CONFIGURATION EXAMPLES
The examples below only illustrate the possible use of the device; in most cases it may be necessary to adjust
the settings. The examples were created in version 1.1 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,
warm 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
warm 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 ECO device uses low tariff signal and the boiler operates
under CombiWATT mode.
