Night set point 30 °C Top, middle / Min. to max. flow temperature
Parameters
WE Parameter level / Range of values
Min. flow temperature 20 °C PA1, 2 / 5 to 130 °C
Max. flow temperature 90 °C PA1, 2 / 5 to 130 °C
Note!
A fixed set point control in heating circuit 2 with CO2 -> F02 - 0 can only be configured if
CO1 -> F02 - 0 is set as well, because the heating circuit 2 with CO2 -> F02 - 0 only uses
the measured outdoor temperature provided by heating circuit 1.
5.3 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 range of values
of the heating characteristic gradient and the maximum flow temperature in parameter lev-
els PA1, 2:
4
Range of values of the gradient: 0.2 to1.0
4
Range of values 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 always starts with a flow
temperature of 25 °C. In the course of 24 hours, this temperature is raised by the value en

, i.e. the default setting causes the temperature to rise to 30 °C
within the first 24 hours. If the
