For this application, adjust the following parameter:
The screed drying function is used to force a constant flow temperature or
a series of successive temperature levels to accelerate screed drying on
underfloor heating.

2. If a PWM-controlled central heating-pump is controlled by the boiler
control unit; set parameter PP014 to 2 °C.
1. Set parameter DP006 to 0,0 bar.
2. Set parameter GP021 to 20°C.
Important
The settings for these temperatures must follow the screed
layer's recommendations.
Activation of this function via the parameter CP470 forces the
permanent display of the screed drying function and deactivates
all other regulator functions.
When the screed drying function is active on one circuit, all
other circuits and the domestic hot water circuit continue to run.
It is possible to use the screed drying function on circuits A and
B. The parameter settings must be made on the PCB that
controls the circuit concerned.

Important
Every day at midnight, the screed drying start temperature set
point is recalculated and the remaining number of days on which
the screed drying function is running decreases.
