PI control with control parameters:
This setting allows individual input of the parameters for PI control.
Specify the deviation from the setpoint value at which the maximum control variable
value is reached, i.e. the point at which maximum heating power is activated.
The reset time shows how quickly the controller responds to deviations from the set-
point value. In case of a short reset time, the control responds with a fast increase of
the control variable. In case of a long reset time, the control responds somewhat less
urgently and needs longer until the necessary control variable for the setpoint value
deviation is reached.
You should set the time appropriate to the heating system at this point (observe man-
ufacturer's instructions).
Now specify what should be sent when the control is blocked. Set a value greater 0
(=OFF) to receive a basic heating level, e.g. for floor heating.
On release, the control variable follows the rule again.
PI control with predetermined application:
This setting provides fixed parameters for frequent applications.
