2 x Product description
2.1 General
The Control RoCon BF is a constituent part of the boiler
control panel in ROTEX Heat generator.
It consists of the control panel PCB, the actors and
sensors and other components of the ROTEX regulating system RoCon connected and the operating unit
RoCon B1.
In this instruction manual we explain just the functions
and setting possibilities of the Control. More information
for the boiler control panel and containing the
equipment components can be found in the supplementary documents.
The electronic, digital Control is able to automatically control all
heating and hot water functions for the direct heating circuit, a
mixed heating circuit which can be connected as an option and a
storage tank charging circuit, depending on the boiler in question.
Together with the automatic firing unit it takes over the entire
safety management of the ROTEX Heat generator. This executes a safety switch-off in the event of a water shortage or undefined operating states. A corresponding fault message shows
the operator all the information for fault causes.
All function settings for the ROTEX Heat generator and the optional RoCon equipment connected via the data bus are carried
out with the operating elements of the integrated operating part
RoCon B1 and displayed in clear text display on a coloured
backlit display.
On the ROTEX Heat generator the regulation data bus is used to
connect the following optional equipment:
– Room station RoCon U1 ( 15 70 34).
–Mixer module RoCon M1 ( 15 70 68).
The room station RoCon U1 has the same operating panel as the
one integrated in the Heat generator (the RoCon B1).
All settings for the allocated heating circuit can be carried out in
the same way as the operating unit. With activated terminal
function, all operating possibilities that are available on the integrated operating unit are available, with the exception of certain
special functions (e.g. Emission Measurement).
A connected mixer module RoCon M1 will also be operated, after
appropriate allocation, by the control unit RoCon B1 and/or the
room station RoCon U1.
2.2 Display and operating elements
01.04.13
13:35
Using the connected outdoor temperature sensor RoCon OT1
( 15 60 70) you can regulate the flow temperature in a
weather-controlled manner with a frost protection function.
If the optional gateway RoCon G1 ( 15 70 56) is installed and
connected to the internet, the ROTEX Heat generator can be
conveniently monitored and operated by remote control using a
mobile phone (App).
The Control RoCon BF contains a timer, which can be used to
set:
– 2 individually-adjustable timer programmes for room heating
(direct heating circuit),
– 2 individually-adjustable timer programmes for hot water gen-
eration,
– 1 individually-adjustable timer programme for an optional cir-
culation pump.
In addition, the Control RoCon BF has a frost protection unit for
the direct heating circuit and the storage tank charging circuit, together with the facility for incorporation of an additional heat
source (wood-burning boiler, solar system) via a potential-free
burner blocking contact.
Initial commissioning of the heating system unit is described in
the installation manual of the ROTEX Heat generator.
Certain menu points on the Control RoCon BF are only accessible to the heating expert. This security measure ensures that no
undesirable malfunctions arise during operation of the system
through incorrect settings.

3.3.1 Emissions measurement
Caution - danger of overheating with
underfloor heating!
In the event of a fault, or in hand mode, damage may
be caused to the screed, the structure of the floor and
the underfloor heating system by overheating.
Ɣ Before commissioning for the first time, set the
maximum permissible system temperature in the
maximum temperature limit in the Control
RoCon BF (parameter [Max T-Flow]).
During the emission measurement the flow temperature of the
Heat generators is limited to the value set in the parameter [Max
T-HS]. With additionally connected external heating circuits, the
Control RoCon BF attempts to keep the current flow temperature
in the heating circuit between 55 °C and 65 °C.
In order to cool or bring the Heat generator as quickly
as possible to temperature during emission measurement, we can impose a forced drop-off or a drop-off
block in the heating circuits using the Heat generator
(parameter [Forced Performance]). This parameter can
be used to set whether the heating circuit should react
to the drop-off demand or not.
Ɣ Depress the exit button for at least 5 secs.
Î Menu "Special Level" is displayed.
Ɣ Select the programme "Emission Measurement" with the
rotary switch.
Ɣ Confirm the changes with a brief push of the rotary switch.
Î The following load types are available for selection:
– Off: Emission measurement is switched off, any Control-
connected Heat generator that is switched on continues to
be regulated normally.
– Base Load: The Heat generator is switched on and oper-
ated at the minimum output of the Heat generators, irrespective of the set operating mode.
– Full Load: The Heat generator is switched on and oper-
ated at the maximum output of the Heat generators, irrespective of the set operating mode.
Ɣ Select the load type "Full Load" using the rotary switch, but
do not confirm it.
Î Display: "Full Load"

3.3.2 Manual Operation
The manual mode serves to regulate the Heat generator manually to a specific flow temperature. The manual mode should
only be used for diagnostic purposes.
With hydraulically controlled priority operation for the hot water
generation you must make sure that the flow temperature set in
manual mode is adequate to achieve the stored hot water set
temperature (parameter [Room Temp Reduced]).
During active manual mode the hot water is consistently regulated to the first set value parameter of hot water generation
([Room Temp Reduced]).
When the manual mode is ended, the Control RoCon BF auto-
matically switched to the operating mode "Standby".
