Operation
Screed curing heating
The drying process for the screed cannot be exactly predicted. If
there is a high degree of humidity, sometimes it can stop com-
pletely. The drying process can be speeded up by activating the
floor heating (screed curing heating) or measures such as me-
chanical drying.
Each screed curing heating must be ordered separately by the
client as an extra service in accordance with German con-
struction contract procedures (VOB). The workability of the
screed is a prerequisite for beginning the work of the top floor in-
staller, so that he can produce defect free work.
With standard settings, the combined function and screed curing
heating program can be activated to achieve the required re-
sidual moisture in the screed for screed curing (see fig. 3-19).
However, the residual moisture of the screed must basically be
checked metrologically before the flooring can be laid.
More detailed explanations and possible setting values for this function can be
found in chapters 6.2.3 and 6.13.2.
Setting and starting the screed program
The screed program already includes factory default values
which can, however, be individually adjusted.
The day on which the screed program is activated is not counted
in the runtime of the program. The 1st day starts at the change of
day at 00:00 am. On the day of activation, the setting of the 1st
program day is used for heating for the remaining time.
●
Enter the technician code (see chap. 3.6.1).
After entering, the
"Setup"
level is displayed.
●
Use the rotary button to select the parameters [Interlink fct]
and [Room thermostat] and check whether they are deacti-
vated (see tab. 6-1).
Both parameters must be set to "Off" before starting the
screed program.
●
Briefly press the Exit button.
An overview is displayed.
●
Use the rotary button to select the
"HC Configuration"
level.
An overview is displayed.
●
Use the rotary button to select the [Screed Program]
parameter.
●
Check the settings for the screed program, and set according
to the manufacturer specifications for the screed if necessary
(see fig. 3-20).
– The adjustment range always lies between 0.0 and 65 °C.
– The increment is 1 °C.

●
Briefly press the Exit button.
An overview is displayed.
●
Use the rotary button to select the [Screed] parameter.
●
Confirm the selection with a brief push of the rotary button.
The setting of the parameter is displayed.
●
Use the rotary button to set the parameter for the function to
"On"
, and confirm by pressing the rotary button briefly (see
Screed program starts.
The key lock (if it was activated prior to the start of this
function) is reactivated within 2 s to prevent undesired
cancellation of the function through operation of the
RoCon mb controller.
After the screed program has ended, the RoCon mb control unit
continues to work in the previously set operating mode. If not con-
figured beforehand, the following finishing work is necessary.
a) On connection without room station:
●
Set the heating characteristic curve or desired target feed
temperature.
b) On connection with room station:
●
Activate the room station.
●
Set the heating characteristic curve or desired target feed
temperature.If necessary, activate the parameter [Room
Influence] and set the target room temperature.
