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.

Price increase

1.2.2022

Dear customers, business partners,
Due to the ever-increasing prices of all input components and energies, we are also forced to increase the prices of our products and accessories that we offer. Price increase 1.2.2022
As part of the adjustment of our price lists, on the other hand, there was a slight reduction in software extensions.
You can find the new prices in our e-shop.
Thank you for your understanding.

Global semiconductor shortages

18.10.2021

Dear customers, due to these shortages we are not able to produce many of our products, especially wattrouters. The problem might affect even our other products, please refer here for further info and expected lead times.

Updates for Heating Control

USB interface driver

https://ftdichip.com/drivers/vcp-drivers/

Note: Please in case of communication problems always upgrade this driver to the newest version!

Regulator firmware and software HC downloader

The HC downloader software runs on Windows 7 and later. Since version 2.0 we provide only 64-bit versions of the HC downloader software, up to version 1.0 they are 32-bit.

Please always update BOTH software and firmware for your device!

Newest version (May 2023):
Added: The button Manually refill pool (Pools tab).
Modified: Optimized web interface for shorter loading time and smaller FLASH footprint. Most images were replaced by CSS styles or SVG drawings.
Modified: Vendor identifier of the MAC address (first 3 bytes) made read only.
Fixed: Some problems in pool filling.
Fixed: Tank cool down into pool (Pools tab). Cool down could start during pool water temperature check, which is considered to be a bug.
Fixed: Behavior of the mixing valve (Heating circuits tab). In thermal control mode, circulation pump did not run at 100% when mixing valve was in motion or some time afterwards.
Fixed: Behavior of the mixing valve (Heating circuits tab). The incremental controller did not run well for mixing valves with shorter slew times than 240s.
