>> Minimum outdoor temperature
B Set the minimum outdoor temperature for the heat
curve.
> Circuit 1 Heating
>> External set point value
B Change to Yes if an external signal 0-10V should
control the flow temperature (fixed set point value).
1V= 10 °C, 10V = 80 °C (linear function).
>> Type of heating system
B Select type of heating system, Radiator or
Underfloor.
The factory settings for the Radiator have a curve value
(flow line 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.
>> Highest permitted flow temperature T1
1)
The value that is set in Lowest permitted flow
temperature T1.
>> Lowest permitted flow temperature T1
B Set the highest and lowest permitted temperature for
T1. Ensure that the value corresponds with the
selected curve and possible curve adjustments.
B 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).

The right point of the curve (-10 °C) can be
changed in Minimum outdoor temperature
(ÆChapter 15.1). The set value applies to all
heat curves.
A change of the right point affects the flow
temperature for all outdoor temperatures
that are lower than the set temperature.

Tab. 50 Underfloor
The heat curve forms the basis for set point
value calculation of the flow line
temperature. Most other temperatures for
heating that are set refer to room
temperature. These values are transformed
by the control unit into flow values.
