provider or use the "each phase independently"-mode, which works for any configuration of the
energy meter.
In order to use the "each phase independently"-mode, it is necessary to select correct phase for each
output, i.e. phase where the corresponding load is really connected. Controller will then try to
maintain zero energy flow in each phase ("phase zero"). You may check correct phase assignment
again through the TEST button. Within a short time after pressing the button the active power drawn
by connected load must be detected by the current sensing module on relevant phase.
As far as your energy meter is configured to evaluate sum of powers in all phases, you may use the
mode "sum of all phases". Here the controller will try to maintain virtual zero energy flow. This means
that for output switching it takes the sum of measured powers from all 3 phases ("virtual zero"). Here
you may try experimenting with both methods, but it is recommended to use "sum of all phases"-
mode, because it is more effective for the user.

After a correct setup of the control mode, you may start to assign priorities and power ratings for
individual outputs. This can be done on the "Output settings" tab. Select priorities of individual loads.
The switching process based on priorities may be described as follows:
By default (during night), all loads are turned off. If PV-plant production (available surplus energy) is
determined in the morning, the output with the first (highest) priority is switched on. The switching
time is different for proportional outputs (their function equals to proportional or PWM) and relay
outputs. Proportional outputs are switched on almost immediately (this is the proportional switching),
but relay outputs are switched on only if the available surplus energy exceeds the value specified in
the Connected power field (there is also a different solution available – see the "Prepend before
triacs/SSRs" function). When the load is switched on (for proportional output it means the load is
switched to the value specified in the Maximum power field), the system waits until the power output
of PV-plant increases again (sunrise). If additional available surplus energy is determined when the
load with first priority is switched on, then load with second priority is switched on in the same mode.
The same applies to all outputs. If the available surplus energy decreases, or if another load in the
household is switched on, active outputs are disconnected according to preset priorities but in reverse
order (first, the load with the lowest priority gets disconnected).
The value in the "Connected power" field should be equal to the power rating of the connected load.
For relay output it must be higher or equal to the power rating of the load, otherwise the controller
will not operate correctly, and the load will be repeatedly turned on and off. For proportional output
this value only configures the control dynamics, but it should be also equal to the actual power rating
of the load.
The fields On-delay time and Off-delay time for relay outputs specify the time delay to switch the relay
on or off after a condition has been detected to do so. This feature is necessary for loads which cannot
be switched on frequently.
Set outputs according to the connected loads and based on your priorities and then press the Write
button. The configuration will be saved in the controller. Now the main function of the controller
should be configured.
11.
Test the main function of the controller, or possibly, modify priorities for outputs and power settings
of connected loads.
SETTING UP COMBIWATT MODE
After you have successfully tested the main function, you may start to configure CombiWATT mode, provided a
low tariff signal is connected to the controller (it may be used even if single tariff rate is present – see notes
