◄How to choose a sauna controller for an electric sauna heater?

Choosing UKU Controller UKU Local UKU Wi-Fi UKU GSM All three controllers share the same basic functions and design. The main difference between them is that UKU Local is made for only on-the-spot use while UKU Wi-Fi and UKU GSM can additionally be controlled through HUUM mobile app. Continue reading and discover more in detail what these sauna controllers can do and which kind of saunas are they suited for.

Main Features of UKU Sauna Controllers Let’s first take a look at the features that all three UKU controllers have in common. They are suitable for any manufacturer’s electric sauna heater as long as it works with a controller, has a temperature control function and its output does not exceed 18 kW. You can choose a target temperature between 40-110 °C. You can choose a heating period of 3, 8 or 12 hours. A timer function allows you to select a starting time for heating. For example, if you would like the sauna to be hot when you arrive home from work, you could just set the timer before you leave home in the morning. This way a hot sauna will be waiting for you when you get back. UKU sauna controllers can be connected to the lights/ventilation and steamer functions of the sauna, allowing you to control all of them from the same remote control. Safety features include overheating protection, door sensor and child safety lock. Overheating protection stops the heating when the temperature in the sauna gets too high. This happens around 140°C. Thanks to the door sensor, your remote control will not start heating if the sauna room door is open. The child safety lock prevents little children from activating the sauna heater. All HUUM sauna controllers have an elegant and minimal design and they are easy to use. Just one button gets everything done and gives the remote control an overall clean look. Whichever model you prefer, you can choose a case that best suits your taste and the interior of your sauna. UKU controllers come in wooden and different colored plastic cases. Wooden cases are handmade out of thermo-treated ash. Plastic cases come in the following colors: black, white, grey, blue and sand.

Local vs. mobile app sauna controllers When it comes to choosing between the three sauna controller models, the most important question is whether you wish to control your sauna only through the controller or would you like to control it also using a mobile app. If you are interested in on-the-spot use only, then UKU Local might be the right choice. In case you would like to explore the possibilities of mobile app remote control, read more about UKU Wi-Fi and UKU GSM controllers. Using the mobile app to heat your sauna can help you save time, organize your day better and find more moments for relaxing in the sauna. You could be anywhere and still have your sauna hot and ready by the time you want. All it takes is a few taps on your phone. UKU Wi-Fi and UKU GSM differ from each other in the way they connect to the network. Below we’ll go further into details about the differences of the sauna controllers.

UKU Local – local sauna controller As we already mentioned above, UKU Local is a good option for your sauna if you prefer heating it from the controller on the wall. It has all the features in common with UKU Wi-Fi and UKU GSM, the only exception being that you can’t control it through the mobile app.

UKU Wi-Fi – sauna controller with a mobile app UKU Wi-Fi can be used as a regular sauna controller on the wall. Additionally, you can connect it to HUUM mobile app on your phone and heat your sauna through the app. In order for the controller to be able to communicate with the app, it needs to be connected to a Wi-Fi network. For this reason, it is suitable for places where there is already a wi-fi network, like homes, accommodation establishments, offices, etc. UKU Wi-Fi is unique among Wi-Fi sauna controllers for two reasons. Firstly, your phone doesn’t have to be connected to the same Wi-Fi network of the sauna to use the app. You can be anywhere and still start heating your sauna. The second great advantage is that you don’t need to connect the controller to the Wi-Fi router with cables or anything. It connects to the network in the same way as your phone or your computer. All you need to do is choose the right network and insert the password.

