Mounting and installation Mounting the central apartment unit Mounting regulations

• The central apartment unit is designed in compliance with safety class II and must be mounted accordingly.

• Power may be applied to the unit only when completely mounted. Otherwise, there is a risk of electric shock by the connection terminals.

• The unit must not be exposed to dripping water. • The permissible environmental conditions specified in the

technical data must be observed (refer to Data Sheet N2707en).

• Sufficient space must be provided for fitting / removing the unit cover and for connecting the service tool (> 70 mm below and > 10 mm above the unit).

Mounting location The central apartment unit consists of electronics section and base. The base is designed for wall mounting (on an interior wall of the apartment). We recommend to mount the unit in an easily accessible space (e.g. in the living room or the lobby). For convenient operation, the recommended mounting height is 1.5 m above the floor.

2707Z31

> 70

mm

> 10

mm

1.5

m

The central apartment unit communicates with most system compo-nents via radio. To ensure optimum radio coverage, the following points should be observed:

• The distance to devices with electromagnetic emissions, such as wireless telephones, TV sets, PCs, microwave appliances, etc., should be at least 1 m

• Larger items made of steel or construction elements with me-tal meshes (e.g. special glass or concrete), or metal foils in thermal insulation materials, mirrors or metal-coated heat absorbing glass, can have an impact on the range

9/88


• The typical range between transmitter and receiver in resi-dential buildings is 30 m, or across 2 floors, or 2 concrete ceilings. But depending on the type of house or building and the materials used, the effective range can be considerably greater or smaller. If greater distances are to be covered, RF repeaters should be used

The setting's impact equally depends on the actuator type used as described in "Valve position cooling mode / summer operation“ (see below).

Room temperature rise During optimum start control, the central apartment unit ascertains the room temperature rise (min / K) of the respective room and takes it into account the next time optimum start control is performed. The value calculated last can be viewed via an operating line and can be changed, if required:

Main menu > Heating > Room X > Room settings > Room temp rise:

Proportion room unit If a QAW910 room unit and 1 or 2 QAA910 room temperature sen-sors are connected to the same room, the room unit’s weighting (0..100 %) with regard to room temperature averaging can be set.

If 1 room unit and 1 room temperature sensor are used, the actual value of the average room temperature is determined based on the percentage proportion set.

If 1 room unit and 2 room temperature sensors are used, the average value of the 2 room temperature sensors is determined first. Then, the actual value of the average room temperature is calculated based on the percentage proportion set for the room unit and the room tem-perature sensor.

When 2 room temperature sensors are used, the average value of the 2 sensors is delivered. The proportion of the individual sensors cannot be changed.

Main menu > Heating > Room X > Room settings > Proportion room unit:

Factory setting 50 % Your setting

Valve position cooling mode / summer operation This determines the position to which the valve of a room is driven (0..100 %) when the plant is switched to cooling mode or summer operation. The amount of cooling energy drawn by the individual rooms can thus be influenced.

In rooms with high humidity levels, there is risk of condensa-tion.

The setting has the following effect in dependence of the actuator type used: RRV912: 3-point actuator The actuator exactly arrives at the set position. RRV918 / RRV912: 2-point actuator (NC / NO) The actuator is not controlled with setting 0..49% and remains in the start position (for NC = 0%). The actuator is controlled by a permanent pulse with setting 50..100% and thus remains in the end position (for NC = 100%). SSA955 The actuator exactly arrives at the set position.

Minimum valve position Comfort To prevent cold floors in the case of floor heating systems, a mini-mum valve position (0..100 %) can be fixed which is observed during Comfort periods, even if the room temperature is sufficiently high. It is accepted that in such cases the room might get overheated.

Data backup The current commissioning data can be saved, including the date and the year. The data saved or the factory settings can be retrieved, if required.

Main menu > Data backup > Storage date (read only): Main menu > Data backup > Storage year (read only): Main menu > Data backup > Restore: Main menu > Data backup > Save: Main menu > Data backup > Restore factory setting:

When saving the new data, any data previously saved in the backup storage is overwritten (cannot be retrieved). When restoring data or the factory settings, the current data set in the device’s main storage is overwritten (cannot be retrieved). When restoring data, certain bus settings and all texts set are not overwritten and are therefore retained with their present state. When restoring the factory settings, customized texts are also reset.
