We're reducing prices!

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

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

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

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

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.
