Page 5: Operational Area
QuietAir 150 fans are used to convey normal or slightly dusty (particles size < 10 µm), little aggressive and humid air, into moderate climate and suitable area of its performance curve (see Airflow sales documentation / Internet). Operation permitted only for fixed installation within buildings. Maximum permitted medium and ambient temperature is 40ºC. -
Page 6: Motor Protection

Page 7: Chapter 4. Function
Automatic mode: The humidity control works without connecting a switch. Demand ventilation: By connecting e.g. a 2 speed switch from the Airflow range of accessories the fan can be used on different speed levels 1 and 2. The use of the switch is consistent with the functions of the fan by default. - Page 8 Occasional control (faster increase in humidity) With a rapid increase in humidity (caused possibly by showering, bathing) the fan turns on as early as possible before reaching the set threshold, to effectively eliminate excessive humidity and restore the comfort zone in the room. When reaching the set point threshold, the fan shuts down according to the timer setting.

7. Follow-up After switching off the current stage, the fan turns off after the set run time. The length of the overrun time is adjusted by the DIP switches 3 and 4 (6, 10, 15, 21 minutes). If you switch between stages, the delay time will be ignored. By simultaneous shut down of the both stages, applicable delay time can be ignored. -

Page 14: Chapter 7. Installer Function
CHAPTER 7 Function description QT150 HT (Humidity Timer Model) Exceeding the humidity threshold or ventilation on demand by switching the switch leads to activation of the fan. INSTALLER FUNCTION In case of defective humidity sensor both the automatic mode and the demand ventilation won’t work. - Page 15 3. Humidity functions Single-stage, dual-stage and infinitely variable humidity function can be chosen with a combination of dip switches 6, 7 and 8. The choice of the humidity function is technically at certain fan levels bound to the allocation of timer functions (see table below).
- Page 16 Occasional control (faster increase in humidity) With a rapid increase in humidity (causes e.g. by showering, bathing) the fan turns on as early as possible before reaching the set threshold, to eliminate effectively excessive humidity and restore the comfort zone in the room. When reaching the turn off threshold, the fan shuts down according to the timer setting.
- Page 17 9. Push-button operation When no delay start is activated (DIP switch 1 / 2 = off / off), switch inputs 1 or 2 can be controlled by an impulse button. To do so, on the relevant stage, the timer function has to be activated (DIP switch 7, DIP switch 8). The button must be pressed for more than 0.5 sec.
