2 Handling
2.1 Installation
2.1.1 Regulations for installation
.
•Air circulation around the controller must be ensured, allowing the unit to emit the
heat produced by it.
A clearance of at least 10 mm must be provided for the controller's cooling slots
which are situated a the top and bottom of the housing.
The space should not be accessible and no objects should be placed there.
If the controller is enclosed in another closed (insulating) casing, a clearance of up to
100 mm must be observed on all sides
•The controller is designed conforming to the directives for safety class II mounted in
compliance with these regulations
•Power to the controller may be supplied only after it is completely fitted in the cut-out.
If this is not observed, there is a risk of electric shock hazard near the terminals and
through the cooling slots
•The controller may not be exposed to dripping water
•Permissible ambient temperature when mounted and when ready to
operate: 0...50 °C
2.1.2 Mounting location
•In the boiler front
•In the control panel front
2.1.3 Mounting procedure
•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
èNote:
The connectors are coded to make
certain they cannot be mixed up.

Siemens Building Technologies Basic Dokumentation RVA63.280, RVA53.280 CE1P2374E
Landis & Staefa Division 19.04.2001
•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
2373Z06
•Slide the controller into the panel cut-
out without applying any force
èNote:
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 position of the fixing levers.
2373Z07
Tighten the 2 screws on the front of the
controller
èNote:
Tighten the screws only slightly,
applying a torque of maximum
20 Ncm.
When tightening the screws, the
fixing levers automatically assume
their correct positions.

2.1.4 Required cut-out
The controller's mounting dimensions are 91 x 137 mm
Due to the dimensions of the front, however, the standard spacing is 144 mm
The controller can be fitted in front panels of different thicknesses
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.
Also refer to "Dimensions" in Index.

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 above and
below the cooling slots.
This allows the controller to emit the
heat generated during operation.

2.2 Electrical installation
2.2.1 Regulations for installation
•Prior to installing the controller, the power supply must be turned off
•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 coding.

2.3 Commissioning
To commission the controller:
•Make certain that mounting and electrical installation are in compliance with the
relevant requirements
•Make all plant-specific settings as described in section "Parameter settings"
•Reset the attenuated outside temperature
•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
1Press one of the line selection buttons.
This will take you to the programming mode.
2Press both line selection buttons for at least 3
seconds.
This will take you to the programming mode “Heating
engineer” and, at the same time, to the output test.
3Press the + or - button repeatedly, which will take you
one test step further:
Test step 0 All outputs are switched according to normal control
operation
Test step 1 All outputs are deactivated
Test step 2 Burner stage 1 (K4) is activated
Test step 3 Burner stages 1 and 2 (K4 + K5) are activated
Test step 4 D.h.w. charging pump / diverting valve (Q3 / Y3) is
activated
Test step 5 Heating circuit 1 / boiler pump (Q2) is activated
Test step 6 Mixing valve HC1 OPEN (Y1) is activated
Test step 7 Mixing valve HC1 CLOSED (Y2) is activated
Test step 8 Heating circuit pump HC2 (Q6) is activated
Test step 9 Mixing valve HC2 OPEN (Y5) is activated
Test step 10 Mixing valve HC2 CLOSED (Y6) is activated
4By pressing any of the operating mode or line
selection buttons, you leave the programming mode
and thus the output test.
Note:
If no button is pressed for about 8 minutes, the
controller will automatically return to the operating
mode selected last.
