7.8 Continuous controlThe flow temperature can be controlled using a PID algorithm. The valve receives an analog0 to 10 V signal. When a system deviation occurs, the proportional component immediatelycauses the 0 to 10 V signal to change (the greaterK P , the greater the change). The integralcomponents 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 changeperformed by the proportional component (the greaterT N , the slower the rate of change).Due to the derivative component, any change of the system deviation is incorporated into theoutput signal with a certain gain (the greaterT V , the stronger the change).Functions WE ConfigurationControl modethree-step/0 to 10 V12.0120 sec0 sec45 secCO1, 2, 3, 4 -> F12 - 1, Y_KP (proportional gain) / 0.1 to 50.0TN (reset time) / 1 to 999 secT V (derivative-action time) / 0 to 999 secT Y (valve transit time) / 5, 10, 15, ..., 240 sec7.9 Releasing a control circuit/controller over the binary inputThe release of an individual control circuit or the controller using 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 forprocessing of external demand. The control circuit can be released using the binary inputwhen the binary input is either open (bE = 0) or closed (bE = 1).Note: In systems with supplementary heating circuit without a valve (Anl 2.x, 4.x), BE15 onlyinfluences the operation of this heating circuit when the release Rk1 function is configured,while the operation of the entire controller (except for processing of an external demand) isaffected when the release controller function is configured. In systems which only have sup-plementary heating circuits with or without DHW heating (Anl 3.x, 5.x), BE15 influences theoperation of the entire controller (except for processing of an external demand).Functions WE ConfigurationRelease Rk1 at BE15 0 CO1 -> F14 - 1*Release Rk2 at BE16 0 CO2 -> F14 - 1*Release Rk3 at BE17 0 CO3 -> F14 - 1*EB 5579 EN 99System-wide functions
