Start-up hints
With this cascade control, it is also possible to create a control type, based on room temperature with min. and max. limitation of the supply air temperature. To do so, the room temperature P-band (RMT-01) can be increased to a value of e.g. 4K, while the I-time (RMT-02) must be set to a rather high value, e.g. 3600 seconds. Now there is no fixed relation between the supply air temperature and the room temperature deviation, only the supply air temperature limits will always be effective.
