Explanations
With the burner running at the set maximum output,
the circulation pump delivers the maximum flow rate.
Flow rate at maximum burner output
Explanations
Set temperature differential value between the set
boiler water temperature and set target temperature
for functions 2 and 6.
The circulation pump speed controls the target tem-
perature in such a way that the target temperature re-
mains below the boiler water temperature by the tem-
perature differential set here.
Setting effect:
Large temperature differential:
■
Stable temperature level in system, with possible
continuing deviation from set target temperature
Small temperature differential:
■
Rapid matching of the temperature level in the sys-
tem to the set target temperature. This may result
in large temperature fluctuations in the system.

Explanations
Controller amplification for functions 2 and 6
The higher the value set here, the more strongly the
controller will react to deviations from the set differen-
tial temperature specified at parameter "07".

Explanations
Controller reset time for functions 2 and 6
The greater the reset time, the more stable but slow-
er the controller.
