Odour sensor lamp
The three-colour indicators (green, yellow, red) indicate the odour level.
When the air is clean, the green lamp lights up.•
In the following case, only the green lamp lights up for the initial
1 minute. The initial level of odour is recorded as the standard
level.
1) Operation directly after attaching the front panel and UNIT1
2) Operation directly after reconnecting the power plug
If the odour level remains constant without intensifying or weakening,
the odour sensor may not detect even strong odours.
The odour sensor may not detect certain types of odours such as pet
odours other than ammonia, garlic, etc.
Even if only the green lamp lights up, you may notice some smell
because the sensitivity is different among individuals.
If bothered by odours, set airfl ow manual operation and run the unit at a
higher airfl ow rate.
