5.1.4 Days away from home scheduling
Menu
¬
Days away from home scheduling ¬ HEATING
1 and, if relevant, HEATING 2
With this function, you can set a period with a start and
end date and a temperature for days during which you
are away from home. Thus, you do not need to change
periods for which you have set, for example, no reduc-
tion of the desired temperature over the course of the
day.
Hot water production and circulation are switched off
and frost protection is activated.
While the "Days away from home scheduling" function is
activated it has priority over the set operating mode. At
the end of the specified period, or if you cancel the func-
tion, the heating system returns to the pre-set mode.
i
"HEATING 2" is only shown under "Days
away from home scheduling" if a mixer mod-
ule VR 61/2 is connected. "HEATING 2" has
the same read options and settings as
"HEATING 1".
5.1.5 Days at home scheduling
Menu ¬ Days at home scheduling ¬ HEATING 1 and, if
relevant, HEATING 2
With this function, you set the desired "Day" tempera-
ture for days which you spend at home. This means you
do not need to change the periods which you have
already set, for example, with an decrease in the desired
temperature during the day.
Within the specified period, the heating system works in
"Automatic mode" and uses the day settings for "Sun-
day", which were set using the "Time programmes"
function.
At the end of the specified period, or if you cancel the
function, the heating system returns to the pre-set
mode.
i
"HEATING 2" is only shown under "Days at
home scheduling" if a mixer module VR 61/2
is connected. "HEATING 2" has the same read
options and settings as "HEATING 1".
