Time switch program for d.h.w. heating

•
D.h.w. is heated only if required.
•
The user can set the d.h.w. heating times to suit his lifestyle.
•
Energy can be saved by making adequate use of the time switch program
The time switch program for d.h.w. consists of the switching times to be entered for the
weekdays or the 7-day block.
The time switch program for d.h.w. and the time switch program for space heating
operate independently of one another.
The time switch program is active only when, on operating line 121 (d.h.w. program),
setting 2 has been selected.

This setting must be made before the switching times are entered!
•
For every day on which other switching times shall apply, the preselection of the
individual day with subsequent entry of the switching times must be repeated
This setting is used to select either the whole week (1-7) or individual days (1...7).
Entry:
1-7 7-day block: Entry of the switching times on lines 30 to 35 is identical for every
day from Monday through Sunday
1...7 Individual days: Entry of the switching times on lines 30 to 35 is made only for
the individual day selected here
The principle is the same as that used with "Time switch program space heating" (refer
to the diagrams and tips on page 39).
