1. Mounting Design
1.1 Installation of the control panel
The control panel is designed to be mounted onto a at
wall.
1.2 Mounting
Find the location on the wall where you will x the control
panel and mark the screw-hole positions. A min. of four
screws must be used, the two bottommost and the two
topmost.
Mandatory Screw Mandatory Screw

Hold the wall frame against the wall and mark the
screw-hole positions. Drilling of holes, hole size and the
corresponding screws for xing the panel depend on the
wall material.
Place the control panel in the xtures and tilt it in against
the wall. The four support points in the corner of the
display must touch the wall to keep the display stable.

Underneath the control panel there is an access for the:
A: Terminal block. Connection to main circuit board
A low-current cable 8 x 0.25 mm2 must be attached
between the unit and the control panel. 50 m is the
maximum cable length. The voltage drop for cable
lengths over 50 m is too high and can result in unreliable
operation.
How to mount the wall xture:
First screw the xture securely onto the at wall and pass
the cable up from below.
Connect the low-current cable to the terminal block. Check
that the cable is connected to the same numbers at both
ends. (Between the control panel and the main circuit
board in the unit.)
Next clip the control panel to the wall xture by guiding
it down from above, slightly slanting out at the bottom.
Finish by pressing in at the bottom so that it sits at
against the wall. For demounting: pull the control panel a
little out at the bottom and lift up.

2. Mounting Opus
2.1 Installation of the control panel
The control panel is designed to be tted in the opening of
an Opus type plug socket.
2.2 Mounting
Find the location where the control panel is to be placed
and connect the lead rst then click the control panel in
place.
A low-current cable 8 x 0.25 mm2 must be attached
between the unit and the control panel. 50 m is the
maximum cable length. The voltage drop for cable
lengths over 50 m is too high and can result in unreliable
operation.
Check that the cable is connected to the same numbers at
both ends. (Between the control panel and the main circuit
board in the unit.)
The button to the left of the control panel is B3 and the
button on the right is B5. B4, which we know from the
Design control panel is, in the case of Opus, just used to
hold both buttons down, i.e. B3 and B5 together.
3. Operation
All Genvex GE/S Energy and GEU residential ventilation
units can be operated with the Optima 100 control.
The Optima 100 control has the following settings:
Ventilator speed, lter alarm, bypass ON/OFF and
electrical heating ON/OFF.
The control unit is supplied with factory set settings that
enable the unit to be operated without initially having to
change the settings. The factory settings are only basic
settings, which can be changed to suit the operational
requirements and needs of the building, so that the system
can be optimally used and operated.
3.1 Use and changing of the settings
Optima 100 Design is operated via the B3, B4 and B5
buttons. Optima 100 Opus is operated via the B3 and B5
buttons. With Opus the B4 button enables the B3 and
B5 buttons to be held down at the same time. The button
combinations that need to be used to change the ventilator
speed, reset the lter alarm and switch on/off the bypass
and/or electrical heating are described below.

3.2 Ventilator Speed
Both ventilators can be set independently of each other,
so that the airow at the inlet and outlet are equal, which
results in optimal operation. Commissioning of the unit
must be carried out using technical equipment for and
may be done without the use of a main regulating damper.
It is not advised to set the airow without expert help and
guidance. Incorrect settings can result in increased energy
use.
You must manually select the ventilation unit’s operating
level. You can select this with a short press of the button
B3.
Choose the ventilation speed:
Level 0 inlet/outlet airow: LEDs off –
Standby – cannot be set via the display
Level 1 inlet/outlet airow: LED D1 on –
Default 25% (can be changed, see below)
Level 2 inlet/outlet airow: LED D2 on –
Default 50% (can be changed, see below)
Level 3 inlet/outlet airow: LED D3 on –
Default 75% (can be changed, see below)
Level 4 inlet/outlet airow: LED D4 on –
Always operated at 100% and cannot be set
By default the system is always operating. If the unit is to
be set to Standby, it can only be done via a data logger.
Alternatively, the unit can be switched off at the main
switch.
The procedure for setting the ventilator speed to level
1, 2 and 3 is described below. If no button is activated
within 100 seconds in the set-up menu, the control system
automatically returns to the main display.

3.3 Filteralarm
A built-in lter timer measures the amount of time the unit
has operated since the last lter replacement.
The lter timer can be set between 1-6, which corresponds
with 1-6 months. It is recommended to initially set the lter
timer to 3, corresponding to 3 months.
If the lters become too dirty during the set period, you
can set the lter timer to a lower number of months.
On the other hand, if the lters do not require replacement
at the end of the set period, you can set the lter timer to a
higher number of months.
When the lter timer reaches the set period for a lter
change, LED D5 will begin to ash. When the lters are
changed, the alarm is reset by holding button B4 down for
more than 10 seconds, until LED D5 switches off.
The lter timer is set as described below.

