    The cascade factor consists of the supply air controller being faster than the room controller. The cascade factor in Regio Midi acts as a divisor which affects both the P-band and I-time. Example: If the cascade factor is 3 and the room controller has a P-band of 10°C and an I- time of 300 s, the supply air controller will receive a P-band of 3°C and an I-time of 100 s.
