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 readyto

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

è Note:

The connectors are coded to make certain they cannot be mixed up.

1. Making the connections

13/184

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 cutout without applying any force

è 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 position of the fixing levers.

2373Z07

Tighten the 2 screws on the front of the controller

è Note:

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.

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 sameduct

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

1 Press one of the line selection buttons.

This will take you to the programming mode.

2 Press 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.

3 Press 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 / divertingvalve (Q3/ Y3) is

activated

Test step 5 Heating circuit 1 / boiler pump (Q2) is activated

Test step 6 Mixingvalve HC1OPEN (Y1) isactivated

Test step 7 Mixing valve HC1 CLOSED (Y2) is activated

Test step 8 Heating circuit pump HC2 (Q6) is activated

Test step 9 Mixingvalve HC2OPEN (Y5) isactivated

Test step 10 Mixing valve HC2 CLOSED (Y6) is activated

4 By 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.
