• Version: 17.11.2016 • Technical changes and errors excepted.
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.
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 frequent applications.

2-point-control (only level 2):
2-point-control is used for systems which are only set to ON or OFF.
When blocked, the control variable shall
