TOMZN support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I restore my TOMZN voltage protector to factory settings?

    For many socket models like the TOSVA-16, press the Set and Reset keys simultaneously for 2 seconds. For other DIN rail models, you may need to hold the down button for more than 12 seconds.

  • What is the default over-voltage protection setting?

    On standard voltage protectors, the default over-voltage usage limit is typically set to 260V or 270V, though this is adjustable within the device's range (e.g., 230V-300V).

  • Does the TOMZN WiFi smart switch support 5GHz WiFi?

    No, like most smart home devices, TOMZN WiFi breakers and switches typically require a 2.4GHz WiFi network for connection and configuration via the App.
