The current room temperature in this frame (bytes S8 and S9, RC_L and RC_H) is unreliable and should not be used! Instead, use the data from the frame (qq=30h, zz=26h, pb=B5h, sb=05h, nn=05h, first data byte 3Ch). Also note that the byte S6 has been found to be missing if the target room temperature is set to 22.0°C. It is unclear whether this is intentional or a bug.
