Eco Saving Operation; Pm2.5 Sensor; Stopping Operation Using Off-Timer - Hitachi EP-NZG70J Instruction Manual

Eco Saving Operation

 The unit automatically stops operation when air becomes clean, saving electricity cost.
Also, if this status continues for longer than 8 hours, the unit will automatically stop operating.
Normal Auto Operation
When the air is clean, the unit will continuously operate in "Silent" airfl ow rate and not stop.
Eco Saving Operation
When the air is clean and "Silent" airfl ow rate operation continues for 10 minutes or longer, the fan stops for about
50 minutes and the unit intermittently operates using "Silent" for about 10 minutes.
If this status continues for longer than 8 hours, the unit will automatically stop operating.
* During eco saving operation, the level of air contamination is detected by the odor and dust sensors. When the
sensors detect odors and dust, the airfl ow rate will switch depending on the level of air contamination.
When the air is clean and the "Silent" airfl ow rate operation continues for 10 minutes or longer, the unit will start
intermittent operation again.

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)
Note
 Operation modes other than "Air Purify" cannot be set.
 While operating in PM2.5 sensing, the air sensor will light up, then enlarge and shrink slowly.
 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.

Stopping Operation Using Off-timer

 Set the off-timer to automatically stop the unit after the set operation time.
