1 Summary
1.1 Brief description
ALBATROS™- RVA47.320 (B-series) is designed for use as a single-boiler controller or
cascade controller with up to 12 heat sources.
It is designed for integration in heat generating equipment / plants with
• a modulating gas burner
• a Boiler Management Unit (BMU)
• d.h.w. heating with charging pump (via RVA47) or changeover valve
(via BMU)
• a primary or heating circuit pump
Heating circuit control uses weather compensation while d.h.w. heating operates
depending on the storage tank temperature and the time program.
When employed in an interconnected system along with the ALBATROS™ controller
RVA43.222 (C-series), it is possible to operate mixed cascades (modulating / multistage) with up to 15 heat sources.
When used in connection with gas-fired heating boilers, the availability of a BMU is
mandatory. Siemens offers different types of BMUs:
- Boiler Mangement Unit LMU5/6x
It is also possible to use BMUs of other manufacture if appropriately equipped. If you
intend to use a non-Siemens burner control in connection with the RVA47.230, please
contact your nearest Siemens representative.
The range of products comprises several units that complement one another in terms of
application and scope of functions. The controllers have communication capability and
can be combined to form heating systems that include up to 40 controllers.
For more detailed information about the generation of LPB systems, refer to "Local
Process Bus (LPB), Basic Documentation, System Engineering”, document no.

2 Handling
2.1 Installation
2.1.1 Mounting location
• Boiler control panel
• In the control panel front
2.1.2 Regulations for installation
• A clearance of at least 10 mm must be provided on all sides of the controller,
enabling the unit to emit the amount of heat produced during its operation. The
space should not be accessible and no objects should be placed there.
• The controller is designed for mounting in a boiler control panel. Power to the
controller may be supplied only after it is completely fitted in the cutout. If this is not
observed, there is a risk of electric shock near the terminals and through the
cooling slots.
• If the controller shall be mounted directly on the wall, a housing must be used to
provide protection against electric shock hazard. The housing must have a
sufficient number of cooling slots at the bottom and the top, allowing the controller
to emit the heat it produces.
• The controller has been designed based on the guidelines of safety class 2 and
must therefore be mounted in compliance with these regulations.
• The controller may not be exposed to dripping water.
• Permissible ambient temperature: 0...50 °C
2.1.3 Mounting procedure
Description Diagram
• Turn off power supply
• Pull the prefabricated cables
through the cut-out
• Plug the connectors into the
respective sockets at the rear of the
controller
Note:
The connectors are coded to make
certain they cannot be mixed up.
2379Z11
1. step
14/166
Siemens Building Technologies Basic Documentation RVA47.320 CE1P2379E
HVAC Products Handling 15.07.2002
• Check to ensure the fixing levers
are turned inward
• Check to make certain there is
sufficient space between the front
panel and the fixing levers
2379Z12
• Slide the unit into the panel cut-out
without applying any force
Note:
Do not use any tools when inserting
the unit into the cut-out. If it does not
fit, check the size of the cut-out and
the housing.
2379Z13
• Secure the fixing levers by
tightening the two screws on the
front of the controller.
Note:
Tighten the screws only slightly .
When tightening the screws, the
fixing levers automatically assume
their correct positions.

Siemens Building Technologies Basic Documentation RVA47.320 CE1P2379E
HVAC Products Handling 15.07.2002
2.1.4 Required cut-out
The controller’s mounting dimensions are 91 x 91 mm.
Due to the dimensions of the front, however, the standard spacing is 96 mm.
The mechanical mounting facility allows the controller to be fitted in front panels having
a thickness of 2 to 10 mm.
The mechanical mounting facility makes
it possible to arrange several controllers
in a row in one cut-out. In that case, it is
merely necessary to have a wider panel
cutout.
2379Z15
2.1.5 Orientation
To avoid overtemperatures inside the
controller, the inclination may be no
more than 30° and there must be a
clearance of at least 10 mm on all sides
of the unit.
This allows the controller to emit the
heat generated during operation.

2.2 Electrical installation
2.2.1 Regulations for installation
• The connections for mains and low voltage are separated
• The wiring must be made in compliance with the requirements of safety class II.
This means that sensor and mains cables may not be run in the same duct
2.2.2 Wiring
When using prefabricated cables with connectors, the electrical installation is very
straightforward, owing to the coding.

2.3 Commissioning
To commission the controller:
1. Make certain that mounting and electrical installation are in compliance with the
relevant requirements.
2. Make all plant-specific settings as described in section "Parameter settings".
3. Reset the attenuated outside temperature (operating line 19).
4. Make the functional checks.
2.3.1 Functional checks
To facilitate commissioning and fault tracing, the controller allows output and input tests
to be made. With these tests, the controller’s inputs and outputs can be checked.
Buttons Explanation Line
