10.7.1 Type of optimization
The type of optimization decides whether the optimization functions and boost heating
shall be performed based on the acquired room temperature or whether the room
model shall be used.
In plant where the heating circuit operates in connection with a ventilation system as a
room control combination, the room temperature sensor of the ventilation plant must
not be located in the extract air!
Based on the outside temperature, the building time constant and the rate of room
temperature increase, the room model calculates the room temperature.
If no room temperature sensor is connected, the optimization functions can work with
this room model.

In the case of sudden positive increases of the room temperature setpoint, the room
model temperature is updated at the rate of room temperature increase. In the case of
sudden negative drops, the room model temperature approaches the composite outside
temperature at 3 times the building time constant, whereby the process is stopped as
soon as the current room temperature setpoint is reached.
