1.1 Warnings
The adjacent symbols are safety warnings. To avoid any risk of
injury and dangerous situations, all safety regulations (symbols)
in this document should be strictly observed.

550
For all work involving operation of the fan, general applicable
safety and accident prevention regulations should be observed.
All electrical work and commissioning should be carried out
by authorized and qualified electricians.
Maintenance and installation work should be carried out by
competent personnel.
Before cleaning, maintenance and installation work or before
opening the terminal compartment the following points must
be observed:
- Disconnect the fan from power supply (all-poles) and secure
against restarting!
- Wait until all rotating parts have stopped moving!
- After rotating parts have stopped moving, waiting period of 3
min should be observed; dangerous voltages can occur by
internal capacitors even after disconnection from the network!
All equipment-related safety regulations should be observed!
If necessary, further country-specific regulations should be
complied with!
Contact protection (or Protection against accidental contact)
should be insured according to DIN EN 13857 (see Chapter
2.1)!
Contact with rotating parts should be avoided.

Ensure a uniform inflow and free outlet!
During operation within a fire place in the ventilated room,
sufficient air supply should be provided in all operating
conditions (please contact chimney sweep).
Valid local regulations and laws should be observed!
The QT150 HT fan should not to be used by children and
persons with reduced physical, mental or sensory capacities,
without proper practical experience or expertise, unless they
are controlled or instructed on the product operation by the
person(s) responsible for their safety. Children should not
play with the device. Cleaning and maintenance must not be
carried out by children without supervision.

FUNCTION

Function description
All of the following information and instructions are intended for use by
authorized electricians. All times may vary slightly due to component
tolerances and ambient temperatures.
Exceed of the humidity threshold or demand ventilation caused by switching
the switch will lead to the turning on of the fan. The required ventilation is
superior to the humidity control.

Background
There is a humidity decrease (reduction) during the fan operation. The
reduction however hasn’t been enough to fall below the turn off threshold. Short stop
time activated since it can be assumed that after a short break the humidity can still
be effectively reduced.

Electrical installation/Commissioning
Safety instructions listed in Chapter 1.2 should be observed
!
All electrical installations to be carried out by an approved electrician
in accordance with presented manual and wiring diagrams.
!
The relevant standards, safety regulations (for instance DIN VDE 0100)
and technical connection regulations of the energy supply company
should be observed!
!
An all-pole mains switch/isolation switch, with at least a 3 mm contact
opening (VDE 0700 T1 7.12.2 / EN 60335-1) is mandatory by law!
!
Network configuration, voltage and frequency of the power source
should match the information on the rating plate.

Any changes of the DIP switch or potentiometer 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.
All timer settings may vary slightly due to component tolerances and ambient
air temperatures.
