2 Safety notes

2.1 Product liability

• The products may only be used in building services plant and applications as

described in this document

• When using the products, all requirements specified in chapters "Handling" and

"Technical data" must be satisfied

• Local regulations (for installation, etc.) must be complied with

• Do not open the units. If not observed, warranty by Siemens becomes void

11/100

Siemens Schweiz AG User Manual CE1U2353en HVAC Products Mounting and installation 22. November 2006

3 Mounting and installation

3.1 Regulations

• Prior to installing the controller, power 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 must not be run in the same duct

3.2 Basic units RVS…

Planning

• Air circulation around the unit 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 unit's cooling slots at the top and bottom of the housing. That space should not be accessible and no objects should be placed there. If the controller is enclosed in another (insulating) casing, a clearance of up to 100 mm must be observed around the cooling slots

• The controller is designed conforming to the directives for safety class II devices mounted in compliance with these regulations

• Power to the controller may only be supplied when completely fitted. 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

• Power cables must be clearly segregated from low-voltage cables (sensors) observing a distance of at least 100 mm

• Boiler

• Control panel

• Housing for wall mounting

3.5 Room unit QAA55…

Planning

The room unit should be located in the main living room while giving consideration to the following points:

• The place of installation should be chosen such that the sensor can capture the room temperature as accurately as possible without getting adversely affected by direct solar radiation or other heat or refrigeration sources (about 1.5 meters above the floor)

• In the case of wall mounting, there must be sufficient clearance above the unit, enabling it to be fitted and removed

When the unit is removed from its base, power is disconnected so that the unit is out of operation.

3.7 Wireless components

The wireless components should be located such that transmission will be as interferencefree as possible. The following criteria must be observed:

• Not in the vicinity of electrical cables, strong magnetic fields or equipment such as PCs, TV sets, microwave ovens, etc.

• Not near larger metal structures or constructional elements with fine metal meshes such as special glass or special concrete

• The distance to the transmitter should not exceed 30 meters or 2 floors

3.7.1 Radio module AVS71…

The radio module extends the product range through the introduction of wireless communication. With this type of device, system components such as room units transmit data with no need for using cables.

Planning

Do not install the radio module inside metal casings (e.g. inside the boiler).

Mounting method

2359Z23

Connection

The prefabricated cable must be connected to terminal X60 of the controller. Prior to connecting the module, the basic unit must be disconnected from power!

Radio link

Establishment of the radio link is described in the following sections which cover the different radio-controlled units.

Connection / power supply

The room unit is powered by three 1.5 V Alkali batteries type AA (LR06).

Radio link

Establish the radio link in the vicinity of the radio module prior to mounting so that all system components are within easy reach.

Prerequisite for the radio link is that all components receive power, which means that the radio module must be correctly connected to the basic unit and the batteries must be correctly installed in the room unit.

1. Press the button on the installed radio module for at least 8 seconds until the LED

on the radio module starts flashing at high frequency.

2. Press the OK button on the room unit to switch to programming.

3. Press the Info button for at least 3 seconds and select operating level

“Commissioning“ with the setting knob. Then, press the OK button.

4. Select operating page “Operator unit“ and press the OK button.

5. Select operating line “Used as“ (operating line 40) and make the appropriate

selection. Then, press the OK button.

6. Select operating page “Wireless“ and press the OK button.

7. Select operating line “Binding“ (line 120). Then, press the OK button.

8. Set the setting knob to “Yes“ and press the OK button. Link establishment is started.

9. The display shows the progress of link establishment in %. This process can take 2

to 120 seconds.

10. The link is established when “Unit ready” appears and the LED on the radio module

extinguishes.

The test is made to check the quality of the radio link.

• The test can be stopped by pressing the ESC button

• While the radio link can be opened on the boiler, the test should be made at the

location where the room unit will be installed

On the room unit, as described above (points 2 to 4), select operating page “Wireless“ and activate the test mode on operating line “Test mode“ (line 121).

Example of a display during the test:

The digits on the left show telegrams that have been sent, the digits on the right telegrams that have been received. The test will be ended after 24 telegrams. The test will be considered successful when at least 50 % of the telegrams sent have been received.

2359Z140

Operator sect ion Testmode

If the test was not successful, some other mounting location should be chosen or the AVS14.390 radio repeater should be used.

3.7.5 Checking the wireless components

To check whether the connections to the required system components are operational, consult operating lines 130 through 135 on operating page “Wireless“ (operating level “Commissioning“).

3.8 Power supply AVS16.290

Mounting notes

The boiler control panel is designed for installation in floor-standing or wall-hung oil or gas boilers and may only be used for that purpose. For installation, the following points must be observed:

• Power to the control panel may be supplied only after it is completely fitted in the cutout. Extension modules or dummy covers for which cutouts are provided must also be fitted beforehand

• Dimensions of cutout 92 x 92 mm, sheet metal thickness 0.5 to 3.0 mm

• The boiler control panel must be secured with the 4 clips provided on the panel

• Control panel wiring to the connection terminals does not feature strain relief so that

the cables must be secured inside the boiler

• Local regulations for electrical installation must be complied with
