Hold mode

The Hold mode of a controller is activated in two ways:
Calibration of the actual value
n
n If there is no enable signal, the release function is activated (see Agenda user level
"released y / n" or "additional enable input")
In Hold mode, the automatic control operation is stopped. The output level of the controller
is the preconfigured number (default = 0%), unless the accepting the Hold output is turned
off in the settings. In this case, the output level is frozen.
Only the setpoint can be changed in this mode. However, the setpoint change remains in
the Hold mode without effect. The amended target value reaches only when the controller
is returned to the automatic control mode.
The Hold mode has priority over the manual mode. If Hold mode is activated while the
controller is in manual mode, the controller goes from manual mode to hold mode, and the
hold operation returns to manual mode.

change in the currently active set point is incorporated
in the controller parameters. However, the output level
remains at 0% during Hold mode.
