Apart from electric heater models that are equipped with manual dials for time and heating adjustments, an external control unit is required. All of our sauna heater suppliers have designed controllers for their electric heaters, some of which are also compatible with other manufacturer’s models. Whether you wish to control the sauna heater from a phone or would rather have a simple controlling system in close proximity to the sauna, there is a good deal to choose from. In this article we introduce controlling systems from HUUM, Narvi, Helo, Tulikivi and IKI to help you choose the best option for your sauna.
HUUM controllers
HUUM has a wide selection of modern controllers, all of which are compatible with other manufacturer’s electric heater models. Deciding between the HUUM control panels will depend on your electric heater model, power rating and how much flexibility you would like for setting the time and temperature of your sauna. Would you like to be able to switch the heating on from your phone when you are out and about or prefer a cost-effective and easy-to-use panel near the sauna?
HUUM has control panels and casings for a variety of tastes. The UKU Wood is a stylish panel that is best installed right outside the sauna. Image from HUUM.
All UKU controllers share similar functions. The entry- level option is UKU Local, which is made for on-the-spot-use. UKU Wi-Fi and UKU 4G can be controlled through the HUUM mobile app.
UKU Local
UKU Local is a great option if you are looking for a simple, easy-to-use controller for your sauna. It has the same features as the other UKU-range controllers, apart from mobile app compatibility. The available heating periods are 3, 8 and 12 hours.
With UKU Local, the heater is controlled from a wall-mounted panel. The panel has a minimalistic design with black, white or wood finish. The controller set includes the console, cable, main module, temperature sensor, door sensor and the sensor cable.

UKU Wi-Fi
UKU Wi-Fi controls the sauna heater through a panel and the HUUM mobile app. In order to use your phone to control and adjust the time and heating functions, there needs to be a strong Wi-Fi network around the sauna area.

You can also use the controller on the spot, without the app. The UKU Wi-Fi panel has a sleek design with the choice of a classic, glass or wood finish. HUUM have designed a surface mounting frame as an addition for the UKU Wi-Fi panel.
