To achieve the instructed room temperature, the device applies the PI algorithm.
Attention REV <= 2.7: If a Room Temperature was provided through a Port 0x01 Downlink within the last 5 minutes, the device uses this; otherwise, it uses the estimated room temperature (internal ambient sensor).

The PI coefficients can be modified by sending a Port 0x07 Downlink.
