• Setting the hot water buffer auxiliary heating times
:
You can change the time windows for water heating to
meet your needs:
By reducing the hot water standby time, you can
save energy.
• Setting the temperature increase
: The hot water buffer
temperature is determined from the sum of “T.WW.NOM”
and “DIFF.ON”. Auxiliary heating is started if sensor S1
(“T.ww.ACT”) in the hot water buffer is below this value.
Auxiliary heating is not switched off until the temperature
rises to “T.WW.NOM” plus “DIFF.OFF”. The factory setting
“DIFF.ON” = 9.0 K and “DIFF.OFF” = 12 K should only be
changed in exceptional circumstances. For this reason,
settings are only possible in the “Technician” operating
mode as follows.
1. Determine the days for which the time windows are
active
In
figure on right
, all days are highlighted. If you want to
enter times for workdays and weekends separately, you
must deselect the weekdays “Sa” and “Su”. Turn the
rotary wheel and jump to the day you want to change.
To deselect, briefly press the rotary wheel, turn it until
the day is no longer highlighted in black and press the
rotary wheel.
2. Enter the start and end of the time window
Use the pointer to scroll to the first time field below the
days of the week (
figure on right
) and press the rotary
wheel. Set the start of the time window by turning the
rotary wheel; the time increases in 10-minute intervals.
Press the “* 10” button on the rotary wheel while it is
being turned to switch to 100-minute intervals. Press
the rotary wheel to finish and save the entry. Continue
by entering the end time.
Repeat this procedure for setting the other time blocks
(e.g. block for “Sa” and “Su”). However, all days have
been deselected for the second time block and you
must highlight the respective days.
Use the “BACK” key to return to the function overview
menu.
