Weekly switching programme for domestic4.11 water
The weekly switching programme repeats itself every week. It consists
of a maximum of 48 switching commands. The switching commands
are captive. There are three possible operating statuses for domestic
water heating, with the following symbols:
STOP no domestic water heating
START normal temperature for domestic water
START increased temperature for domestic water
Notes on the weekly switching programme:
A switching command can be valid daily (1-7) or on a particular day•
(Mon, Tue, etc.).
If there is a switching command on a particular day of the week•
(Mon, Tue, etc.), the daily switching command (1-7) is not valid on
that day.
If you want domestic water heating to operate always in normal•
mode, there must be at least one switching command that invokes
the normal domestic water temperature.
