The ΔT can be increased with a parameter setting. When increasing the
ΔT, the control unit limits the flow temperature to a maximum of 80 °C.

2. If a PWM-controlled central heating-pump is controlled by the boiler
control unit; set parameter PP014 to 2 °C.
4.7.4 Settings for open-vented application
For this application, adjust the following parameter:
1. Set parameter DP006 to 0,0 bar.
2. Set parameter GP021 to 20°C.
4.7.5 Screed drying
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.
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.
