Built for these

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.”

PLAN THE WHOLE SAUNA

The room and heater still have to work as one system.

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.
