11.4 Room temp.
This is used to set the desired room temperature. Use
the plus and minus buttons to set the temperature you
want. The “setpoint” temperature is given in brackets.
You can see the current value next to the brackets.
If two heating circuits are installed, the values for both
are displayed here.
If you want to schedule a temperature reduction,
you can continue to the Night reduction or Holiday
submenus.
Room sensor is defined in the Installer/Define system/
Heating circuit menu. Select “Room sensor No” if the
room sensor is poorly positioned, if the floor heating
system has separate room sensors or if you use a fire
place or open stove. The alarm LED on the room sensor
still functions as normal.
If you use the fire or open stove only occasionally, the
firing process can affect the room sensor and reduce
the temperature supplied to the radiators. It can then
get cold in the rooms in other parts of the house. The
room sensor can temporarily be deselected during the
firing process. The heat pump then provides heating to
the radiators using the set heating curve. The radiator
thermostats reduce the heating supplied to the section
of the house where a fire is burning.
11.4.1 Setting without a room
sensor
If a room sensor has not been installed (selected in
the Settings menu), you adjust the room temperature
using this option, which displays the setting range as
a percentage. If this range is not sufficient, the default
setting must be adjusted under the Installer/Settings/
Heating circuit menu.
Change the value in small steps each time (approx. 2
to 3 steps) and wait for the result (approx. one day), as
there is a delay in the system responding.
Several adjustments may be necessary at different
outdoor temperatures, but you will gradually achieve the
right setting that will not need to be changed.
11.4.2 Outdoor sensor/room
sensor errors
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 heat pump
automatically switches to operating according to the set
curve. The product’s alarm is triggered.
i
The radiator thermostats must
always be fully open and operating
correctly when the system is tuned.
The example above shows that the room temperature is 22.4
°C, but the desired value (setpoint) is 23.5 °C.
The example above shows operating with two heating circuits.
Heating circuit 1 with a room sensor and heating circuit 2
without one.
