Product overview
3.1
Operational area
The frequency inverter is designed for a stepless control of fans without additional (electromagnetic)
motor noise.
Temperature controller for stalls in individual or central exhaust air systems.
•
In
installations with single suction
, fans,
fl
aps and heatings are controlled via the outputs.
•
In
central exhaust installations
, these devices are used in combination. The devices controls the
exhaust air
fl
ap and the heatings for one ompartment. At the same time the exhaust air volumes of
all the compartments connected are signaled to a
Master*
. The speed is calculated from the sum
of the exhaust air volumes and the fans connected are readjusted.
In order to be able to network several devices, these are equipped with a bus interface. In this way, for
example, the supply air temperature sensor connected to the
Master*
can be communicated to all
system users. Fault messages on stall devices are transmitted and displayed as a group fault; in
addition the total exhaust air volume of the ventilation system is determined.
