We're reducing prices!

1.1.2024
Dear customers, we have optimized our production processes and input costs, which is why we were able to reduce the final prices compared to the 2023 price list by up to 20%! If you are our partner (installation company, wholesaler), you will find the new prices after logging into your account. On the My account page, click on the link Your current price list. If you are not our partner, the final prices listed in the Direct purchase section apply to you.

End of rationing system

1.9.2023
Dear customers, due to the availability of parts for production, we are stopping the rationing system for all products supplied by us from September 1, 2023. All products are now in sufficient quantities in stock.

Rationing system

8.1.2023
Dear customers, due to the high demand, we are introducing a rationing system for our most ordered products from 9 January 2023. For more information about this method of purchase, see here. New registrations are temporarily suspended until January 16, 2023 to allow priority purchase for our long-term business partners.

Design change

22.8.2022
Dear customers, due to better availability, from 22/08/2022 we deliver all our controllers in slightly different installation boxes, which are functionally completely identical to the original ones, only they are slightly different in design - they do not have the bottom sharp edge. The size of the controller, i.e. the number of modules and other parameters, does not change. The absence of the bottom sharp edge also objectively facilitates the installation of the controller in the switchboard.

End of cooperation with Russia

25.2.2022
Today we ended our cooperation with Russia. No orders from this country are possible and no technical support will be provided. Also, Russian language will be removed from all our future software updates.

On this page you can see a few installations of our products. There are really only few installations here. There are already many thousands of installations of our products running in Czech Republic, Slovakia, Poland and other countries.

Heating Control + WATTrouter Mx, models HC 01/06/14 a WRMx 01/08/17, family house in Plzen, CZ, 3kWp

This is our reference installation. It provides complex control of house heating, hot water preparation, pool heating and others. This house uses multi-source heating system controlled by our controllers. This system uses accumulation tank with Fujitsu outdoor heat pump unit where indoor unit is replaced by heat exchanger (condenser) in the accumulation tank. This very effective method can be used to accumulate heat from PV plant for later use with maximum effectivity and, of course, produce heat if PV power is small or none. There is detailed description of this reference, however only in Czech - see fve_tc_propojeni_wrmx_hc.pdf.

Compared to the original documentation, there have been gradual changes to this installation:

  • In 2018, the older type WATTrouter M SSR was replaced by the newer type WATTrouter Mx.
  • In 2021, 2 of our experimental SINEDRIVER® converters were put into operation on this installation for the regulation of heating cartridges in the storage tank, which replaced the original SSR RGS1A60D25KKEDIN here.
  • In 2022, a new Mitsubishi Power Inverter PUHZ-SW100YAA three-phase outdoor unit was installed, controlled by the 0-10V signal via a PAC-IF012B-E control board. This replaced the older, still functional, but less efficient and noisier Fujitsu unit.
  • In 2022, a second single-phase PV plant with a capacity of 2.2kWp was also installed, connected to phase L2.
