6.1.1 Building type (adjusting the outside temperature)
A building's heat storage capacity and its characteristic resistance to heat transfer will delay the
effect of outside temperature fluctuations on the rooms inside. Consequently, it is not the current
outside temperature that is crucial but the so-called adjusted outside temperature. Parameter
building type enables the adjustment to be applied that takes account of the fluctuating outside
temperatures. This enables the control to be matched to the characteristics of the building.
The control unit calculates the time constant for adjusting the outside temperature, using the factor
given in Tab. 11 for the stated building type and an internal multiplier, the "runtime" (= 6 minutes).
The time constant is the product of: factor x runtime = adjustment time constant in hours.
Should the adjusting of the
outside temperature be switched
off?
Yes, No No When selecting “yes” the following
parameter building type will be
hidden.
What type of building do you
have?
Light,
medium,
heavy
Medium Building type (heat storage capacity),
