WATTrouter Mx - user manual
a. At sunrise. Counters are reset to zero at sunrise time, which is automatically calculated by the
controller.
b. At fixed time. Counters are reset to zero at a preset time.
More information about counter reset processing is available in the chapter Description of
WATTconfig Mx items.
Note: For boilers/immersion heaters or any other hot water tanks the CombiWATT mode "does not care"
during what time of the day the water is heated and used. The CombiWATT function only supplies the
preset minimum daily power to the boiler and thus making sure that there is enough hot water when the
recommended configuration is used. In cases when even under the recommended configuration hot water
is not available in required amount, we recommend to gradually increase the daily energy limit
("CombiWATT [kWh]") for example, by 1 kWh, in order to make sure that hot water is available and at the
same time that not too much energy is consumed from public grid. This is recommended mostly for
households where consumption of hot water is high at the evening. Here it may come to the situation
where water is sufficiently heated during the present day by the PV-plant, but the next day the plant is not
capable of providing the necessary amount of energy (cloudy weather). The CombiWATT mode may also be
aided by enforcing the relevant output with a time schedule. Based on user preferences, time schedules
may even completely replace the CombiWATT mode. For more information see chapter Setting up time
schedules.
If you do not have low tariff signal available (either you don't have double tariff rate or the signal cannot be
utilized) but you still want to use the CombiWATT mode, connect the GND terminal to the LT terminal. In such
scenario, the low tariff signal will be active at all times and the CombiWATT mode will be activated after
production of PV-plant comes to an end (after sundown).

SETTING UP TIME SCHEDULES

Up to 4 independent time intervals may be set for each individual output. During these time intervals the
relevant output may be forced to be switched on, or the switching process may be prohibited (restricted). The
enforcing/restricting process may be further conditioned by the presence of the low tariff signal and / or by the
status of daily energy counters for the relevant output (field "Supplied energy") or temperature conditions.
The actual configuration of time schedules is done on the "Time schedules" tab. For more set up information,
see the chapter Description of WATTconfig Mx items, Time schedules tab.

ANDI INPUT CONFIGURATION

The controller has 4 multi-purpose ANDI inputs to connect:
1. WATTrouter-compatible external current transformers (e.g. another current sensing module or other
compatible current measuring transformers). These can measure powers exactly as ILx inputs;
2. External meters with impulse output S0, which meets the parameters specified in the technical
specification and its output signal provides information about the measured electrical energy;
3. Analog temperature sensors of NTC type;
4. Analog temperature sensors type PT1000.
ANDI inputs are not required to be used. They play an auxiliary role and provide additional information to the
controller. For more information, see chapter Description of WATTconfig Mx items, Input settings tab.
