eta SH20 - Setting the Hot Water Charging Times

based on the set runtimes and pauses, regardless
of whether hot water is currently being drawn or
not.
Example:
Time window = 10:00 am to 2:00 pm
[Circulation runtime] = 5 minutes
[Circulation pause] = 10 minutes
=> The pump runs from 10:00 am to 10:05 am ,
then pauses until 10:15 am , restarts at 10:15 am,
pauses from 10:20 am to 10:30 am , and so on ...
until the end of the time window at 2:00 pm .
In this operating mode, the circulation pump
can also start outside of the time window
when hot water is being tapped. This is useful if, for
example, the time window ends at 8:00 pm and
you shower at 9:30 pm . When you then turn on the
hot water briefly, the circulation pump starts, and
you will have hot water for showering shortly
afterwards.
This runtime (outside the time window) is set in the
text menu (parameter [Circulation pump delay]).
Enter the same value as parameter [Circulation
runtime].

Setting the time window and copying to other

If a circulation pump is also installed (and the
function [Self-learning] is switched off), these
operating times are set in the same way (button
