Additional specifications and description
This 5-step fan speed controller has a built-in
day-week timer. Two optimal speeds can be
selected. A day - night or day - week
control can be set via the keyboard interface and LCD
Via the input(s), the motor can be remotely
enabled or disabled. There is a normally open input and
a normally closed input available.
This fan speed controller can monitor
thermal motor contacts (TK or thermal contacts measure temperature in the motor
windings). In case of motor overheating, the TK monitoring
function will disable the motor to prevent motor damage. If
the motor is not equipped with TK contacts, both TK terminals of the
controller must be bridged to simulate normal motor temperature.
The unregulated output (230 VAC) is active
when the motor is enabled. It can be used to control an external
run-indicator, a damper, etc.
E.g. when the
fan is deactivated, the dampers is closed. When the fan is active, the damper
reset after power failure
In case of a power failure, this
controller will automatically reset itself. When the power is
restored, the motor will restart
The alarm output (230 VAC) is activated when
motor problems occur. It can be used to generate alerts.
alarm output can control a warning light.
The enclosure is made of high-quality
r-ABS plastic. This material is exceptionally heat resistant, very
tough and offers good protection against impacts. The enclosure can be
surface mounted and offers an IP54 protection
against ingress of dirt, dust and moisture.
