8.3.2 Outdoor Sensor/Room Sensor
Faults
If a fault occurs with an outdoor sensor, the product
triggers an alarm and an outdoor temperature of -5 °C is
simulated so that the house does not get cold.
If a fault occurs with a room sensor, the product triggers
an alarm and automatically switches to operating
according to the set curve.
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.
e.g. to activate night reduction of the temperature Mondays
00:00–06:00 and 22:00–24:00 etc.
When the clock is within the range, e.g. on a Monday at 03:00,
“NR” is displayed
The time on the left must be lower than the time on the right for
the interval to be valid.
!
When both are in use, Holiday Reduction overrides Night Reduction.
