The three levels are noticeably different, but the step switch on the rear panel is used to,
First comes the highest performance level, then Medium and Low. (0-III-II-I)
Is probably the starting behavior of the engine due to save a run-capacitor!
Positives:
+ Small and compact
+ Ventilation capacity
+ Performance levels indistinguishable
+ No annoying noise >> Addendum: 29.11.2012 noise is annoying now
+ Possible wall mounting
+ Processing
Negatives:
- Prominent noise
- Only two rubber feet, with four feet
- Vibrations in unfavorable underground, only two rubber feet
- Step switch logic (0-III-II-I)
My old fan with 40 Watt, can not keep up with the Honeywell HT-900E,
Honeywell is better to two classes.
Addendum: 29.11.2012
- The fan noise has become annoying over time! The bearing of the fan shaft
is something knocked out / worn out with time / bigger game.
- Clearly perceptible hum and vibration, so annoying!
Maximum three stars!
