8.8 Continuous control
The flow temperature can be controlled using a PID algorithm. The valve receives a 0 to 10 V
signal from the controller. When a system deviation occurs, the proportional component imme-
diately causes the 0 to 10 V signal to change (the greater K
P
, the greater the change). The inte-
gral components becomes effective with time: T
N
represents the time which elapses until the inte-
gral component has changed the output signal to the same extent as the immediate change per-
formed by the proportional component (the greater T
N
, the slower the rate of change). Due to
the derivative component, any change of the system deviation is incorporated into the output
signal with a certain gain (the greater T
V
, the stronger the change).

8.9 Unlocking a controller/control loop 1 over the binary input
The unlocking of the control circuit or controller using the binary input only becomes effective
when the control circuit or controller is in automatic mode.
An active control circuit or controller always works in automatic mode, whereas the deactivated
controller behaves as if it were switched to stand-by mode. It remains active, however, in any
case for processing an external demand. The controller can be unlocked over the binary input
S5 when the binary input is either a make contact (switching state of the controller or control
loop 1 active = 0) or a break contact (switching state of the controller or control loop 1 active
= 1).
