Installation of UKU sauna control system

Contents of the set

UKU sauna control system set contains all components that are necessary for mounting and using the control system:

• Sauna control panel (CLASSIC Black)
• Cable for the sauna control panel (118 in/3 m; 4×22 AWG)
• Main module
• Temperature sensor
• Door sensor
• Cables for temperature and door sensors (197+197 in/5+5 m; 2×24 AWG)

Functions of the control system

• Child lock
  The child lock function ensures safety when using the sauna control panel in families with small children.

• Steamer
  The steamer function enables one to configure the intensity of the steamer that is connected to the control system.

• Lighting
  The lighting function enables one to switch the sauna room light fitting that is connected to the control system on or off.

• Steamer safety
  This is a safety function that informs you when the steamer has run low on water.

• Heating time
  You can use the settings of the control panel for configuring the maximum heating time – the control system switches the sauna heater off automatically when the preset time has passed.
• Temperature unit
  You can select the desired unit for the sauna temperature.
• Heating algorithm
  You can select between Simple and Smart heating algorithms. Simple algorithm keeps all heating elements switched on until the desired target temperature is achieved. Smart algorithm starts gradually turning the heating elements off before the target temperature is reached. Smart algorithm helps to reduce the consumption of electricity, especially in heaters where the quantity of sauna stones is big (> 110 lb).
• Vent/light
  This function enables one to automatically switch the ventilation system or sauna lighting fitting that is connected to the control system on for 10, 15, or 20 minutes whenever the door is opened.
• Timer
  You can configure the start time for sauna heating with increments of 30 minutes.
• Door sensor
  The door sensor enables one to prevent overheating and switches the sauna heater off when the steam room door is open.
• Temperature sensor with overheating protection
  Overheating protection is employed when the temperature of the sauna room has risen to approximately 266°F (130°C) degrees in order to prevent thermal damage.

Important considerations before installation

Before installing the unit, read the user manual carefully. This enables one to utilize all the necessary functions and prevent accidents that may arise from ignorance.

• Only an electrician or a specialist with equivalent qualification may install the unit.

• Installation and maintenance works may only be performed when the unit is not powered on.
• If you encounter problems that are not covered in the user manual of the UKU sauna control system, contact the distributor of the unit for advice.
• It is forbidden to modify or remodel the unit without authorization.
• Ensure that the cross-section of the cabling between the building’s switchboard and the main module and the sauna heater is sufficient. Proper cross-section depends on the power rating of the sauna heater and is provided in the user manual of the sauna heater.
• In the case of an older building, check the condition of the junction boxes and, if possible, install a new cable between the switchboard and the sauna. Install a separate current protection device for the sauna.
• It is recommended to connect the device to the mains without a Residual-current device (RCD).
• UKU sauna control system is meant to be used with equipment that complies with the requirements stipulated in EN 60335-2-53:2011.

Installation of UKU sauna control system

• Before installing the unit, disconnect the supply current of the respective cables from the switchboard.
• The sauna 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.
• If your main module supports a Wi-Fi connection, choose a location with signal propagation. Insulated spaces and cabinets (such as the sauna room or metal switchboards) are not suitable.
• The main module must be installed in a dry place. The protection degree of the device is IPX4. The power cables must be anchored
  via the provided cable gland.
• In order to prevent damage, ensure that the temperature of the operating environment of the main module remains between -4 °F and 104 °F. The relative humidity of the room should not exceed 95%.
• Before powering the controller, make sure that the main module is sealed so that there is no possibility for pollution or only for dry, non-conductive pollution to occur on the components inside the main module while in use. All the cable inlets and the module box shall be properly sealed.
