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.
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
threshold range.
If separate control variables are used, select whether the control variable of the 2nd
level 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. 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.
6.5.2. Cooling control level 1/2
If a cooling control mode is configured, one or two setting sections for the cooling lev-
els are displayed.
In the 1st level, cooling is controlled by a PI control in which either control parameters
can be entered or predetermined applications can be selected.
Reset time (in min.)
Warm water heating: 150
Floor heating: 240
Convection unit: 90
Electric heating: 100
When blocked, the control variable shall
• not be sent
• send a specific value
