MENU 1.9 - ADVANCED
Menu advanced has orange text and is intended for
the advanced user. This menu has several sub-menus.
curve Setting the curve slope for heating and cooling.
external adjustment Setting the heat curve offset when
the external contact is connected.
min. flow line temp. Setting minimum permitted flow
line temperature.
room sensor settings Settings regarding the room
sensor.
cooling settings Settings for cooling.
fan return time Fan return time settings in the event
of temporary ventilation speed change.
own curve Setting own curve for heating and cooling.
point offset Setting the offset of the heating curve or
cooling curve at a specific outdoor temperature.
night cooling Setting night cooling.
MENU 1.9.1 - CURVE
heating curve
Setting range: 0 – 15
Default value: 9
cooling curve (accessory required)
Setting range: 0 – 9
Default value: 0
You can select heating or cooling in the curve menu.
The next menu (heating curve/cooling curve) shows the
heating and cooling curves for your house. The task of
the curve is to give an even indoor temperature, regard-
less of the outdoor temperature, and thereby energy
efficient operation. It is from these heat curves that the
heat pump’s control computer determines the temper-
ature of the water to the system, the supply temperat-
ure, and therefore the indoor temperature. Select the
curve and read off how the supply temperature changes
at different outdoor temperatures here. The number to
the far right of "system" displays which system you have
selected the heating curve/cooling curve for.
Caution
With underfloor heating systems, max flow
line temperature should normally be set to
between 35 and 45 °C.
With underfloor cooling, "min. flow line temp."
must be restricted to prevent condensation.
Check the max temperature for your floor with
your installer/floor supplier.
TIP
Wait 24 hours before making a new setting,
so that the room temperature has time to sta-
bilise.
If it is cold outdoors and the room temperature
is too low, increase the curve slope by one in-
crement.
If it is cold outdoors and the room temperature
is too high, lower the curve slope by one incre-
ment.
If it is warm outdoors and the room temperat-
ure is too low, increase the curve offset by one
increment.
If it is warm outdoors and the room temperat-
ure is too high, lower the curve offset by one
increment.
MENU 1.9.2 - EXTERNAL ADJUSTMENT
climate system
Setting range: -10 to +10.
Or desired room temperature if the room sensor is
installed. See illustration.
Default value: 0
Connecting an external contact, for example, a room
thermostat or a timer allows you to temporarily or peri-
odically raise or lower the room temperature while
heating. When the contact is on, the heating curve offset
is changed by the number of steps selected in the menu.
If a room sensor is installed and activated the desired
room temperature (°C) is set.
If there is more than one climate system the setting can
be made separately for each system.
MENU 1.9.3 - MIN. FLOW LINE TEMP.
heating
Setting range: 5-70 °C
Default value: 20 °C
cooling (accessory required)
Factory setting: 18 °C
In menu 1.9.3 you select heating or cooling, in the next
menu (min. supply temp.heating/cooling) set the minim-
um temperature on the supply temperature to the cli-
mate system. This means that F1345 never calculates
a temperature lower than that set here.
If there is more than one climate system the setting can
be made separately for each system.
