Tips for using a water flow switch
- The ambient temperature is not lower than 0°C. Do not knock on the housing and keep away from magnetic objects.
- The output of the signal is a switch quantity, so the connection method of the control object must also be a switch control.
- The power of the controlled object shall not be greater than the signal load capacity.
- The water flow switch is a water medium control device and cannot be used for other medium control.
Builder in Product TAB
NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc.
You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules.
Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
