1.5.8 Temperature control
The set temperature may be:
- the return air temperature
- the room temperature
- the supply air temperature
Two temperature control schemes are available:
- "Precision" mode, where a low deviation from the reference temperature is requested.
- "Energy optimisation" mode, where the key factor is the cost of energy.
"Precision" mode:
In this case, the regulated temperature is the room or return air temperature and the difference between this temperature and the
setpoint enables the setpoint used as the basis for controlling the supply air temperature to be calculated
