Underfloor heating/drying of jointless floors

Using function block setting CO1, 2 -> F05 - 1, the respective heating circuit is configured as an
underfloor heating circuit. In doing so, the controller at first only limits the value ranges of the
heating characteristic gradient and the maximum flow temperature in PA1, 2 parameter levels:
4
Value range of the gradient: 0.2 to 1.0
4
Value range of the maximum flow temperature: 5 to 50 °C
In addition, it is possible to activate the Drying of jointless floors function. In connection with
this, the function block parameters are listed which appear after activating this function block.
They determine the drying process: the first heating up phase starts at the entered Start tempera-
ture , which has a flow temperature of 25 °C in its default setting. In the course of 24 hours, this
temperature is raised by the value entered in Temperature rise , i.e. the default setting causes the
flow temperature set point to rise to 30 °C. If the Maximum temperature is reached, it is kept
constant for the number of days entered in Maintaining time for maximum temperature . The
Temperature reduction determines the temperature reduction downwards. If the Temperature
reduction is set to 0, the temperature maintaining phase moves directly to automatic mode.
The drying function is activated by changing the setting STOP to START temperature build-up
n

can be selected to continue an interrupted drying process. The course of the drying process can
be monitored in the information level over the icon of flow temperature display (

The drying process has been successfully completed when the additional icon in the flow tem-
perature display goes out after the last phase.
STOP on the display indicates that there has been a deviation of flow temperature of more than
5 °C for longer than 30 minutes. The function is canceled by the controller in such cases. While
STOP appears on the display, the controller keeps the flow temperature constant at 25 °C.
