The room units:

the key to individual comfort

The room units in the Desigo RXC range cover a wide variety of needs represented by

the various room occupants. When designing these stylish room units, the designers

also paid special attention to ergonomic factors.

The HVAC system, lighting and blinds can be operated in various ways:

• In the conventional manner, with standard room units for HVAC, and electric

switches to control lighting and blinds

• With the integrated room unit, which combines the operation of HVAC, lighting and

blinds in a single device.

• With wireless room units, which offer scope for location anywhere in the room, and

permit averaging.

Conventional room units

The standard room units, types QAX30.1 ... QAX39.1, are available for HVAC appli-

cations. They are connected to the room controller via a special (PPS2) interface. In

addition to the built-in temperature sensor, all room units incorporate a socket for the

RXT10 commissioning and service tool.

For applications involving the control of lighting and blinds, conventional switches can

be used. This option is primarily of interest in systems retrofitted with Desigo RXC.

Integrated room units

The QAX50 and QAX51 flexible room units combine the operation of HVAC, lighting

and blinds in a single device. The functions of each room unit are defined with appli-

cation software in accordance with the room configuration. The room units are then

fitted accordingly with the appropriately labeled pushbuttons. These integrated room

units communicate with the room controllers via the LON bus.

Flush mounting room units with elegant design

The QAX84.1/PPS2room unit can be used in connection with standard switches and for

in-wall mounting. It is delivered with a Siemens Delta-I bezel, but can also be ordered in

separate components to fit in bezels from various manufacturers:

Operator unit (QAZ84.1) and PPS2 flush mounting bus coupling unit (RXZ80.1 / PPS2).

Wireless room operation

The wireless room units, types QAX90.1 and QAX91.1 are used in conjunction with the

RXZ90.1 receiver (PPS2). They are ideal for:

• Use in renovation projects (no wiring required)
