2. INSTRUCTIONS FOR USE

Before you switch the heater on check always that there aren't any things over the heater or in the near distance of the heater.

2.1. General

The wireless control unit is equipped with a user-prompting touch screen and is operated by three AA rechargeable batteries. The unit comes with a recharge stand. The recharge stand can be mounted into the wall or to the table but it must be placed outside the sauna room. Never take the wireless control unit to a heated sauna!

The wireless control unit is activated by pressing the black power switch above the screen. Activation brings the Start Menu with the function icons to the screen. Pressing a function icon switches the corresponding function on or off. Activated functions are indicated by a dark spot in the corner of relevant function icons and by 'active function' images above the screen.

The touch screen can be operated using a finger or, for example, the blunt end of a pencil. Avoid pressing the screen unnecessarily hard!

Clean the touch screen from time to time with a cloth or mild alcohol wipe.

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 uninterrupted 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 Function Icons

You can control all functions of your sauna using the function menus or the function icons.

Function Icons

Light, Fan and Colour Light are activated by pressing the relevant function icon on the screen.

Sauna ON/OFF

Press the Sauna ON/OFF icon to enable communication between the power unit and the wireless control unit. The wireless control

unit now displays information on the conditions in your sauna, such as temperature and humidity. Should the connection between the power unit and the wireless control unit be lost during the bath, the power unit will nevertheless be able to perform the programmed functions since all the settings remain stored in its memory.

Settings (operating time, temperature, humidity etc.) made in the Sauna ON mode only affect the current bath.

Settings made in the Sauna OFF mode are default settings which are stored in the memory of the wireless control unit.

The Set the Pre-Setting Time icon takes you directly to the screen where you can set the pre-setting time.

Pressing the Main Menu icon brings the function menus to the screen.

Through the Main Menu you can change all the settings related to your sauna. The function menus are explained in detail further below.

The pictures shown in this manual are meant as guidelines only since the screens may vary according to which features have been acquired and enabled for use.

Function icons can be added and removed from the screen. See 2.9.9. 'b) Installed / Enabled Features'.

2.3. Sauna Time Setup

Through the Sauna Time Setup menu you can make timer settings for your sauna.

• The operating time is the time the heater is on.
- The pre-setting time is the delay period after which the heater starts heating up the sauna. Do not forget to activate Heater ON and/or Steamer ON icon on the screen, depending for which function you wish to set the pre-setting time.

From the

Main Menu choose

2.4. Heater and Steamer Setup

2.4.1. Heater Setup

Under the Heater Setup menu you can set the temperature that the heater is expected to create in the sauna room.

While the AUTO ON icon is activated, the heater will switch on automatically when you press the Sauna ON/OFF icon. To switch on the heater with the AUTO ON icon deactivated, press the Sauna ON icon and then activate the Heater ON/OFF icon.

To keep your sauna in a good condition for longer, it is important that you have it dehumidified after bathing. With Fenix you can do this by leaving the heater on for a desired period at a temperature of 40 °C. Once the function is activated, it will stay on 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. Confirm the settings.

While the AUTO ON icon is activated, the steamer will switch on automatically when you press the Sauna ON/OFF icon.

2.7. Week Timer

Electrical safety regulations allow the week timer feature to be used only in community saunas!

The week timer settings allow you to program a weekly schedule, which is especially handy if you use your sauna regularly every week. Set the desired bathing time for any chosen day – or even every day – of the week.

When the weekly schedule starts, the wireless control unit will be activated even if switched off.

A pause of at least 6 h is required between each two periods created for the Week Timer schedule.

Week Timer Menu:

Choose Enable Program to activate all created programs to be run at set times.

View Schedule brings to the screen a recap of your weekly schedule if you have created one; if you do not have one, the display shows 'Week timer program is empty'. You can also change the schedule in this menu.

Create New Program Timing

• Set the program start time, which is the time you wish to start bathing. Confirm or, if you wish to return to the previous screen, cancel.
• Set the program ending time and confirm or cancel.
• Set the day(s). You can set more than one day at the same time.
• Confirm the settings or press Cancel to return to the previous screen.
• Set the desired temperature for the programmed period.
• Set the desired humidity level for the programmed period. Make sure you have the Enable Steamer box ticked.

- Confirm the settings or press Cancel to return to the previous screen.

The display now shows a recap of the settings made. Confirm or press Cancel to return to the previous screen.

If you choose View Schedule again after programming, the displayed week timer schedule will contain the period you just programmed. Here you can change the schedule or, for example, remove a schedule without deleting it permanently, meaning that it will remain stored in the memory for later activation. You can also add/create new schedules. See the following pages for examples.

Delete All Periods deletes all the periods created for a week timer schedule. If you choose this option, the display will show a message asking you to confirm that you wish to delete all periods. Confirm or cancel as required.

Check Validation checks the status of the Week Timer schedule and displays any possible problems on the screen.

• Heating periods: checks the heating period length to make sure the max. operating time is not exceeded.
• Resting periods: checks that the pauses in the Week Timer schedule are at least 6 h.
• Periods enabled: displays the activated periods of the weekly schedule.
  • Master enable: on / off.
• Check progress: indicates the stage of the check.
