IoT (Internet of Things) => Devices with SRE connect control can be remotely controlled
and monitored with any internet-enabled computer, mobile phone or tablet.
For power regulation, the negative pressure unit is supplied with a control via a touch
display to measure and regulate the negative pressure and / or the volume flow.
The negative pressure is measured between the black area and a reference point to be
defined (adjacent rooms) and kept at the setpoint value by continuous speed control of
the electric fan.
The volume flow is measured in the device and kept at the setpoint value by continuous
speed control of the electric fan.
A manual control is also possible.
A filter sensor monitors the particle concentration in the exhaust air and triggers a visual
and audible alarm if a value of 100 particles per liter is permanently exceeded.
A necessary filter change is shown on the display.