UKU GSM – sauna controller with a mobile app Just like UKU Wi-Fi, UKU GSM can be controlled from the remote control or using HUUM mobile app. The advantage of UKU GSM is that it does not need Wi-Fi to connect to the app. It comes with a SIM-card and uses mobile data. So, all you need is a mobile data reception in the place where you install your controller. UKU GSM is a good solution if you wish to heat the sauna using your phone but your sauna doesn’t have a Wi-Fi connection or it is not convenient to set it up. It is suitable, for example, for holiday homes that are not in use all year round, saunas that are distant from houses and mobile saunas that are moved around. Since UKU GSM works with mobile data, there is a small additional cost to using the app. Using HUUM app with UKU GSM is free for the first year and costs 29 €/year thereafter. The annual fee includes mobile application features, mobile data, secure server, unlimited app users, application and remote control software updates. The remote control can always be used also without the mobile app.

Conclusion Choosing between the three sauna controller models comes down to whether you wish to heat your sauna only from the remote control or would you also like to do it independently of your location using HUUM mobile app. Choose UKU Local if you simply want to use the remote control on the wall and you are not interested in heating your sauna from a distance. If you would like to be able to heat your sauna also through the mobile app, choose UKU Wi-Fi or UKU GSM. UKU Wi-Fi is suitable for saunas that are already in the Wi-Fi range. UKU GSM works also if you don’t have Wi-Fi in your sauna. You just need a mobile data reception.

Save Time with HUUM Mobile A HUUM sauna controller with the mobile app remote control option has two important advantages. Firstly, it saves you a lot of time. Let’s say heating the sauna takes about an hour. With a regular sauna controller, it would mean that once you arrive home you would still have to wait an hour before you can actually use it. With a mobile app remote control, you can start heating the sauna even without being home yet. You can just activate the sauna heater from your phone and spend that hour finishing up at work or exercising at the gym. In moments when you need a hot sauna the most, you don’t have to wait for it. Maybe you have just spent an entire day skiing or you’re on your way back from a long trip. What could be more welcoming and regenerating than a hot sauna waiting for you the moment you step through the door. We asked our customers how is the mobile app working for them and how are they using it. Harry from Finland wrote us this: “Yes, I use the HUUM app frequently, in fact, I always switch the sauna on with the app, whether I am at home or not. When I’m sitting on the sofa – yes, why not switch the sauna on from the phone? When I’m in the garden – there’s no need to go inside the house, I just switch it on while I’m outside. When I’m shopping in the city center, working late at the office or walking outside with my dog – why not switch the sauna on to have it ready by the time I’m back home? It’s simple and easy.” Another useful aspect is that you don’t have to be physically present to heat the sauna. Here lies a great opportunity for the owners of Airbnb apartments, guesthouses and other accommodation establishments looking to offer something special to their guests. Adam Rang from Estonian Saunas is already using this smart sauna solution with his Airbnb guests in Tallinn. He provides his guests with sauna log-in information before their journey there. This way the guests can activate the sauna heater accordingly to their travel schedule and have a hot sauna waiting for them on their arrival. Also, during their stay in Tallinn, they can always set the sauna to a perfect temperature for their return to the apartment after having spent an entire day exploring the city.

HUUM Mobile App Works with UKU Wi-Fi and UKU GSM Sauna Controllers If you would like to heat your sauna with the HUUM app you first need to purchase a sauna controller with that feature. So, you should have either UKU Wi-Fi or UKU GSM controller installed in your sauna.

Once the controller is in place, all you need to do is download the HUUM app into your phone and connect it to your controller. To do that, just follow the instructions on the screen and insert your sauna controller’s ID and code when requested. After that, you are ready to heat your sauna from the app and enjoy all its features.

Prepare Your Sauna Experience With a Few Taps on The Phone HUUM mobile app is about more than just switching the sauna heater on and off. It provides several useful features for adjusting your sauna experience to your wishes. First, let’s go over the basic functions. When it comes to heating, you can choose the beginning and end time of the heating and set the desired temperature. Thanks to the door sensor of the UKU control unit, the app will know if you have left your sauna room door open and will not allow heating in that case. While the sauna is heating, you can check the current temperature at any moment to see how it’s proceeding. If you already know exactly what time you need your sauna to be hot, the timer function comes in handy. Just activate the timer and have the sauna heated exactly by the time you arrive home from a workout or in time for a sauna party. HUUM sauna controllers can be connected to the lights, ventilation and steamer functions which can be controlled through the mobile app as well. In order to do that you must first activate these functions from the control panel on the wall. The number of app users is unlimited.

