We teamed up with FLEX to make HSA/FSA payments easier than ever.
Both systems include the control panel, main module, temperature sensor, door sensor, and installation hardware required by the package. UKU Local starts at the wall panel. UKU Wi-Fi adds the HUUM mobile app for remote start, schedules, target temperature, and status.
UKU 4.1 operates current HUUM electric heaters directly through 11 kW. Full-size HIVE 12, 15, and 18 require the UKU Extension Box. Final cable gauge comes from the heater manual, and a licensed electrician must install the control and heater.
The current manual permits qualifying control panels inside the sauna only within its location and ventilation limits. The supplied door sensor is part of the remote-start safety system. Do not omit or bypass it.
