9.2.3 Night reduction temperature
This menu is used to activate and set a night reduction
temperature for each defined heating system. Night
reduction means that you reduce the temperature
indoors during scheduled periods, for example at night
or when you are at work.
The value by which the temperature is reduced –
Room
temp. reduced
– can be set in the
Installer/Settings/
Heater system
menu. The factory set value is -2°C.
The options in the night reduction menu are
Off, Day by
day
or
Block
. If you select
Off
, no reduction is made at all.
Day by day menu
You use this menu to schedule a reduction on the days
of the week. This schedule is repeated every week.
The set time is the period in which the temperature is
normal. The night reduction function is activated during
the rest of the time.
Block
This menu allows you to set a reduction for a few
days during the week, for example, if you are working
elsewhere on weekdays and at home at weekends.

Reducing a heat pump’s tempera-
ture at night is a comfort setting
which generally does not reduce
energy consumption.
9.2.4 Holiday
On Monday morning at 6 am the temperature is increased
to normal; at 9 am it is reduced to the set night reduction
temperature. At 6 pm the temperature is raised again until
9pm, when the night reduction function lowers it once again.
On Sunday at 10 pm, the temperature is lowered by the set
value in the
Room temp. reduced
menu (in the
Installer/Settings
menu). On Friday at 2 pm the temperature is increased to the
set value again.
You use this option to set the number of days that you
want the set night reduction temperature to be constantly
reduced. For example, if you want to go on holiday.
You can apply this setting for up to 300 days.
The period starts from the time for which the setting has
been made.
