WATTrouter Mx - user manual
How to fit and setup the device

depending on configured control mode.
Incorrectly set priorities or
connected power values
Check the priority settings of your loads and
connected power settings according to their
power ratings.
Incorrect settings of some
items in the Other settings
tab
Check the settings in the Power offset field.
Also check the CombiWATT production limit
field, which should be low.
You cannot download firmware,
even if you try repeatedly
Incorrect or corrupted
*.scf file
Load only original regulator firmware for
the WATTrouter Mx device.
Communication errors
Make sure that there are no problems with
the connection of the regulator to PC, or in
the PC alone (viruses etc.).
Regulator failure/defect
Replace the regulator or take it to repair.
Flashing red LED
The system detected error
status
Follow instructions in the LED statuses
chapter.
When the available surplus
energy is decreased, the SSR
output with higher priority is
switched off earlier than the
relay output with lower priority
This is normal
Relay outputs have always longer delay
when in the process of disconnecting. In
order to make sure that energy from the
power grid is not drawn unnecessarily, all
connected proportional outputs with higher
priority may be disconnected earlier than
the relay outputs with lower priority.
CombiWATT function runs even
if PV-plant produces power
This is normal
CombiWATT will be initiated even if during
the time specified in the CombiWATT delay
time field, no production is detected at any
phase wire, which may occur if the PV-plant
produces small amount of energy or if loads
with large power consumption operate for
long time and consume all available surplus
energy. If you want to eliminate this
behavior, increase the value in the
CombiWATT delay time field.
Solid state relay (SSR) does not
switch on
SSR is not connected
correctly
Check for proper terminal connection and
observe polarity of SSR control anodes.
Incompatible relay
Always use a SSR with zero cross switch and
minimum DC control voltage of 4VDC.
Regulator failure/defect
Replace the regulator or take it to repair.
SSR failure/defect
Replace the SSR.
Data in statistics don't
correspond with reality
This is normal
The data are indicative only; the device
does not have accurate data from
utility/billing meters. Furthermore, the
device may be configured improperly, i.e.
does not evaluate the same as your utility
meter does.
Statistics suddenly erased
This is normal
There was a date change in the regulator or
power failure during writing the history into
EEPROM. Statistics on SD card should be
