What’s included
- Door sensor
- Magnet
What it is
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.
Installation, from the UKU manual
- “The door sensor kit includes a sensor, magnet, and magnet fixing tape.”
- “The length of the cable between the sensor and the main module should not exceed 32 ft.”
- “Install the sensor on the handle side of the door frame, at a maximum height of 16 in from the floor. When installed higher, the temperature may affect the performance of the magnet and the durability of the magnet tape.”
- “It is important to ensure that the door passes directly by the sensor in the door.”
- “Use a 13/64 in diameter drill when installing a door sensor recessed in the door frame.”
- “Connect the cable to terminals O1 and O2 in the main module.”
- “When closing the door, the sensor and the magnet should remain slightly displaced, and the distance between them should not exceed 13/32 in.”
Glass-front sauna rooms
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.
Checking it works
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.”

Accessories Are Great. A Sauna You Actually Use Is Better.
We stock accessories like this one so our sauna and heater customers can get everything for the room in one place. If you already have a sauna you love, welcome. If you are still planning one, or the one you have never quite gets hot enough, take a look at what we really do.

The Rabbit Hole Ends Here
Did you always have opinions about cedar? No. No you did not. Most people shopping for a sauna end up with a dozen tabs open, three brands that all say they are the best, and a forum thread that argues both ways. We have built, installed and fixed saunas like the ones we sell, and we use our own at home. Tell us about your space and we will tell you which sauna and heater fit it, and which ones don’t.
- A heater sized to your roomWe match the heater to the room’s volume, walls and glass, so it heats the way it should.
- The whole project, thought throughSpace, electrical, freight and install get talked through before you order, not discovered after.
- Still here afterThe same people answer when a question comes up mid-build, and long after delivery.
The best sauna deal is the one you don’t have to buy twice.
