## General

With the digitalSTROM Ventilation Controller App you configure the settings for your ventilation and air recirculation units in the individual rooms or in the entire home. While doing so, you adjust the number of ventilation levels to the ventilation units, define the automatic behavior of the apartment ventilation or set up applications such as toilet ventilation.

The number of available ventilation levels is required in order to limit the choice during operation when using a Smartphone or room control unit.

## Preconditions

- You need at least one dSM12 in the relevant power circuit in order to operate ventilation and air circulation units.

## 'Overview' Tab

You can see the current status of your ventilation and air recirculation units at a glance in the Overview.

Under Apartment, the current level of the apartment ventilation will be displayed if you have installed such a system and have connected it to digitalSTROM.

Under Rooms, the rooms in which ventilation and/or air recirculation units are installed will be displayed together with the selected intensity level.

References to faults and service requests are displayed under Messages and events.

## 'Room-based Ventilation and Air Recirculation' Tab

The available levels for the ventilation and air recirculation units installed in the room are defined in this tab. You have the following setup options:

- Ventilation can be turned off: Defines whether the ventilation system can be turned off completely by using the connected actuator terminal block or runs continuously at the minimum level.
- Available ventilation levels: Here you set the predefined number of ventilation levels of your installed units. A maximum of 4 ventilation levels can be selected.

Boost mode settings: The ventilation can be set to a boost mode via the controls. This activates the highest ventilation level and resets the normal ventilation level automatically after a predefined time period has elapsed.

- Always enable boost mode timer for highest level: If you select this option, the highest ventilation level cannot be set continuously. This means that the highest level is only available for a limited period and can help you to save energy, for example.
- Set normal level after boost mode was active for: Here, you determine the duration of the boost mode
- Normal level after boost mode: Here you define the ventilation level that is selected after the boost mode has been stopped.

## 'Apartment ventilation' Tab

If an actuator terminal block was set to the 'Apartment ventilation' color group, this tab will be displayed automatically. This allows the ventilation levels of a connected ventilation unit to be controlled directly from the digitalSTROM environment. The behavior during absence, the boost mode as well as an increase of the ventilation level if the humidity in the apartment exceeds a defined level are handled automatically by this App. The user can also select the required ventilation level manually via connected room control units or via the Climate Control Smartphone App. Furthermore, the ventilation levels can also be selected in the server-apps in order to define a timer, for example.

Additionally, a fault with respect to any necessary maintenance is also displayed if the relevant sensors are connected and configured for this purpose. The malfunction and service signal can also be used in the server Apps as a trigger in order to send a push message, for example.

In the apartment ventilation tab, the required settings for the ventilation system and the expected behavior of the ventilation can be defined:

### Ventilation system:

The settings define which ventilation levels of the connected actuator terminal block are supported with respect to the ventilation system and limit the control options of the user to these levels.

- Ventilation can be turned off: Defines whether the ventilation system can be turned off completely by using the connected actuator terminal block or runs continuously at the minimum level.
- Available ventilation levels: Here you set the ventilation levels predefined by the system. A maximum of 4 ventilation levels can be selected.
- Output devices: Displays the devices installed and configured for the apartment ventilation.
- Malfunction sensor: If the ventilation system provides a malfunction signal, this can be read in via a SW-UMR or SW-AKM. For this purpose, the sensor functions in the device properties dialog must be defined as malfunction in the apartment ventilation group.
- Service sensor: If the ventilation system provides a service signal, this can be read in via a SW-UMR or SW-AKM. For this purpose, the sensor functions must be defined in the device properties dialog as service in the apartment ventilation group.

### Behavior of the ventilation:

These settings define the behavior of the ventilation levels during operation. The following options can be selected here.

- Normal level when being at home: Here, you set the ventilation level during presence.
- Set normal level after boost mode was active for: The ventilation can be set to a boost mode via the controls. This activates the highest ventilation level and resets the normal ventilation level automatically according to the time predefined here.
- Always enable boost mode timer for the highest level: If this option is set, the highest ventilation level cannot be set continuously in order to save energy. Only the boost mode is available, which activates the highest level for a limited period only.
- Reduce ventilation level when absent: This setting defines which ventilation level should be set during absence.
- Set highest ventilation level if humidity exceeds: If the defined humidity is exceeded, the highest ventilation level is set in order to ventilate more intensively. To calculate the humidity, all humidity sensors available in the home are taken into account.

## 'Ventilation Wizard' Tab

In this tab, automatic ventilation can be set for the rooms equipped with a ventilation unit. Here, the ventilation can switch on automatically if

- the light in the room is switched on
- a motion detector in the room triggers
- a defined humidity threshold value in the room is exceeded

This means that the ventilation is activated for a predefined duration. The automatic system can also be limited to a specific time of day so that the ventilation does not start automatically, such as during the night.

You can set and then save the following settings for each room:

- Activated ventilation level: Here, you select the ventilation level at which the ventilation should run.
- Duration: Here you select how long the ventilation should continue to run after the trigger has become inactive again. After this time has elapsed, the previously set level becomes active again.
- Trigger: Here you select which triggers should start the ventilation. Please note that you can only select triggers that are also available in your digitalSTROM installation:

- Light in the room (requires digitalSTROM light control in the room)
- Motion detected in the room (requires a digitalSTROM motion sensor in the room)
- Humidity gets too high: humidity threshold value with the following setting options (requires a digitalSTROM humidity sensor in the room):

- Threshold value in % of relative humidity

- Active time window: here, you define the period in which the wizard should be active during a day. In this way, for example, you can prevent a fan from switching on and making unwanted noises at night.

The automatic system can be switched off for a room by unchecking the box in the 'Active' column.
