOW/HIGH).
Pump thermostat
– used to protect the
cast iron body of the boiler against con-
densation. After igniting the burner, the
boiler pump runs until the temperature
exceeds 60°C (factory setting). This tem-
perature setting may be changed by au-
thorised service only.
Heating operation controls
– used to set
the heating water temperature.
Important:
The selected temperature
must be always higher than the tempera-
ture set on the pump thermostat. If not, the
pump will stay permanently switched off.
Emergency thermostat
– used to protect
the boiler against overheating. If over-
heated, the thermostat will shut the boiler
down. The boiler can be restarted after
the heating water in the boiler has cooled
off by pressing an unlocking button (11),
which is sometimes located under a plas-
tic plug.
Combustion fumes thermostat
– used to
shut the boiler down when the chimney ef-
fect has been reduced or lost. The boiler
can be unlocked only after the combus-
tion fumes thermostat has cooled off, by
pressing an unlocking button (12).
Important:
The boiler must never be run
with the above described safety elements
(combustion fumes and emergency ther-
mostat) disabled or replaced by devises
other than those specified by the manu-
facturer! Under no circumstances may the
user manipulate with these elements.
RESET button
– by pressing this button,
the fault signalled by the “Flame out” red
control light can be fixed. If the fault is sig-
nalled repeatedly, call authorised service.
For fault statuses triggered by the com-
bustion fumes of emergency thermostat,
using the RESET button is ineffective.
In such cases it is necessary to call au-
thorised service, which will diagnose the
problem and after repairing the fault put
the boiler back into operation.
Power mains fuse
– protects the boiler’s
electrical wiring against overloading and
short circuit.
