The Outdoor Sauna Control Enclosure Set for Main Module & Controller is recommended for outdoor sauna heater installations where both the main control module and digital controller need added protection from rain, dust, humidity, and splash exposure. This complete, sauna-specific solution gives your electrician a cleaner, faster way to protect critical electronics using properly sized enclosures and IP68-rated cable glands from the start. Instead of sourcing generic boxes and improvising cable entries with silicone, this set helps create a more organized and professional installation. It includes a large enclosure for the main module, power unit, or relay box, and a compact enclosure for the controller or keypad, keeping systems like Harvia Xenio, Harvia Fenix, HUUM UKU, and Homecraft controls properly separated and protected. Both lockable IP67-rated enclosures (lock not included) support neat low-voltage cable routing, while line-voltage wiring should use electrician-supplied liquid-tight conduit and connectors. Final weather resistance depends on the proper installation of glands and fittings.
