Different applications support different valve actuators, and these do not all require the
same number of outputs on the controller. The tool displays the actuators suitable for
the selected application. The valve type must be selected at the engineering stage (see
page 85).
Changeover is only possible if the control sequence parameter is set to changeover.
In this case, a changeover command (heating or cooling) is essential. In the absence of
the required information (e.g. due to problems with data communication), the controller
operates as follows:
After a reset, the controller operates in heating mode until another changeover
command is received.
If the transfer of data is interrupted, the controller remains in the last valid room
operating mode.
