Fault symptom
Probable cause
Actions
Homevision® control
panel gives a warning
that the humidity in
the crawl space is too
high.
The humidity in the crawl
space exceeds the set
alarm level.
Before further action, check that the alarm
level set in the system is relevant, that the
humidity now found in the crawl space is a
problem.
Check that the air leaving the wet air hose
outlet by the foundation wall is warm and
humid, see instructions under Service and
maintenance in this manual.
Check that the wet air hose is correctly
installed and has not come loose from the
dehumidifier.
Check that the rotor in the dehumidifier
still rotates. Follow the instructions under
Service and maintenance in this manual.
Check the dry air distribution in the crawl
space, that the dry air is still freely
distributed via all nozzles in the entire
space according to the installation
description. If, for example, one of the
pipe's end plates has fallen off, the
necessary air distribution is not achieved.
Check that the ground surface in the space
is evenly covered by plastic and that any
downpipes that exit close to the crawl
space are directed away to prevent
rainwater from entering.
If the problem persists, the dehumidifier's
capacity may be insufficient for the
additional moisture and should be
swapped for a larger unit from the model
program.
Connection of control
panel failed at instal-
lation. The control unit
does not come up in
the list of available
devices that is
presented on the
control panel.
The control unit has been
powered for longer than
two minutes and is
therefore not available for
connection.
Restart the control unit by disconnecting
the current to it for a couple of minutes.
Try connecting to the control panel again.
