Operate aggregates per time switch 2
When your controller is configured with a time switch, the
controlled aggregate (e.g. a pump) is switched on and off
per the set time switch program.
If also configured with
[Time switch 2] op selector
, it must be
set to
auto
, to automatically switch on and off the aggregate
per the set time switch program.
If a
[time switch 2] op selector
is available and you do not want
to control the aggregate per the time switch program, you
can manually override it with the
[time switch 2] op selector
either
on
or
off
.

Time switch 2
Saturday
Switched on at 6:00 am – switched off at 10:00 pm
Path:
Welcome > Main menu > [Time switch 2] op selector > Preselection:
If you want to set the plant to
On
or
Off
for a limited period only, do not forget to return to
auto
in due time!
