General Information
!
The thermostats of the radiators
must be fully open and well
operating when the system is
tuned.
8.3.3 Night reduction temperature
You use this menu to activate and set a reduction in
the temperature at night. A night reduction means that
you reduce the temperature indoors during scheduled
periods, for example, at night or when you are working.
The value by which the temperature is reduced, Room
temp. red, is set under Installer/Settings/Radiator
system/Factory value: -2°C.
The options 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 time set is when you want the temperature to be
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.
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 increased again until 9
pm when the night reduction function reduces it again.
On Sunday at 10 pm the temperature is reduced with the value
set for Room temp. being reduced. On Friday at 2 pm the
temperature is increased to the set value again.

8.3.2 Outdoor Sensor/Room Sensor
Faults
If a fault occurs with an outdoor sensor, an outdoor
temperature of -5 °C is simulated so that the house
does not get cold. The product's alarm is triggered. If
a fault occurs with a room sensor, the EcoZenith i250
automatically switches to operating according to the set
curve. The product's alarm is triggered.
!
The time set is when you want
the temperature to be normal.
The night reduction function is
activated during the rest of the
time. Reducing a heat pump’s
temperature at night is a comfort
setting which generally does not
reduce energy consumption.
