7.8On/off control

The flow temperature can be controlled by an on/off signal. The controlled valve is opened when the flow temperature falls below the set point by T = 0.5 x Hysteresis. When the flow tem- perature exceeds the set point by T = 0.5 x Hysteresis, the control valve is closed. The greater the Hysteresis selected, the lower the switching frequency. The UP lag time parameter indicates the time span which the circulation pump continues to run after the control valve is closed (the pa- rameter only needs to be set for the heating circuits HK1, HK2 and HK3).

By entering Minimum activation time, a burner once switched on remains switched on for the time entered, regardless of how the temperature develops. Likewise, a burner that has been switched off due to the temperatures remains switched off for the time entered in Minimum de- activation time.

The on/off control can be configured separately for the individual heating circuits and for the pre-control circuit.

7.9Continuous-action control

The flow temperature can be controlled using a PID algorithm. The valve receives an analog 0 to 10 V signal issued by the controller. The proportional-action component causes an immediate change in the 0 to 10 V signal when a system deviation arises (the larger the KP, the greater the change). The integral-action component first affects the control after a certain time: TN stands for the time that passes until the I-action component has changed the output signal so far as the P-action component just did (the larger the TN, the slower the rate in change). The D-action com- ponent causes every change in system deviation to have any increased effect on the output sig- nal (the larger the TV, the more intensified the change).

The continuous-action control can be configured separately for individual heating circuits, for the DHW heating and for the pre-control circuit.
