Appliance description

This device is intended to adjust the fan stage automatically or manually. The device incorporates a filter change indicator that is subject to the hours run.

1. Operating mode key
2. Air quality LED indicator
3. Rotary selector for selecting the required air quality
4. LEDstrip for indicating the selected operating mode

Note
All LEDs flash simultaneously to indicate that the filter in the ventilation unit needs to be changed.

appliance type and settings, the fans are either idle or generate the minimum airflow.
Automatic mode| The ventilation unit changes from setback mode to standard mode when the air quality is poor. The air quality indicator illuminates.

Note
After the power supply has been switched on, the device will be in automatic mode.

Select from the various operating modes by repeatedly touching the operating mode key.
The LED strip indicates the selected operating mode.

Adjusting the air quality
You determine the air quality you perceive as optimal by switching the air quality rotary selector higher step by step.
The device incorporates an air quality sensor, that reacts to gases and vapors that can oxidize, such as carbon monoxide, methane, isobutane, hydrogen, and ethanol. Such gases may be generated by smoking, cooking, or when a larger number of people congregate in one room, for example.
The air quality indicator illuminates when the constituents in the air exceed the selected value.

Maintenance

Filter change
The device is equipped with an integral timer function to indicate when the filter in the ventilation unit should be changed.
All LEDs will flash simultaneously if a filter change is required.
Note
The filter change intervals determined by the device are guidelines only and may deviate from the actual level of filter contamination.
Observe the filter change indicator of the connected ventilation unit.
Subject to the selected operating mode, the filter may need changing every 2 to 6 months. In the case of permanent party mode, the device will signal a need for a filter change after only 2 months. If the unit operates primarily in setback mode, the interval will stretch to a maximum of 6 months.
In standby mode, the device stores the remaining time up to the next filter change and will restart with that value when the unit starts up again.

Note
Following a filter change, hold down the operating mode key for at least 3 seconds, in order to reset the filter change timer function.

Safety

Only a qualified contractor should carry out the installation, commissioning, maintenance, and repair of the appliance.
General safety instructions

Instructions, standards, and regulations
Note

• Observe all currently applicable regulations and requirements.

Preparations

Installation site
The device is suitable for mounting on a surface box or on level surfaces.
Note
Select an installation location inside the lead room that is suitable for capturing the air constituents.
Preparing the device for installation

Rotary selector
Carefully lever out the rotary selector using a small screwdriver.

Locking screw

• Undo and remove the locking screw.
• Initially pull away the front cover from the r.h. side and then entirely.

Assembly
WARNING Electrocution
The device is supplied with power via the connecting cable that links it to the ventilation unit. There is a risk that you could touch ‘live’ parts during the installation.

• Therefore isolate the ventilation unit from its power supply.
  

Fixing holes
Using the fixing holes, you can secure the base either on a surface box or in a suitable location on a wall.
Mounting on surface box
Note

• Mounting on a surface box requires that both surface box screws are on the vertical plane.
• Undo both surface box screws.
• Position the base on the surface box. Whilst doing this, insert the surface box screws through the base fixing holes.
• Align the base and tighten the screws.

Wall mounted installation
Material damage
When drilling fixing holes, check for the possible presence of cables that may run underneath the plaster.

Note

• To secure the base, use rawl plugs and screws that are appropriate for the type of wall construction.

Power supply
Note

• Keep the cable core ends of the power cable as short as possible to prevent them protruding beyond the terminal area, and avoid contact with the PCB elements.

Wiring diagram

Note

• When assigning terminals, observe the operating and installation instructions of the connected ventilation unit.
• Apply the stripped wires in accordance with the wiring diagram.
• Route the cores of the power cable in front of the terminal Strip to save space.
• Guide the front cover on the I.h. side at a slant into the groove of the base.
• Push the front cover onto the base.
• Insert the locking screw and tighten it.
• Push on the rotary selector.

Commissioning

Commissioning

• Switch on the power supply to the ventilation unit.

Note
After the power supply has been switched on, the device will be in automatic mode.

• Check for correct function.

Appliance handover

• Explain the device’s functions to the users and familiarise them with its operation.
• Instruct the user on the filter change indicator.
• Make users aware of potential dangers and what to do in the case of a fire.
• Hand over these instructions.

Shutting down

Note
The device is supplied with power via the connecting cable that links it to the ventilation unit.

• Isolate the ventilation unit from the power supply.
