Overview

The HUUM UKU Extension Box is required any time a larger HUUM electric sauna heater is paired with a UKU control. When your heater output is above about twelve kilowatts the extension box expands the switching capacity of the system so the UKU control can safely manage the higher power load while keeping wiring clean and organized.

Features

  • Required for HUUM electric sauna heaters over roughly twelve kilowatts when used with UKU controls

 

  • Compatible with HUUM UKU Local and HUUM UKU Wi Fi control systems

 

  • Dedicated enclosure keeps high power connections away from the user interface

 

  • Wall mounted housing sized to install near the heater or main control module

 

  • Helps the UKU system handle higher current draw on large heaters

 

  • Ships with installation and operation manual from HUUM
