EH-105
The supply air information states which factors form the supply air temperature
determined by the controller at the time of inspection. With room/exhaust
controlled control, the controller calculates the supply air temperature setting
according to the room temperature. With supply controlled control the supply air
temperature is kept at the supply air temperature set value. The supply air
information changes according to different AH unit running situations as follows:
