Frequently Asked Questions - Mia Karibu

How to turn on the sauna control?

Press the ON/OFF switch (8). The display shows flashing 00.00, the control is operational.

How to start sauna mode with quick start?

Set the desired temperature with the temperature selector (4), then briefly press the timer button (9). The stove heats up and the control light (3) turns on.

How to program a delayed start?

Set the temperature (and humidity in hybrid mode), then press and hold the timer button (9) until the desired duration is reached (in 15-minute steps, max. 23h45). Release: the timer is displayed and heating starts after the delay.

What does the flashing 'FILL' display mean?

The water tank of the evaporator is empty. Fill it; after a few moments, the message disappears and the evaporator resumes.

How to clean the sauna control?

Use a soft cloth dampened with mild soap, well wrung out. Wipe the housing gently. Never immerse or pour water on the device.

What to do in case of error message E-F1 or E-F2?

These errors indicate a sensor defect (stove or bench). Note the message, cut off power, and contact a qualified electrician to check the cables and sensors.

Does the display flash '00.00' after 6 hours of operation?

This is normal: the heating duration limit automatically stops the stove. Briefly press the timer button (9) to restart.

Can I use the control with children?

The control must not be used by children under 8 years. Children over 8 years or persons with reduced capacities may use it under supervision.

How to install the stove sensor?

Mount the sensor in the upper half of the stove, about 15 cm from the ceiling. Maintain sufficient distance from air inlets. The cables must be separated from other cables.

What to do if the lighting does not turn on?

Turn off the control, cut the main fuse, replace the bulb (max. 100 W, fuse 1 A T). If the problem persists, contact your supplier.

EN

2.2. Safety information for the installer

• Installation may only be performed by a qualified electrician or similarly qualified person.
• Installation and connection of the sauna control unit may only be performed when the power supply is disconnected.
• An all-pole disconnecting device with full cut-off must be fitted on-site in accordance with overvoltage category III.
• The sauna control unit must be installed outside the sauna cabin at a height of approx. 1.70 m, or in accordance with the recommendation given by the sauna manufacturer. The ambient temperature must be within a range spanning -10 °C to +40 °C.
• The heater sensor must be attached in a way that ensures it is not affected by an inflow of air.
• Observe all regulations applicable at the installation location.
• For your own safety, consult your supplier in the event of problems that are not explained in sufficient detail in the installation instructions.

2.3. Safety information for the user

- The sauna control unit must not be used by children under 8 years of age.

- The sauna control unit may be used by children above 8 years of age, by persons with limited psychological, sensory or mental capabilities, or by persons with lack of experience/knowledge:

3.1. Scope of delivery

- Single-component sauna control unit

- Heater sensor with integrated excess temperature fuse (F1), sensor wires 3 m

- Bench sensor (F2), sensor wires 3 m

• Installation accessories

3.2. Product functions

The Modern Bio sauna control unit is used to control and regulate combi sauna heaters with a heating output of up to 9 kW and an evaporator output of up to 3 kW in the temperature range spanning 40 °C to 125 °C and a humidity range spanning 0 to 100%.

A power booster allows the maximum contact rating to be increased from 9 kW to 18 kW or 30 kW.

The sauna control unit functions according to a two-sensor system. The excess temperature fuse is located in the heater sensor housing. Should the sauna heater continue heating after reaching the preferred temperature due to a defect, the excess temperature fuse switches the sauna heater off at a temperature of approx. 139 °C.

Dry heat is provided in sauna mode. The temperature in the cabin is high (80 to 100 °C). The humidity level is low and does not exceed 10%. If the sauna cabin temperature is lower than the set temperature, the sauna control unit switches on the sauna heater. The sauna heater heats up. If the sauna cabin temperature exceeds the set temperature, the sauna control unit switches off the sauna heater.

The sauna heater will not heat up again until the sauna cabin temperature falls below the set temperature.

The evaporator operates along with the sauna heater in combi mode. The temperature in the cabin is lower (approx. 40 to 65 °C) than in sauna mode, with the relative humidity being considerably higher, ranging from 35% to approximately 70%. The maximum humidity level which can be set depends on the temperature of the sauna. The higher the sauna temperature, the lower the maximum humidity level which can be set.

For safety reasons, the heating period limiter automatically switches off the sauna control unit after heating for a period of 6 hours.

The Modern Bio sauna control unit has a preset time function. The preset time can be set to increments of 15 minutes. The minimum preset time is 15 minutes. The maximum preset time totals 23 hours and 45 minutes. Once the preset time has elapsed, the sauna heater switches on.

4. Installation and connection

ATTENTION!

Damage to the unit

The sauna control unit is protected against jets of water, however direct contact with water could still damage the unit.

- Install the sauna control unit in a dry place at which a maximum humidity of 95% is not exceeded.

ATTENTION!

Damage to the unit

- The sauna control unit may only be used for operating and regulating 3 heating circuits with a maximum heating capacity of 3 kW per heating circuit and a maximum evaporator capacity of 3 kW.

Observe the following points when installing and connecting the sauna control unit:

- The sauna control unit must be installed outside the sauna cabin at a height of approx. 1.70 m, or in accordance with the recommendation given by the sauna manufacturer. The ambient temperature must be within a range spanning -10 °C to +40 °C.

- There must be a fixed connection for the electrical power supply.

- An all-pole disconnecting device with full cut-off must be fitted on-site in accordance with overvoltage category III.

- The heater sensor wires must be laid separately from the other mains wires and control wires. Wires with only one layer of insulation must be protected by using a pipe (double insulation). The heater sensor and the bench sensor may only be connected using the sensor wires provided, which are heat-resistant up to 150 °C.

• The heater sensor must be installed in the sauna cabin above the middle of the sauna heater. A distance of approx. 15 cm to the sauna cabin ceiling must be maintained.
• The heater sensor must be attached in a way that ensures it is not affected by an inflow of air.
• The bench sensor must be installed opposite the heating system. A distance of approx. 15 cm to the sauna cabin ceiling must be maintained.

During the preset time

If a person enters the sauna cabin while the timer is running, they might place flammable objects on the cold sauna heater. Once the preset time begins, the sauna heater begins to heat the cabin. Flammable objects on the sauna heater ignite and cause a fire. The door monitor is meant to prevent this.

The preset time was set (see section 9.5 and 9.6).

▶ The timer is running and the sauna heater is not yet heating up.

The cabin door is opened.

▶ A recurring beep can be heard.

▶ The preset time is cancelled.

▶ After the cabin door is closed, the preset time must be set again.

While the sauna heater is heating

The cabin temperature is below 40^ C and the cabin door is opened.

▶ A recurring beep can be heard.
▶ The message “door” appears in the display 2.
▶ After the cabin door is closed, the sauna control unit must be started again.

The cabin temperature is above 40 °C . The door monitor is no longer used for fire prevention, but as a power-saving feature.

When the cabin door is opened for less than 5 seconds, there is no message.

The cabin door is opened for more than 5 seconds:

▶ A recurring beep can be heard.
▶ The control light ③ flashes.
▶ The sauna heater is switched off.

▶ The message “door” appears in the display 2 .
▶ After the cabin door is closed, the sauna heater is switched on again, the beeping stops, and the message “door” disappears.
