WATTrouter ECO - user manual
Outputs do not switch on as they
should
You cannot load 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 software runs even
if PV-plant produces power
How to fit and setup the device
The load is connected
correctly but cannot be
switched on
Wireless peripheral device
is off or out of the range.
Output LED is defect or
there is another regulator
defect
Output is not activated
PV-plant does not provide
sufficient power output
Incorrectly set priorities or
connected power values
Incorrect settings of some
items in the Other settings
tab
Incorrect or corrupted
*.scf file
Communication errors
Regulator failure/defect
The system detected error
status
This is normal
This is normal
Check whether the load is fitted for
example with a thermal protection system
or a thermostat, which is currently off.
Check functions of wireless peripheral
device. In case of problems with coverage
of signal, use the signal repeater. Consult
this problem with technical support.
Replace the regulator or take it to repair.
Activate the output by setting the relevant
priority.
Check whether there is enough surplus
energy available in respective phase wire or
sum of phases L1 + L2 + L3 is positive,
depending on configured control mode.
Check the priority setting 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 firmware for the
WATTrouter ECO device.
Make sure that there are no problems with
the connection of the controller 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 SSRs 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.
