8.8 Continuous control in control circuit RK1
The ow temperature in the control circuit RK1 can be controlled using a PID algorithm. The
valve in RK1 control circuit receives an analog 0 to 10V signal from the controller. When a
system deviation occurs, 'KP (gain)' immediately causes the 0 to 10V signal to change (the
greater the KP, the greater the change). The integral component becomes effective with time:
'Tn (reset time)' represents the time which elapses until the integral component has changed
the output signal to the same extent as the immediate change performed by the proportional
component (the greater Tn is, the slower the rate of change will be). Due to the derivative
component, any change of the system deviation is incorporated into the output signal with a
certain gain (the greater TV is, the stronger the change will be).

8.9 Releasing a control circuit/controller with binary input
The release of an individual control circuit or the controller with the binary input only be-
comes effective when the respective control circuit is in automatic mode (
icon). The re-
leased control circuit always works in automatic mode; the deactivated control circuit be-
haves as if it were transferred to stand-by mode. It remains active, however, in any case for
processing an external demand. The control circuit can be released by the binary input when
the binary input is either a make contact ('Active when BI' = OFF) or a break contact ('Active
when BI' = ON).
Note:
− In systems with downstream heating circuit without a valve (Anl 2.x, 4.x), BI1 only
inuences the operation of this heating circuit.
− In system Anl 3.0, BI1 inuences the operation of the entire controller (except for
processing an external demand).
