The condensate flows through the feed
line (1) into the ECO-DRAIN unit and
accumulates in the container (). A ca-
pacitive sensor (3) continuously registers
4
the liquid level and passes a signal to
the electronic control as soon as the
container is filled. The pilot valve (4) is
then activated and the diaphragm (5)
opens the outlet line (6) for discharging
the condensate.
When the ECO-DRAIN unit has been
emptied, the outlet line is closed again

When the microcontroller registers a
malfunction, the device will automatically
change to the alarm mode. The switching
sequence of the valve (see illustration)
continues until the fault is cleared (auto-
matically or through maintenance). The
red LED flashes as long as the device
is in the alarm mode.
Malfunctioning could be caused by, e.g.:
• Mistakes during installation
• Dropping below the necessary
minimum pressure
• Excessive condensate quantities
>
(overloading)
• Blocked/shut off outlet line
• Extreme amount of dirt particles
• Frozen piping
If the fault is not cleared within the first
minute, a fault signal is triggered (see
illustration) which can be picked off as a
potential-free signal via the alarm relay.
