Digital inputs can be used to
force the unit to start or increase
to Normal running although the
timer says the running mode
should be
Off
or
Reduced
If the running time is set to 0
the unit only runs as long as the
digital input is closed.
The time the extended running
is active is monitored in “Time in
ext. Running”,
It’s also possible to set here as
well in order to shorten the initial
set period.
