reached. You should set the time appropriate to the cooling system at this point (ob-
serve manufacturer's instructions).
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 stage 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.
