Tab.56 Settings
A Slope: Slope of the heating curve:
B Max: Maximum temperature of the heating circuit
C Base: Ambient temperature setpoint
D xx°C ; xx Relationship between the heating circuit flow
°C temperature and the outdoor temperature. This
information is visible throughout the slope.

Setting for process heat application

Important
The service life of the boiler may be reduced if it is used for
process heat applications.
For this application, adjust the following parameters:
1. Set parameter DP140 to Process heat.
Floor heating circuit: slope between 0.4 and 0.7
Radiator circuit: slope at approximately 1.5
