The SENSOR-75 variation is the long-run cable for the temperature/door-sensor circuit. See the full product and build your package →
For use with HUUM UKU controls. The door sensor consists of two parts: a sensor and a magnet. This will help with energy costs by not heating the room when the door is open.
It is not an optional extra. Our UKU control listing states plainly that the supplied door sensor is part of the remote-start safety system and should not be omitted or bypassed.
Where the front of the room is a full glass door in a metal jamb, tucking the sensor in near the floor and running it through the jamb can be difficult. A practical alternative is the first-tier bench, below the hinge cover, as an easier location.
The manual’s test: close the door, start heating, then open the door. “The relays should disconnect within 5-10 seconds and the message ‘Door open’ appears on the screen. Close the door. The relays activate again, the message disappears and heating continues.”

PLAN THE WHOLE SAUNA
Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
See electric sauna heaters by output, stone mass, control style, and installation type. Size from adjusted room volume, not floor dimensions alone.
