How to fit and setup the device
Page 60 from 66
The load is connected
correctly but cannot be
switched on
Check whether the load is fitted for
example with a thermal protection system
or a thermostat, which is currently off.
Wireless peripheral device
is off or out of the range.
Check functions of wireless peripheral
device. In case of problems with coverage
of signal, use the signal repeater. Consult
this problem with technical support.
Output LED is defect or
there is another regulator
defect
Replace the regulator or take it to repair.
Outputs do not switch on as they
should
Output is not activated
Activate the output by setting the relevant
priority.
PV-plant does not provide
sufficient power output
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.
Incorrectly set priorities or
connected power values
Check the priority setting 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 load firmware, even
if you try repeatedly
Incorrect or corrupted
*.scf file
Load only original firmware for the
WATTrouter ECO device.
Communication errors
Make sure that there are no problems with
the connection of the controller 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 SSRs with higher priority may be
disconnected earlier than the relay outputs
with lower priority.
CombiWATT software 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.
