9.5.1. Heating control stage 1/2
If a heating control mode is configured, one or two setting sections for the heating
stages are displayed.
In the first stage, heating is controlled by a PI controller which allows to either enter
control parameters or select predetermined applications.
In the second stage (therefore only in case of 2-stage heating), heating is controlled via
a PI or a 2-point-control.
In stage 2, the setpoint deviation between the two stages must also be specified, i.e.
beyond which setpoint undershoot the second stage is then added.
PI controller 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. In case of a short reset time, the control responds with a fast increase of the con-
trol 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 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 stage, e.g. for floor heating.
On release, the control variable follows the rule again.
