2.1.1. Batteries
The instructions for fitting/changing the batteries can
be found on page 59. The Fenix wireless control unit
comes with NiMh AA HR6 rechargeable batteries,
voltage 1,2 V. The rechargeable batteries can be
replaced with non-rechargeable AA batteries. Note!
Never place the wireless control unit in the recharge
stand when fitted with non-rechargeable batteries. Do
not use rechargeable and non-rechargeable batteries
simultaneously together.
New, unused batteries must be charged uninterruptedly
for 24 hours before use. A complete recharge takes
12 hours. It is recommended to keep the wireless
control unit in the supplied recharge stand when the
unit is not in use – this way the batteries have charge
when the unit is needed again.
Never use a damaged charger or battery. Remove
the damaged battery from the unit. Dispose of the
batteries according to the local regulations (concerning
recycling etc.). Do not place batteries in household
waste. Remove the batteries before disposing of
the unit. Remove the unit from the charger before
fitting/changing batteries.
2.2. Function Menus in the Main Menu and

until the setting is changed by the user.
2.4.2. Steamer Setup
The steamer is controlled through the Steamer Setup
menu. One of the two modes must be selected:
1) In the %RH Mode (%RH = relative humidity
expressed as a percentage) the humidity sensor
measures the humidity in the sauna room and the
wireless control unit controls the steamer so that
the humidity level is maintained as close to the set
value as possible during the bath.
Set the desired humidity %RH. The sum of the
steamer %RH setpoint and the max. heater setup
cannot exceed 140.
2) The Interval Mode means that the steamer is
on and off periodically. Set the desired duration of
the two periods: for example the ON period at 140
seconds and the subsequent OFF period at 85 s.

the power unit through the cable and batteries can
not be used. If connected to the power unit with
a cable, the wireless control unit can be fixed to
a wall using a special rear cover designed for wall
mounting (see Figure 3). In this case you do not
need a recharge stand.
When you first switch on the wireless control
unit, it will automatically prompt you to calibrate the
touch screen. The screen will guide you through the
calibration process. After this you are asked to choose
the desired panel language and set the day and time.
Make the required settings and confirm. If the unit
does not follow the above steps automatically, they
can be carried out manually (see Quick Guide).
