The Parallel relay function can be used to opera-
te an allocated parallel relay alongside a selected re-
ference relay. With this function, e. g. a valve can be
controlled in parallel to the pump via a separate relay.
If the Overrun option is activated, the parallel relay
remains switched on for the adjusted duration time
after the reference relay has been switched off.
If the Delay option is activated, the parallel relay will
be energized after the adjusted duration has expired.
If the reference relay is switched off again during the
delay time, the parallel relay will not be switched on
at all.
If the Inverted option is activated, the parallel relay
switches on when the reference relay switches off and
vice versa.

The mixer function can be used to adjust the actual
flow temperature to the desired mixer target tem-
perature TMixer. The mixer is opened or closed in
pulses depending on this deviation. The pulses are
determined by the adjustable Interval. The pause is
determined by the difference between the actual va-
lue and the set value.
The mixer runtime can either be adjusted in the
channel Runtime or automatically adapted with the
Offset function. When Offset is selected, the mixer
will close first. When button

is pressed, the mixer

opens and the seconds are counted in the display. As
soon as the mixer has reached its open position, press
button

again. The time measured will automati-

cally appear as the value for the channel Runtime.
Once per day, the mixer will automatically adjust itself.
The exact Time for that can be adjusted.
