For the heating limit, the actual, the composite and the attenuated outside temperature
are considered.
The controller is supplied with the proportion of windows set to 50 % so that the
composite outside temperature represents the mean value of the actual and the filtered
outside temperature.
It is calculated as follows:
TOeff = (0.5 × TO) + (0.5 × TOfil)

9.5.2 Heating curve
The heating curve is defined by 2 curvepoints:
1
:
At the design temperature
• By the outside temperature TODef
A
• By the flow temperature SetPTFlDef
B
2
:
At the theoretical heating limit
• By the outside temperature TOHi
