3.2 The principal functions
3.2.1 Acquisition of reference room or room user demand
The following elements consider the room's and its user's demand:
– Scheduler
– Room temperature
– User-defined room temperature correction (optional)
– Presence detector (optional)
– Window contact (optional)
– Manual switch for room operating mode (optional)
– Manual room operating mode (optional)
– Room temperature setpoints for heating (for the supported room operating
modes)
– Outside air temperature
- The outside temperature forecast is derived either from the actual block
based on past outside temperature measurements
- or the forecast is provided to the block from an external source.
Both valid room operating mode and associated room temperature setpoint result
from the room's and its users demands.
The reference room is important for heating circuit operation. The reference room
is the room where the room temperature used by the predictive heating controller is
measured. The reference room may not contain thermostats or other room
temperature control devices and functions.
3.2.2 Forecasting future room temperature setpoint profile
Advantages:
– Include user behavior to increase comfort
The future room temperature setpoint profile is calculated from the requirements
from the room and its users. This is done for at least 64 continuous hours. If
operation is controlled by a scheduler, the room temperature setpoint profile
contains both the present as well as upcoming setpoints.
3.2.3 Creating an outside temperature forecast
Advantages:
– Considering outside temperature forecasts enhances control quality
- The outside temperature forecast is derived either from the actual block
based on past outside temperature measurements
- or the forecast is provided to the block from an external source.
