Changing the Heating Curve
Example:
For outdoor temperature 5°F (-15°C):
A Underfloor heating system, slope 0.2 to 0.8
B Low temperature heating system, slope 0.8 to 1.6
C Heating system with a boiler water temperature in
excess of 167°F (75°C), slope 1.6 to 2.0

Stopping Central Heating

(continued)
Heating curves illustrate the relationship between the

outdoor temperature and the system temperature.
To put it simply: The lower the outdoor temperature,
the higher the system temperature.
The heating curves shown apply with the following
settings:
Heating curve shift = 0

A different value for shift shows a curve which is
offset in parallel to the vertical.
Standard room temperature = approx. 68°F (20°C)

In the factory set condition, the slope is set to 1.4
and the shift to 0.
