The room model calculates a fictive room temperature for rooms that have no room
temperature sensor. The value calculated for each heating circuit is indicated on these
operating lines.
This allows boost heating, quick setback and optimum start and stop control to be
implemented with no need for using a room temperature sensor.
The calculation takes into account the attenuated outside temperature (operating line
8703), the room model gradient (operating line 6112) for switching to a higher setpoint,
and the building’s time constant (operating line 6110) for switching to a lower setpoint.
