CONFIGURATION EXAMPLES
These examples only demonstrate the potential use of the device - in most cases however, settings must be
modified. The examples were created in version 1.0 of the software. In newer versions there may be other
advanced options to further increase the efficiency of the system.
EXAMPLE NO. 1 – ONE LOAD ONLY
Boiler with nominal power rating of 2 kW, 200l of water, average cold water temperature at the input is 12 °C,
hot water target temperature 50 °C, average daily water consumption is 160 l. The daily amount of electric
power necessary to heat up the entire boiler (without taking into account heat losses) is:

Average daily losses of boilers with these parameters represent approximately 1.5 kWh. If you use 160 l of hot
water and you take into account heat losses, the daily supply of electric power is approximately 8.6 kWh.
Boiler is connected to SSR output No. 1, WATTrouter device uses low tariff signal and the boiler operates under
CombiWATT mode.
With the ”Each phase separately”-control mode set, in this configuration with one appliance connected to L1
we cannot use surpluses in phases L2 and L3. In the ”Sum of all phases”-control mode, it is irrelevant to which
phase wire the boiler is connected and the Phase fields cannot be changed. The ”Sum of all phases”-control
mode is better, but your 4-quadrant meter must allow it.
