You cannot download firmware,
even if you try repeatedly
Flashing red LED
When the available surplus
energy is decreased, the SSR
output with higher priority is
switched off earlier than the
relay output with lower priority
CombiWATT function runs even
if PV-plant produces power
Solid state relay (SSR) does not
switch on
Data in statistics don't
correspond with reality
Statistics suddenly erased

Check the priority settings of your loads and
connected power settings according to their
power ratings.
Check the settings in the Power offset field.
Also check the CombiWATT production limit
field, which should be low.
Load only original regulator firmware for
the WATTrouter Mx device.
Make sure that there are no problems with
the connection of the regulator to PC, or in
the PC alone (viruses etc.).
Replace the regulator or take it to repair.
Follow instructions in the LED statuses
chapter.
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 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.
Check for proper terminal connection and
observe polarity of SSR control anodes.
Always use a SSR with zero cross switch and
minimum DC control voltage of 4VDC.
Replace the regulator or take it to repair.
Replace the SSR.
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.
There was a date change in the regulator or
power failure during writing the history into
EEPROM. Statistics on SD card should be
