5.3 Underfloor heating/drying of jointless floors
Using function block setting CO1, 2, 3 -> 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, 3 pa-
rameter 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 temperature , 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 de-
fault setting causes the flow temperature set point to rise to 30 °C. If the Maximum tempera-
ture 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
phase (
n
START
on the display). The restarting stages
START temperature maintaining phase
(
nn
START
on the display) and
START temperature reduction phase
(
nnn
START
on the dis-
play) 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
( ) of the associated heating circuit:
Temperature build-up phase
Temperature maintaining phase
Temperature reduction phase
The drying process has been successfully completed when the additional icon in the flow
temperature 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 con-
stant at 25 °C.
A power failure while the drying function is active or when
STOP
appears on the display au-
tomatically leads to the drying function restarting from the beginning.
