DHW and ventilation program
In parameter DHW VENTILATION PROG,
you can adjust the times for the day and
setback temperatures for DHW heating or the
Ventilation program.
You can adjust the DHW heating or ventilation
as follows:
– for every day of the week
(Monday, ..., Sunday)
– Monday to Friday (Mo - Fr)
– Saturday and Sunday (Sa - Su)
– the whole week (Mo - Su)
You can adjust three switching time pairs
(I, II, III) for each of these options.
Exception: You will need two switching time
pairs, if you want to define a program from
22:00 h until 06:00 h the following day.
Thereby you determine how often, during
day and setback mode, the ventilation device
should provide DHW and when the ventilation
should run in either day or setback mode. You
will already have selected the corresponding
set values for day and setback mode under the
system parameter DHW TEMP.
Example:
You want to heat up DHW daily at two
different times, i.e. from 22:00 h until 06:00 h
the following day, and then again from
08:00 h until 09:00 h.
The day begins at 00:00 h; therefore begin
programming for this example at 00:00 h. The
first switching times pair runs from
00:00 h until 06:00 h. The second switching
times pair runs from 08:00 h until 09:00 h. The
third switching times pair runs from 22:00 h
until 24:00 h.
