The Parallel relay function can be used to opera-
te an allocated parallel relay alongside a selected
reference 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 o.
If the Delay option is activated, the parallel relay
will be energised after the adjusted duration has
expired. If the reference relay is switched o 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 o
and vice versa.

The mixer function can be used to adjust the actual
ow 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 dierence between the actual
value and the set value.
The mixer runtime can either be adjusted in the
channel Runtime or automatically adapted with the
Oset function. When Oset is selected, the mixer
will close rst. When button
5
is pressed, the mixer
opens and the seconds are counted in the display.
As soon as the mixer has reached its open positi-
on, press button
5
again. The time measured will
automatically appear as the value for the channel
Runtime.
Once per day, the mixer will automatically adjust its-
elf. The exact Time for that can be adjusted.
