Part 4: Installation and Start-up

If the time has not been corrected after max. 10min,
select a different place of installation for the DCF (e.g.
another wall - not in proximity to TV devices, monitors or
dimmers).
PC
All system-specific parameters can be set and
interrogated using the

software. The parameters can be saved, displayed
graphically and evaluated on the PC at predefined
intervals. To connect to a PC, you need the CoCo PC
active, which also supports the sending of error
messages by SMS and the remote interrogation of
controller data.
System bus
This controller can be expanded in a modular fashion
using additional modules that are connected via the
integrated bus. In its maximum configuration, the system
can be used to control the following heating system
components
1-8 Boiler (modulating or switching)
1-15 Mixed weather-dependent heating circuits
0-15 Room controller (digital or analogue)
1
Solar system (2 collectors, 2 storage tanks)
1
Solid fuel boiler
The various components are simply coupled to the
system bus. The modules log on to the system
automatically and search for their communication
partners via the defined bus IDs (heating circuit number
or boiler number).
Bus ID
For mixer motor controllers and control units
The bus ID (00-15; expert level parameter) is used to
number the heating circuits in the system. Each operating
module and each mixer motor module is given the
number of the assigned heating circuit as its bus ID.
Heating circuit numbers (00-15) may not be assigned
twice.
Heating circuit numbers 00 and 01 may not be used
simultaneously.
The heating circuits are sequentially numbered
starting with "01".
Please only use heating circuit number 00 for
replacement controllers if "00" was used in the
replaced controller.

After setting all the bus ID's the system must be
reenergised (once only).

As-delivered condition = 5kOhm NTC sensor.
The start-up level for setting the installed sensors
appears once after switching on the power supply and
switching into operating mode. It can be reactivated again
by briefly switching the supply voltage off.
Exceptions:
The sensor inputs F13 + F14 must always be
operated using a PT1000 sensor.
Connecting an analogue remote control FBR is
detected automatically. Thus, the previous and the
new version can be connected to the controller.
The controller provides the option of performing a
room temperature guided control through the
connection of a room sensor to the FBR terminals 1
and 2. In this case, only a 5kOhm NTC sensor can be
used.
