• Status: 19.10.2016 • Errors excepted. Subject to technical changes.
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).
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.
6.16. Summer Compensation
With the summer compensation the target value for the room temperature can auto-
matically be adapted by cooling at higher outdoor temperatures. The objective is to
prevent a too great a difference between indoor and outdoor temperature in order to
keep the energy consumption low.
Maximum control variable is reached

Cooling ceiling: 5
Reset time (in min.)
Cooling ceiling: 30
