After commissioning, the following values apply
for the ventilation system:
Fan level 0: Both fans are switched off
Fan level 1:
Approx. 30% below the nominal air quantity
Fan level 2: Nominal air quantity
Fan level 3:
Approx. 30% above the nominal air quantity
Since the nominal air quantity for the building is
set using fan level 2, it is not necessary to set a
time period for fan level 2. This is always active
when no other fan level has been programmed.
Therefore, only the settings for levels 0, 1 and 3
are available in the menus.
Creating the weekly programme:
The fan levels can be set for each day of the
week. It is thus possible to set reduced venti-
lation during the nights and the weekends or to
programme a short period of high-power venti-
lation prior to the commencement of business
hours.
Inorderto access theweeklyprogramme, press
the "Enter" button. Select "Wochenprogramme"
using the arrow buttons and confirm this with
the "Enter" button.
Use "Enter" to select and confirm values; use
the arrow buttons to change values.
The programme for one day of the week can be
copied to the following day.
The example on the right illustrates the set-
ting for Monday (Montag). The settings for
Tuesday (Dienstag), Wednesday (Mittwoch),
Thursday (Donnerstag), Friday (Freitag),
Saturday (Samstag) to Sunday (Sonntag) are
made in the same way.

Operating, Maintenance, Commissioning Page 11
Programming during the night:
A time period of 0°° to 24°° hours is available for each day of the week.
0.°° 24.°°
12.°° 18.°°
6.°°
Each fan level can be set once for each timeframe. If you wish to set a specific fan level
for throughout the night, the applicable time period is always from evening until morning
on the same day.
E.g.: Monday, from 18:00 to 06:00
0.°° 24.°°
12.°° 18.°°

Faults/messages
If faults occur or messages are issued, they are displayed instead of the date and time
and the background illumination of the display flashes.
"Störung Venti." (Fan fault)
This error message appears if a fault occurs on one of the two fans. For safety reasons,
the second fan is also deactivated.
Please contact your authorised technician.
"Filterwechsel" (Filter change)
The 3-stage timer includes a background counter that monitors the service life of the fil-
ters and prompts you to change them when necessary.

Operating, Maintenance, Commissioning Page 13
Maintenance
Maintenance of your comfort ventilation system is mainly limited to changing the coarse particle
filters and the fine particle air filter in the ventilation unit.
The operating panel shows when a coarse particle filter needs to be changed. However, this is
not shown for the fine particle air filter, which needs to be changed at a fixed time each year; for
example, at the start of the heating period.
The fine particle air filter needs to be changed once or twice each year, depending on the filter
type and environment. You should also make a note of the date on which the filter change was
carried out.
The flow capacity and acoustics of the ventilation unit are affected by the amount of dirt in the
filters. We therefore recommend that filters are changed regularly. No tools are required.
Caution: Possible damage to the unit resulting from dust and contamination. The coar-
se particle filters in the unit not only improve your air quality, but also protect the entire
ventilation system. The system must not be operated without a coarse particle filter.
Note: The filter should be changed within 2-4 weeks of the 'Filter change' message
appearing..
Safety notes for filter changes
Caution: The filter change intervals are only valid for a completely run-in system. After
the initial commissioning, the filters can sometimes become very dirty after a relatively
short period of time (construction dust). An error message is not displayed in this case.
Caution: Filters cannot be washed or vacuum cleaned, as this would drastically af-
fect their effectiveness. Contaminated filters must always be replaced with clean filters.
Used filters should be disposed of in the residual waste.
Caution: To ensure that the ventilation unit continues to operate correctly, we recom-
mended that a service is carried out by an authorised technician after two years of
operation (check the fans, clean the air module). Local laws and regulations governing
maintenance intervals must be adhered to.
Changing the filters
Do not switch off the unit or unplug it from the mains as the controller will not detect the change
of filter.
Open the latches for the inspection doors on the top of the unit.
When the inspection doors are opened, the contact switch (4) is activated and the unit swit-
ches off.
To change the coarse particle filter, remove both filter slots
(See the figures on the following page; no. 1 + 2).

Operating, Maintenance, Commissioning
Page 14
Remove the contaminated filter pads.
Insert new filter pads and push the slots back into the openings.
To change the fine particle air filter, remove the filter cartridge by pulling it forwards
(see fig. 3).
Insert new filters in the openings. Please note the direction of insertion (indicated by an
arrow on the fine particle air filter).
Close the inspection doors and fasten the latches.
The contact switch (4) is activated and the unit starts up automatically.
Note the filter change date in the unit data.
Spare filters:
Please order filters from your authorised technician.

Commissioning
Prerequisites for commissioning
The water, air, electrical and mechanical connections for the comfort ventilation unit must
be carried out in accordance with the installation instructions. This particularly applies to
the insulation of the air pipes and the condensation connection.
Caution: The unit must not be operated without complete insulation of the air pipes
(exhaust and outside air) as any condensation could damage the individual unit compo-
nents, such as the electronics or the fans.
Initial commissioning
Warning: Electrically conductive components may cause serious personal injury. Im-
proper working procedures could damage unit components. The initial commissioning
may only be carried out by suitably qualified and authorised technicians.
When the controller is powered on for the first time, it first performs a self-test. (If you are
operating the unit using a 3-stage timer, the version number of the controller appears on
the display when the unit is switched on.)
Fault messages during initial commissioning
Please note that the filters can become clogged very soon after initial commissioning of
the unit as the air can contain high levels of dust (construction dust). An error message
is not displayed in this case. Should abnormal sounds occur or condensation form on the
outside of the unit, please arrange for the entire system to be checked by an authorised
technician.

Operating, Maintenance, Commissioning

Setting the nominal air quantity
Warning: Serious personal injury may result from improper working procedures. The
nominal air quantity may only be set by suitably qualified and authorised technicians.
Before setting the nominal air quantity, the unit must be fully disconnected from the
mains.
Open the latches for the inspection doors at the top of the unit.
Remove the cover guard from the controller unit (a) using a suitable Phillips screwdriver.
The nominal air quantity for the unit is set using DIP switches 5 to 8 on the controller board.
Controller board:
A) FSH switching point
B) DIP switch
C) Room operating panel
D) Total error

Operating, Maintenance, Commissioning Page 17
The nominal air quantity only needs to be set for fan level 2. The air quantity for fan level
1 and fan level 3 is calculated automatically as -30% and +30% respectively.
Example: Nominal air quantity, 80 m³/h, 5=OFF, 6=OFF, 7=OFF, 8=OFF
Setting the fan balance
DIP switches 3 and 4 are used to set a higher air quantity for the supply air fan in compa-
rison to the extract air fan.
Switching point for frost protection heating (FSH)
The FSH switching point can be set between -5°C and 0°C using the potentiometer on
the controller board.
FSH switching point:
Left stop / - 5°C
Right stop / 0°C
