B 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.
> 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 settings are the same as for Circuit 1.
> Room sensor
The settings are the same as for Circuit 1.
> Room temperature program
The settings are the same as for Circuit 1, except that
Copy to all heating circuits is not included.
> Regulator settings
The mixing valve is controlled with PID regulator in order
to reach the flow set point value when there is a need.
The signal determines how much the opening of the
mixing valve should change. It is calculated with short
time intervals.

The right point of the curve (-35 °C) can be
changed in Minimum outdoor temperature
( Chapter 16.1.1). 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.
