• 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

• 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)

• 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.

• 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.

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

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

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.

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.

With UKU LOCAL you can heat the sauna from the control panel. With UKU WI-FI and UKU GSM, you can heat the sauna from the control panel and also from HUUM mobile app.
