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.

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.
Activate the summer compensation.
Using the points 1 and 2, define the outdoor temperature range in which the target
value for the indoor temperature is to be adapted linearly. Then, specify which indoor
temperature target values are to be valid below point1 and above point 2.
Standard values according to DIN EN 60529
Point 1: External temperature = 20°, Target value = 20°C.
Point 2: External temperature = 32°, Target value = 26°C.
