Operating In Pm2.5 Sensor; Switching Temperature / Humidity Monitor Display; Stopping Operation Using Timer - Hitachi EP-A9000 Instruction Manual

Useful Features

Operating in PM2.5 Sensor

 Change into a sensor that is suitable for small particles, like PM2.5 (general term for micro particles be-
low 2.5µm). The level of contamination in the air will be detected by the dust sensor, and the unit will op-
erate automatically between "Medium" to "Max" airfl ow rate.
(Odor sensor control will not be performed)

 For the fi rst 90 seconds of operation, the unit will operate in "Max" airfl ow rate (air sensor: red).
 The fl ap direction will be diagonal.
 It will not respond to the switching of sensor sensitivity.
