Ready-to-apply heating
The drying out procedure for the screed cannot be predicted ex-
actly in advance. At higher humidity levels in the air this can come
to a complete stop under certain circumstances stop under
certain circumstances. The drying out process may be acceler-
atedby running the underfloor heating (curing heating) or by
using measures such as mechanical drying.
Every curing heating process must be commissioned, separately
by the building owner as an extra service in accordance with
VOB. For the flooring contractor to achieve fault-free installation,
the flooring must be properly cured before work is started on the
top flooring layer.
The standard settings can be used to activate the combined
function and curing heating programme in order to achieve a re-
sidual moisture level in the screed required for curing the floor
(see fig. 3-19). The residual moisture level in the screed must,
however, always be checked by measurement before the floor-
covering is laid.
Fig. 3-19 The time sequence of the Screed Program in combined func-
tion and curing heating (for legend see fig. 3-18)
More detailed explanations and possible setting values for this function can be seen
in sections 6.2.3 and 6.13.2.
Screed Program setting and starting
The Screed Program contains factory-set specifications which
can, however, be individually adapted.
Screed Program The day on which the screed function is
activated does not count towards the runtime of the screed
programme. The 1st. The day begins with the change of the day
at 00:00. On the day of activation we heat the remaining time at
the programme of the first day.
● Enter the expert code (see section 3.6.1).

● Using the rotary push button, select and check the param-
eters [Interlink fct] and [Room thermostat] whether they are
deactivated (see tab. 6-1).

Both parameters must be on "Off" before starting the
screed function.
● Press the Exit key briefly.

An overview is displayed.
● Select the "HC Configuration" level with the rotary switch.

An overview is displayed.
● Select the [Screed Program] parameter using the rotary
switch.
● Check the Screed Program settings and adjust to the stipula-
tions provided for the screed by the manufacturer, if
necessary (see fig. 3-20).
– The setting range is always between 0.0 and 65 °C.
– The steps are 1 °C.

● Press the Exit key briefly.

An overview is displayed.
● Select the "Screed" parameter using the rotary switch.
● Confirm the changes with a brief push of the rotary switch.

The setting for the parameter is displayed.
● Using the rotary switch, set the parameter for the function to
"On" and confirm by pressing it quickly (see fig. 3-20).

Screed Program starts.

The button block (if it was activated from the start of this
function), is activated again within 2 seconds in order to
prevent inadvertent termination of the function by operat-
ing the Controller RoCon HP.
After expiry of the Screed Program the Controller RoCon HP
again operates in the previously set operating mode. Unless con-
figured previously, the following tasks need to be carried out in
conclusion.
a) When connecting without a room station:
● Set the heating characteristic curve or the inflow target
temperature.
b) When connecting with a room station:
● Activate the room station.
● Set the heating characteristic curve or the inflow target
temperature. If required, activate the parameter [Room
Influence] and set the target room temperature.
