Select type of heating system,

The factory settings for the
Radiator
have a curve value (flow
temperature) of 22 °C at 20 °C an outdoor temperature, 37.4 °C at –
2.5 °C and 60 °C at -35 °C at an outdoor temperature (the high point of
the curve).
The factory settings for the
Underfloor
have a curve value (flow
temperature) of 22 °C at 20 °C outdoor temperature, 27.2 °C at -2.5°C
and 35 °C at -35 °C outdoor temperature.
At a temperature higher than 20 °C, the same curve value applies as for
20 °C.

>> Lowest permitted flow temperature T1

Set the highest and lowest permitted temperature for T1. Ensure that
the value corresponds with the selected curve and possible curve
adjustments.

Check also that the highest temperature T1 with
Underfloor
does not
exceed the permitted value for the type of floor used.
>> Heat curve
The heat curve constitutes the basis for the control unit's control of the
temperature on the heating water to the circuit and indicates how high it
needs to be in relation to the outdoor temperature. The control unit
increases the temperature of the heating water when the outdoor
temperature drops. The temperature of the heating water out to the
circuit, i.e. the flow temperature is measured by sensor T1 for circuit 1
(full name E11.T1) and sensor T1 for circuit 2 (full name E12.T1).
Each circuit is controlled by its own heat curve. The installer sets the
type of heating for each circuit, that is
Radiator
or
Underfloor
. The
curve for
Underfloor
has lower values because the floors do not tolerate
such high temperatures.
Fig. 43 Radiator
The figure indicates the factory setting curve for a radiator circuit. At -
2.5 °C the flow set point is 37.4 °C.
Fig. 44 Floor
The figure indicates the factory setting curve for an underfloor circuit. At
-2.5 °C the flow set point is 27.2 °C.

The right point of the curve (-35 °C) can be changed in
Minimum outdoor temperature
(

Chapter 16.1 ).
Set value applies for all heat curves.
A change of the right point affects the flow temperature
for all outdoor temperatures that are lower than the set
temperature.

The heat curve forms the basis for set point value
calculation of the flow temperature. Most other
temperatures for heating that are set refer to room
temperature. These values are transformed by the
control unit into flow temperature values.
