6.1.1 Type of building (“damping” of outdoor temperature)
A building's heat storage capacity and its characteristic resistance to heat transfer will delay the
effect of outdoor temperature variation on the rooms inside. As a consequence, it is not the current
outdoor temperature that is crucial to the heat demand of rooms, but the so-called “adjusted outdoor
temperature”.
The building type parameter can be used to set the level of delay with which variations in outdoor
temperature are registered. This allows the heating system control adapt to the characteristic
behavior of the building.
The controlls calculates the time constant for the delay in response to the outdoor temperature

Parameter:
building type Type of construction
light Buildings with small heat storage capacity and low to medium levels of
insulation, e.g. 2x4 wood frame or prefabricated construction with typical
insulation.
medium Buildings with medium heat storage capacity and high levels of insulation,
e.g. 2x6 wood frame or cinder block construction with above average insulation
(factory default).
heavy Massive buildings with high heat storage capacity and high levels of insulation,
e.g. poured concrete, heavy brick or heavy cinder block construction with
excellent insulation.
