• Version: 11.06.2018 • Technical changes and errors excepted.
Now specify what should be sent when the control is blocked.
On release, the control variable follows the rule again.
In case of a common control variable for heating and cooling, 0 is always transmitted
as a fixed value.
PI control with predetermined application:
This setting provides fixed parameters for a cooling ceiling
Now specify what should be sent when the control is blocked.
On release, the control variable follows the rule again.
2-point-control (only level 2):
2-point-control is used for systems which are only set to ON or OFF.
Enter the hysteresis that prevents frequent on/off switching of temperatures in the th-
reshold range.
If separate control variables are used, select whether the control variable of the 2nd le-
vel is a 1 bit object (on/off) or an 8 bit object (on with percentage/off).
When blocked, the control variable shall
• not be sent
• send a specific value
Value (in %)
(if a value is sent)
