Product description and instructions for use

The SEVi 160 ventilation system with heat recovery available in different variants is used for controlled living space ventilation.

A SEVi 160 ventilation system includes at least 2 SEVi 160 fans and a control unit SEC-20. Ideally, an even number of devices is to be installed (exception: SEVi 160 DUO).

Principle of heat recovery

5

The devices belonging to the ventilation systemare operated in opposite directions in the heat recovery mode. This means that in pairwise operation each fan alternatively expels used room air to the outside and replaces it by fresh air which has been pre-heated in the heat accumulator. The direction of the fan is changed in intervals of 75 seconds. The ventilation system is operated with 12 V and exclusively consists of high-quality materials.

In addition to the heat recovery mode, intensive brief ventilation is possible (permanent intensive brief ventilation at fan stage 4) in which, depending on the installation condition of the fans, a constant air stream is provided towards one direction to ventilate the room without opening the window (noise protection).

The operation of the ventilation system is recommended throughout the year. In the seasonsin which heating appliances are not necessary, the ventilation system acts in a contrary manner. Here, summer operation (intensive brief ventilation, passive cooling) is recommended, and in this mode, the generally lower inside air temperature of the morning hours is maintained in the living space analogue to the principle of heat recovery.

When the ventilation system is not in use (important during the heating season), the upper part of the interior panel is to be turned by 180° to close the interior panel to avoid, for example, that heat escapes out of the building in an uncontrolled manner and cold air enters through the ventilation device in case of power failure or in special winter conditions.

Closure of the interior panel

Ideally, the opening of the interior panel faces upwards (avoidance of draught below the interior panel).

Note:

 The ventilation system is always controlled via the control unit.  The system must not be operated in rooms with high dust rate.  The system must not be operated in rooms in which decomposing gases are used.  The system is not suited for drying out buildings.  The ventilation system shall only be started up after the completion of the

construction works.

 The ventilation system is to be closed during the construction works.  Temperature range of application: -20°C to +75°C

2. Operation

2.1 SEC-20 central control unit

The ventilation systems of the SEVi 160 series are operated via the SEC-20 central control unit. The keys desired are activated by a pressure on the membrane keypad. The operating condition, the operating mode selected and the fan stage are indicated by a blue LED top left on the corresponding keypad.

1 Device On/Off:

2 Selection of the fan stage:

3 Acknowledgement/ filter change:

4 Operation in pairs:

5 Permanent intensive brief ventilation operation:

Snooze function:

When the device is switched off, the fan continues to run for a short period of time.

If this key is pressed repeatedly, the fan stages 1 – 4 are run through. The fan stage currently set is shown in the LED display (6).

The end of the maintenance interval for the dust filter is signalized by the LED. The display will be reset if the key is pressed for 5 seconds after the filter change.

Heat recovery mode, normal operating condition in the fan stages 1 – 4.

If this key is pressed, the ventilation system jumps to a permanent intensive brief ventilation mode which allows the ventilation of a room without opening the windows. For this purpose, stage 4 is set automatically.

The control unit is provided with a snooze function by means of which the system can be started with a delay of 60 minutes.

 Set the desired operating mode

and fan stage.

 Keep the keys 3 and 5 pressed

for at least 3 sec. (press key 3 first) ->only the LED of the operating mode set (4 or 5) is lit.

 Press the keys (2), (4) or (5) to

terminate the snooze phase prematurely.

2.2.1 Determining the device type when using SEC-Basic

The SEC-Basic offers the possibility to connect different device types of the SEVi series with different configurations. Depending on the device type, various programmes are implemented in the software. They are described in the following.

Currently, three different configurations are available. To select them, the keys (4) “Alternating operation” and (2) “Fan stage” are to be pressed simultaneously for ca. 5 seconds.

Then, the LED display (6) flashes (see Table). To change the configuration, the key (2) “Fan stage” is pressed to select another

configuration (the corresponding LEDs flash). You can exit the selection mode by keeping the keys (4) “Alternating operation” and (2) “Fan

stage” pressed again for ca. 5 seconds.

Note: The configurations 4 to 7 (indicated by the LED 4 or LED 1+2, 1+2+3, 1+2+3+4)

are reserved for later assignment!

2.2.2 Determining the device type when using SEC-20-BF

The central control unit SEC-20-BF can be used for operating the fans of the SEVi 200 and SEVi 160 series. Moreover, the SEVi 160DUO MINI (available from autumn 2016) can be operated by using the SEC-20-BF.In addition to this, the central control unit can also be used as a humidity sensor.

Determining the device type- The SEC-20-BF offers the possibility to connect different device types of the SEVi series with different configurations. Depending on the device type, various programmes are implemented in the software. They are described in the following.

To select them, the keys (4) “Alternating operation” and (2) “Fan stage” are to be pressed simultaneously for ca. 5 seconds.

Then, the LED display (6) flashes (see Table). To change the configuration, the key (2) “Fan stage” is pressed to

select another configuration (the corresponding LEDs flash). You can exit the selection mode by keeping the keys (4)

“Alternating operation” and (2) “Fan stage” pressed again for ca. 5 seconds.

To activate the humidity control or to set another humidity threshold, the following steps are to be taken:

Keep the “Alternating operation”and “Filter change” keys pressed for 5 seconds. The

control unit changes to the activate /deactivate mode.

The statuscurrently set is indicated by the LED of the fan stages (see Table).

If the “Fan stage” key is pressed, the desired

status of the humidity control can be selected.

If the “Alternating operation” and “Filter change” keys are pressed anew for at least

5 seconds, the setting selected will be stored. Afterwards, the control unit returns to normal operation.

Note to humidity control:

In the activated mode of the humidity control, the room humidity is continuously measured. If the value which has been set for the humidity threshold is exceeded, the fan stage of the fans connected is increased by one stage until fan stage4 is reached. The stages are gradually increased at 15-minute intervals.

If the value measured is lower than the humidity threshold set (minus a hysteresis of about 5%), the fan stage is decreased gradually again down to stage 1.

The manual change of the fan stage is still possible. However, the manual setting will be corrected at 15-minute intervals if the humidity control is switched on. Delivery status: configuration 1, humidity control off