NB: If there is a lter alarm, the lter timer
cannot be set. The lter timer must be reset
rst, before, it can be set again.
3.4. Bypass
Systems that are supplied with a bypass can operate in a
so-called summertime mode. The outlet air is let outside
the heat recovery circuit in the unit via a valve, so that
there is no heat recovery. The temperature of the air that
is let into the house is, thus, not heated, but corresponds
with the temperature of the air outside.
The bypass function must be manually activated via the
display. This is done as per the following:
Bypass ON:
Do a short press on button B5, so LED D5 stays on.
Bypass OFF:
If LED D5 is constantly on, do a short press on button
B5 until D5 turns off. Bypass is OFF, if LED D5 is not
constantly on.
3.5 Electrical Heating
Electrical heating can either be accomplished by a pre-
heating or post-heating element.
A pre-heating element ensures that the heat recovery
circuit does not freeze with very low outdoor air
temperatures.
A post-heating element further heats the inlet air after
it has been heated via the heat recovery process in the
system.
The heating element must be activated manually via the
display. This is done as per the following:
To activate the menu, hold the button B5 down for more
than 10 seconds, until LED D1 begins to ash or the LEDs
D1/D2 ash at the same time.
Electrical heating ON:
LEDs D1/D2 ash at the same time
Electrical heating OFF:
LED D1 ashes
Press button B5 for a short period to change between ON
and OFF.
Press button B4 to return to the main menu.
3.6 Restoring the factory settings
If the set points that are installed result in the system not
operating as expected, and the cause cannot be found,
the factory settings can be restored as follows:
During start-up of the system hold B4 down so that all
ve LEDs are ashing. As soon as all ve LEDs stay
constantly on, the button B4 can be released, and the
system’s factory settings are restored.

Bypass:
Bypass is controlled manually by button B3.
5. Maintenance
For any system controlled by Optima 100, e.g. the Energy
range, you must check if LED D5 is constantly lit or if it
ashes. If it ashes, it means that the lters in the unit
must be changed.
For optimal operation, please observe the following points:
Before opening the unit, turn off the power/
unplug the unit and wait until the ventilators
are completely still.
After the unit has been installed and operating for a couple
of days, it should be checked if the condensation outlet is
functioning.
Environmental requirements:
If icing occurs or if the unit is to be demounted, the
relevant environmental requirements must be followed
in association with recycling and disposal of the various
materials according to the regulatory requirements.
5.1 Parts
Filters:
When LED D5 for the lters in the display is ashing on
the control panel, the lters need to be replaced.
The unit is stopped via the main switch for the system or
via the data-logger. The lters are replaced and the lter
timer is reset. If desired, change the lter-replace time
period in the menu.
It is not recommended to vacuum or use
air pressure on the lter, as these will
compromise the ltering capability.
Cutting hazard: The ns have sharp edges.
The ns must not be damaged.
G4 = Standard Filter (Coarse lter class G4)
F5 = Fine Filter (Fine lter class F5)
F7 = Pollen Filter (Fine lter class F7)
Condensate and condensation outlet:
The condensation outlet must be checked for blockages
and the water trap must be checked for water in
association with changing lters before autumn begins.
Pour 1 liter of water in the condensation water tray and
see if the water drains freely. If the condensation outlet
does not work, there is a risk of water damage in the
building.
Ventilators:
Remember to turn off the power before inspecting the
unit!!
The fan impellers in the ventilator should be checked for
dirt and contaminants every year.
Demount the front cover on the unit. Clean the ventilators
with a scrubbing brush, bottle brush or duster. NB. Do not
remove the balancing weights on the ventilator impellers
otherwise this will cause imbalance and result in noisy
operation and wear of the ventilators.
Inlet and outlet air valves:
The valves are to be cleaned using a dry cloth. Ensure
that the valve does not rotate as this will alter the airow.
Service:
If you are unable to maintain/service your system, you
can make a service agreement with the Genvex service
department. If there is a fault with the system, please
contact the Genvex service department.
5.2 Alarms
Filter timer:
The control system has a lter timer to ensure the lters
are replaced regularly and the unit operates optimally. At
the time when the lter reaches the set value, LED D5 will
begin to ash in the display until the lters are changed.
5.3 Demounting / taking the system
out of operation
The following is to be done:
The power must be disconnected from the unit, i.e. the
electrical cable is disconnected. Take out the condensation
outlet and electrical cables for any pre or post heating.
Disconnect leads to the panel and dismantle ducts.
If the unit is to be taken out of operation, the ducts must
be dismantled to prevent condensation in the system and
in the ducts. Close all inlet and outlet air valves.
