3.5 Special functions
Different functions (mostly useful functions for the heating expert)
can be carried out on the
"Special Level"
.
The following special functions are possible:
– Emission measurement (see chap. 3.5.1)
– Manual operation (see chap. 3.5.2).
– STL test (see chap. 3.5.3)
– 3-way switching valve reference travel
– Error display (see chap. 7)
– Reset to factory settings (see chap. 3.6.6)
Detailed explanations of these functions can be found in chap. 6.11.
● Push the Exit button for at least 5 s.

The
"Special Level"
menu is displayed.
● Use the rotary button to select the program to be started.
● Confirm the selection with a brief push of the rotary button.

The selected program starts.
● Cancellation and jump back by:
– pressing the Exit key again or
– touching the rotary button or
– selecting another menu using the rotary switch.
3.5.1 Emission measurement
During the emission measurement, the T-HS of the heat gen-
erator is limited to the value set in the [Max T-HS] parameter. For
additionally connected external heating circuits, the RoCon BF
control unit tries to keep the current T-HS of the heating circuit at
temperatures between 55 °C and 65 °C.
● Push the Exit button for at least 5 s.

The
"Special Level"
menu is displayed.
● Use the rotary button to select the
"Emission Measurement"
program.
● Confirm the selection with a brief push of the rotary button.

The following load types are available for selection:
–
Off:
The emission measurement is switched off, the heat
generator that may have been switched on by the control
unit continues to run normally.
–
Base Load:
The heat generator is switched on and oper-
ated at the minimum output of the heat generator, irre-
spective of the set operating mode.
–
Full Load:
The heat generator is switched on and oper-
ated at the maximum output of the heat generator, irre-
spective of the set operating mode.
● Use the rotary button to select the
"Full Load"
load type,
but
do not confirm it
.

Display:
"Full Load"

The burner is switched on for 30 min and controlled to
the specified maximum temperature.

The burner is switched on for 30 min. and is regulated
at maximum load.
● Use the rotary button to select the
"Base Load"
load type,
but do not confirm it
.

Display:
"Base Load"

The modulating gas burner runs at minimum output for 30
mins.
● Cancellation and jump back by:
– Again pressing the Exit key or the rotary button
– Use the rotary button to select a different menu and con-
firm.
The calling-up of the special functions does not depend
on the rotary switch setting.
Caution - Risk of overheating of floor
heating!
In the event of malfunction or during manual
operation, the floor heating, the screed or the
floor structure could be damaged due to over-
heating.
● Prior to initial commissioning, set the
maximum temperature limit in the RoCon BF
control unit ([Max T-Flow] parameter) to the
maximum permitted system temperature
prior to starting the emission measurement.
To cool the heat generator during the emission meas-
urement or to bring it up to temperature as quickly as
possible, an acceptance obligation or an acceptance
block can be imposed on the heating circuits by the heat
generator ([Forced Performance] parameter). This parameter
can be used to set whether the heating circuit should react to the
acceptance requirement or not.
