Building Technologies Use 23 Sep 2011
Use
With the RXC room controllers, wireless room units can be used in place of the
QAX3x standard room units. One of the wireless technologies used is EnOcean.
Here, the room unit is powered by a solar cell. A battery is only needed If light
conditions are poor.
The gateway requires a separate AC / DC 24 V supply
(not in the scope of delivery).
Integration ot the EnOcean room units (QAX9x.x) into the system is made via the
RXZ95.1/LON EnOcean/LONWORKS gateway. It handles up to 9 EnOcean room
units. The telegrams received via radio are converted to LONWORKS standard
network variables (SNVT).

System requirements
SRC04-FTT plug-in (template: Thermokon srcn_9_1_02)
Functions:
Monitoring and configuration gateway / room units
For use with RXT10 tool or standard LNS tool
The device resource files contain information about supplier-specific configuration
parameters and network variables (UNVTs and UCTPs).
Prerequisite for installation is LONMARK® resource files version 13.00 or,
alternatively, LonMARK resource file API version 2.3 (bothersome installation).

LONMARK resource files version 13.00:
Download from http://www.lonmark.org/technical_resources/resource_files/
Environment for engineering tool
Integration of QAX95.x/QAX96.x: The RXT10 tool or a standard LNS tool can be
used.
Integration of QAX97.x/QAX98.x: A standard LNS tool must be used.
Limitations
With a DESIGO system, it is not possible to integrate additional EnOcean
products, such as buttons, presence detectors, etc., via the RXZ95.1/LON
gateway with the RXT10 tool.
Reason: In the gateway, temperature and setpoint adjustment are
available as static network variables. However, additional
functions are configured dynamically, and the RXT10 does not
support dynamic network interfaces.
RXT10 does not support the multifunctional button of the QAX97.4 und QAX98.4
room units.
For technological reasons, the control performance of an RXC… room controller
in connection with an EnOcean room unit is inferior to that with a standard
QAX3x room unit

With the default setting of 0.0 s (OFF) and in the event the RF link
breaks down (faults, no light, etc.), the temperature value in the RXC
will change to ”invalid” when the heartbeat has elapsed. When using a
setting greater than 0.0 s, the temperature value received last will be
transmitted.

Building Technologies Sources of errors 23 Sep 2011
Impact on the system:
T0 --
T1 All temperatures = 0.0 C after Power_fail / Power_up.
Room unit sends current temperature after about 20 to 30 minutes.
T2 RXC polls the gateway (0.0 C) and sends value to the system.
T3 Frost alarm (0.0 C). This state continues until all EnOcean room units
have transmitted a valid temperature. This takes about 20 to 30 min, but
may take longer than an hour should short breakdowns occur.
If a room unit does not send (e.g. exhausted), frost alarm is maintained until
that room unit sends as well.
With each simultaneous power failure of the RXC and the gateway, the
system triggers frost alarm for 20 to 30 minutes. The same applies to
power-up.

Building Technologies Mounting 23 Sep 2011
Mounting
The devices are supplied in an operational status.
Installation is made by means of anchors and screws (not included) to the smooth
wall surface, or by means of screws to an installation socket .
For operation a separate external 868 MHz receiving antenna is required (included
in delivery).
The antenna with magnet foot should be mounted on the center of a 180 mm x
180 mm metal plate (galvanized sheet steel).
In rooms the antenna should be mounted 1 m below the ceiling.
The antenna should be vertically aligned downwards.
Minimal distance to the wall: 90 mm.
Distance to other transmitters (e.g. GSM / DECT/ wireless LAN / EnOcean etc.):
min. 2 m.
The antenna cable shall be routed in an electric conduit.
Avoid crushing of the antenna cable.
The minimal bend radius of the cable is 50mm.
As for the cable installation, avoid the use of an active pull-up device, otherwise
the sheathing or on the connectors may damaged.
For details on positioning of the EnOcean room units, refer to data sheet
CM2N1660.
Commissioning
Wireless room units are sending time or event controlled telegrams to the gateway.
The gateway verifies the incoming telegrams and outputs them directly via its
LONWORKS interface.
Each telegram allows a precise allocation and consists of the format: type of the
telegram, data, sender ID (32bit).
In order to assure a correct evaluation of the measuring values by the gateway, it is
necessary to have the devices learned-in by the gateway. This is done automati-
cally by means of a “learn button” at the room unit (or manually by input of the 32bit
sensor ID) and a special “learning” procedure between room unit and gateway.
For details, refer to the data sheet of the EnOcean room units, CM2N1660.
In order to press the service pin, the lid must be opened.
Disposal
The device is classified as waste electronic equipment in terms of the European
Directive 2002/96/EC (WEEE) and should not be disposed of as unsorted
municipal waste.
The relevant national legal rules are to be adhered to.
Regarding disposal, use the systems setup for collecting electronic waste.
Observe all local and applicable laws.
