Function description QuietAir QT150 VS
QuietAir QT150 VS can be continuously operated by e.g. connecting a 3 Amp-
Stepless Speed Controller (accessory) or 0-10 V set point generator.
The control board is on terminal 7 where a potentiometer supply of +10 V is
available. Alternatively, a set point can be set via an external control voltage of the
category "SELV" safety extra-low voltage at the terminals 5 (GND) and 6 (+ 0-10V).
If the Control voltage <0.5 VDC, the fan will completely switch off.
1. Terminal assignment
- Terminal N / L
Terminal N and L have to be connected to the 230V operating voltage.
- Terminal 5
Terminal 1 activates the low stage.
- Terminal 6
Terminal 2 activates the high stage.
- Terminal 7
+10 VDC
- Terminal 3, 4
The last specification conducts independently with or without timer.
By simultaneous operation of two stages - conducts stage 2.
A change of the DIP switch settings must be carried out only by authorized
and qualified electricians. The device must be disconnected (all-pole) from
power supply. A change of the DIP switch is allowed only after switching off
mains supply.
2. Activation of the timer function
Timer function (turn-on delay, post-run time) can be activated at the requested stage
or deactivated via 7 and 8 DIP switches.
