Screed drying
Settings - Screed drying
Set this parameter for each installed heating
circuit.
Function [Screed]
For each heating circuit, the function block text menu
contains the necessary settings for the screed drying
program.
With the [Incr. by] and [Incr. every] parameters,
you can set the interval for the incremental
increase in the flow temperature (factory setting 3°C
every 24 hours).
If the maximum temperature [Max. temp.] has been
reached, it is held for a period of [Retain max. temp.].
This is followed by an incremental reduction in tem-
perature. This is configured with the [Set-back by] and
[Set-back every] parameters (factory setting 3 °C
every 24 hours).

Set the start of the drying program with the [Start
screed drying] parameter. If the maximum temperature
is held for the configured duration, the program ends
as soon as the [Flow target] temperature is below the
[Flow] or the current room temperature.
You may change the calculated target
temperature [Flow target] at any time, in order to
commence heating with a higher temperature, for
example.