Frequently Asked Questions

◄ UKU controller installation

All UKU controllers come with several extra features   Lights/ventilation and vaporiser control Door sensor Overheating protection Child lock Timer UKU Wi-Fi and UKU GSM controllers also have a remote control option through the mobile app

The set includes   Control panel; Main module; Temperature sensor; Door sensor; Temperature/door switch cable (5+5 m; 2 x 0.22 mm²); User interface cable (3 m; 4 x 0.34 mm²).

Important things to know before installation   Only a qualified electrician may install the device. Make sure that the building’s cables from the main switchboard to the desired location in the sauna have a sufficient cross-section. In case of an older building, pay attention to the condition of the connecting boxes and if possible, install a new cable from the switchboard to the sauna. We recommend connecting the unit to the mains without an earth-leakage circuit breaker. The cable connecting the main module with the heater must be heat-resistant (90°C). All the cables will connect to the main module.

Where should the control device be installed?   The control panel must be installed outside the steam room at the user’s eye level next to the door or according to the manufacturer’s recommendations. Install the main module in a dry place that is easy to access. We do not recommend installing the main module in the sauna room. Doing so will be at your own risk. The main module should be installed in a place where the ambient temperature does not exceed 50°C and relative humidity is not higher than 95%. The protection degree of the device is IP65. If your control device supports the use of Wi-Fi or GSM connections, make sure you install the main module where the appropriate reception is available.

◄ Problems with controllers

The temperatures differ on the remote control and sauna thermometer   Some difference in the measured temperature is considered normal because of the measurement uncertainties of the devices. If the difference is more than 10-15 degrees you should check your temperature sensor and sauna thermometer. Are the temperature sensor and sauna thermometer placed in different parts of the sauna room where temperatures are actually very different? Is the temperature sensor too close to the heater? Too close to the door? The best place to install it is on the opposite wall from the heater approximately 15 cm from the ceiling and away from ventilation tubes and windows. Does your sauna thermometer work properly? You probably need to replace your temperature sensor when even after fixing all the above-mentioned issues: The temperature difference is more than 20 degrees the temperature displayed on the remote control changes very suddenly or keeps fluctuating the message “Sensor error” is displayed There could be a problem with the cable connection. Take down the sensor and try connecting it to the main module using another suitable cable. If the sensor works, you just need to replace the cable. If it still does not work, the sensor needs to be replaced. In these cases, please contact us at support@usbathstore.com

The remote control display does not turn on   In most cases, this happens when the cables of the remote control are not connected correctly. First, you should make sure that all the cables are connected to the main module according to the scheme in the installation manual. This should preferably be done by a certified electrician. Also, check if any cables attached to the remote control have come loose. If after checking all the cables the remote control still doesn’t work, please contact us at support@usbathstore.com

The controller does not establish a network connection   If your UKU GSM controller does not connect to the network after connecting your app user account to the controller, please contact us and send a photo of the log (Menu -> GSM status -> log). If your UKU Wi-Fi controller does not connect to the network: Make sure you are using a 2.4GHz Wi-Fi network, instead of 5GHz. Make sure your different Wi-Fi networks don’t have the same name and that the chosen network name is no longer than 20 characters. If your Wi-Fi controller still does not connect to the network, take a picture of the error log displayed after pressing “Connect”, and e-mail it to us at support@huum.eu.

The controller lost its network connection   Are you using the SIM card that arrived with the controller? Contact us at support@usbathstore.com Are you using another SIM card? Check if the mobile data has run out. Find out if your service provider has changed the APN settings. If the APN settings have changed, update the settings also in the settings menu of the controller. Take the SIM card out and try if it works on your phone. If none of this helped, contact us at support@huum.eu.
