Explanations
Controller amplification for functions 5 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 "0D".

Explanations
Controller reset time for functions 5 and 6
The greater the reset time, the more stable but slow-
er the controller.

Explanations
Reference temperature differential for function 7:
Reference temperature differential for temperature
differential between common boiler return tempera-
ture and common system return temperature of all
heat generators upstream of low loss header
If the temperature differential exceeds the refer-
■
ence temperature differential, the circulation pump
speed increases.
If the temperature differential falls below the refer-
■
ence temperature differential, the circulation pump
speed decreases.
