OPERATION OF THE CONTROL UNIT
Switch the control unit on using the main switch (9), located on the front panel of the unit.
When you wish to begin heating the sauna, press the On/Off-button(1), leaving the unit in its basic mode. In this mode, the
LED light located next to the on-off switch will remain lit. The control unit will begin heating the sauna, indicating the
measured temperature on its display.
Now that the unit has been switched on, the desired temperature value can be set or the required pre-selection or operating
time selected. These adjustments are made in the following manner:
SETTING THE PRE-SELECTION TIME
Press the highest (3) of the three adjustment buttons to make the control unit enter the pre-selection time adjustment mode.
After this has been done, press the up (6) and down (7) arrows to choose the desired pre-selection time, and then press the
PROG/OK-button (8) once you have selected the time. If you press the pre-selection button again, the unit will return to its
basic mode without having changed the pre-selection setting.
When the pre-selection time has been set, the control unit display (10) will indicate the remaining pre-selection time and the
LED light located next to the pre-selection button will remain lit. The control unit will wait until the chosen pre-selection time
has expired and then switch the sauna heating mode on. The control unit will be on for six hours unless it is switched off.
The pre-selection time can be adjusted to be between 0 and 24 hours.
SETTING THE OPERATING TIME
Press the middle button (4) on the row of three adjustment buttons to make the control unit enter the operating time
adjustment mode. After this has been done, press the up (6) and down (7) arrows to choose the desired operating time, and
then press the PROG/OK-button(8). If you press the adjustment button (4) again, the unit will return to its basic mode without
having changed the setting.
Once the operating time has been set, the control unit will heat the sauna for the established time, and once this time has
expired, the control unit will automatically switch itself off. The LED light located next to the operating button will remain lit
whenever an operating time has been set.
The operating time can be adjusted anywhere between 0 and 6 hours in 10 minute increments. In professional use the
interval is 0 –12 hours, see paragraph “Changing the max operating time limit” below.
SETTING THE TEMPERATURE
Press the lowest (5) of the three adjustment buttons to make the control unit enter the temperature adjustment mode. After
this has been done, press the up (6) and down (7) arrows to choose the desired temperature, and then press the PROG/OK-
button(8). To return from this mode to the basic mode, press the temperature adjustment button again.
The temperature can be adjusted to be between 40°C and 100°C. The last set temperature will remain in the control panel’s
memory even when the unit is switched off with the main switch.
SAUNA LIGHT
The control unit can be used to switch the lighting on and off by pressing the Sauna light-button (2). This function is fully
independent of the other functions.
CHANGING THE MAX OPERATING TIME LIMIT
The longest operating time for a sauna heater in private use is 6 hours. In public use the maximum time is 12 hours. The
control panel factory setting for operating time is always 6 hours, but it can be changed where applicable by doing the
following procedure:
1. Press the On/Off-button(1) to set the control panel in on-mode
2. Press the Operating time-button(4). The led next to the button will start flashing as an indication of 6 hour limit
3. Press and hold simultaneously the Temperature-button(5) and the Adjustment down-button(7) until both the
Operating time-led and the Temperature-led are flashing
4. When both leds are flashing press the Prog/OK-button to finalize the change
5. The control panel can be changed back to 6 hours by repeating the procedure (the leds flashing will be the
opposite)
