INSTRUCTIONS FOR USE

Using the Heater

When the control unit is connected to the power supply and the main switch (see figure 1) is switched on, the control unit is in standby mode and ready for use. I/O button’s background light glows on the control panel.
WARNING! Before switching the heater on always check that there isn’t anything on top of the heater or inside the given safety distance.

Heater On

Start the heater by pressing the heater I/O button on the control panel.

When the heater starts, the top row of the display will show the set temperature and the bottom row will show the set on time for five seconds.
When the desired temperature has been reached in the sauna room, the heating elements are automatically turned off. To maintain the desired temperature, the control unit will automatically turn the heating elements on and off in periods.
If the heater efficiency is suitable and the sauna has been built correctly, the sauna takes no more than an hour to warm up.

Heater Off
The heater turns off and the control unit switches to standby-mode when

• the I/O button is pressed
• the on-time runs out or
• an error occurs.

NOTE! It is essential to check that the control unit has cut off power from the heater after the on-time has elapsed, the dehumidification has ended or the heater has been switched off manually.

Changing the Settings

The settings menu structure and changing the settings is shown in below.
The programmed temperature value and all values of additional settings are stored in memory and will also apply when the device is switched on next time.

Using Accessories

Lighting and ventilation can be started and shut down separately from other functions.

Lighting

The lighting of the sauna room can be set up so that it can be controlled from the control panel. (Max 100 W.)

INSTRUCTIONS FOR INSTALLATION

The electrical connections of the control unit may only be made by an authorised, professional electrician and in accordance with the current regulations. When the installation of the control unit is complete, the person in charge of the installation must pass on to the user the instructions for installation and use that come with the control unit and must give the user the necessary training for using the heater and the control unit.

Installing the Control Panel

The control panel is splash proof and has a small operating voltage. The panel can be installed in the washing or dressing room, or in the living quarters.
If the panel is installed in the sauna room, it must be at the minimum safety distance from the heater and at a maximum height of one metre from the floor. Figure 2.
Conductor tubing (ø 30 mm) inside the wall structure allows you to thread the data cable hidden within the wall – otherwise the installation will have to be on the wall surface. We recommend you to install the control panel embedded in to the wall and far away from possible splashes.

Installing the Power Unit

Install the power unit to a wall outside the sauna room, in a dry place with an ambient temperature of >0 ºC. See figure 3 for instructions on how to open the power unit cover and how to fix the unit to the wall.
Note! Do not embed the power unit into the wall, since this may cause excessive heating of the internal components of the unit and lead to damage. See figure 3.

Electrical Connections
Figure 4 shows the electrical connections of the power unit. For more detailed installation instructions see the instructions for installation and use of the selected heater model.

Power Unit Fuse Faults
Replace a blown fuse by a new one with the same value. The placement of the fuses in the power unit is shown in figure 4.

• If the fuse for the electronic card has blown, there is likely a fault in the power unit. Service is required.
• If the fuse in the line U1 has blown, there is a problem with lighting. Check the wiring and functioning of lighting.

Power extension unit LTY17 (optional)
The maximum load of control unit can be increased by 17 kW by using power extension unit LTY17.
The power extension unit includes detailed instructions of installation.

Installing the Temperature Sensor

Note! Do not install the temperature sensor closer than 1000 mm to an omnidirectional air vent or closer than 500 mm to an air vent directed away from the sensor. See figure 7. The air flow near an air vent cools down the sensor, which gives inaccurate temperature readings to the control unit. As a result, the heater might overheat.

Installing the Temperature Sensor WX232
Check the correct location for the temperature sensor from the heater’s instructions for installation and use.

Wall-mounted heaters (see figure 5)

• Fasten the temperature sensor on the wall above the heater, along the vertical centre line running parallel to the sides of the heater, at a distance of 100 mm from the ceiling.

Floor-mounted heaters (see figure 6)

• Option 1 : Fasten the temperature sensor on the wall above the heater, along the vertical centre line running parallel to the sides of the heater, at a distance of 100 mm from the ceiling.
• Option 2 : Fasten the temperature sensor to the ceiling above the heater, at a distance of 100–200 mm from the vertical centre line of the heater’s side.
