1. Control panel
3. Start-up
The control panel must be mounted on an interior wall that
is centrally located in the home.
Since the control panel at the same time functions as a
room thermostat, it is important to observe the following:
The first time the system is started, the control panel display will show: “Choose language”.
Click “Next” to switch between Danish, English, German
and French. Press “Enter” when the desired language is
shown in the display. The control panel will now load the
current program version in the selected language.
• Do not expose the control panel to direct sunlight.
• Do not place the control panel on an outer wall.
• Do not recess the control panel in the wall
• Do not place the control panel over a heat source.
A lamp close to the control panel can affect the light
sensor so that the control panel will not regulate the light
intensity as intended.
On the front of the control panel in the ring there are 7
keys that are used to operate the panel. The function of
the keys changes depending on the menu selected. (More
information is available under Operation).
There is an infrared movement sensor located under the
glass screen. Simply by moving your hand past the control panel you can bring up the menu for daily operating
options. (This function can be turned off: See under Main
menu/Display/Menu item 5).
The following are located at the bottom of the control
panel:
1: SD card
2: Room sensor
3: Light sensor
4: Mini USB port for connection to computer
The display will show:
• Updating model (loading the current model)
• Wait 1.5 minutes (It takes approximately 1.5 minutes to
load the current version)
• Language load (91)
• Language OK
• Menu load (84)
• Menu OK
• Icon load (369)
• Menu OK
• Reset to default
• Restarting……..
• Optima 300 UK
Then the display will then change to:
• The Genvex logo
• Optima 300 UK
• Version number
D (Control panel): X.X
C (Main board): X.X
Finally, the display changes to daily operation and the
system is now in operation with the factory setting which is
only a basic setting.
1: The removable SD card contains all the control models
and versions that make the control panel compatible with
older versions. The SD card also contains all the languages, menus, help texts, symbols and collected data logs.
During the start-up procedure, the current versions are
installed in the control panel so that the control can function without the SD card. However, the help texts will not
appear in the display and the data logs will not be saved.
4: In order for a computer to read the data logs, the Genvex data logger program must be installed.
The system is now ready to be adjusted with the most
optimal air flows and the operational desires and demands
for the home in question, e.g. weekly operation, temperatures etc. to achieve the most effective utilisation and
operation of the system.
2. Installation

0
The relay is off
1
The relay is on when the system is running. This can e.g. be used
to open and close the fresh air damper and the exhaust air damper
2
The relay is on when extra heat is required or when the circulating
pump should run when heating with water after heating is required
3
The relay is on when the alarm “Change filter” is active. This can be
used to activate an external alarm
4
The relay is on when extra cooling is required. This function is used
if a preheater is also fitted to the system

The outdoor temperature, sensor T9, is lower than the value
configured in item 26 (frost protection temperature, typically set at
5 °C).
The outdoor temperature, sensor T9, is more than 1° above
the temperature configured in item 1 and 1 ° above the current
room temperature
The relay is on when the temperature in the bedroom is 1 ° higher
as the temperature set in item 40.
Setting option: between 0 and 5.
Factory setting: 0.
12
28 - System stop
Here you choose if it should be possible to stop the system by pressing the key for speed (K1) in the operating
menu for 3-4 seconds. If the set point is OFF, the system
cannot be turned off.
Setting option: ON/OFF.
Factory setting: OFF.
29 - Stop defrosting
As default the defrosting period ends when the evaporator
has reached a temperature of 5 °C. It may be necessary
to change this temperature to a higher value under special
operating conditions where the evaporator is not completely defrosted.
Setting option: between 0 and 15 °C.
Factory setting: 5 °C.
Please note: It is not recommended to configure the item
without expert advice.
30 - Compressor start/stop
The default temperature difference between start/stop
compressor is ± 0.4°. It is recommended to change the
temperature difference under special operating conditions.
Setting option: between 0.1 and 1.0 °.
Factory setting: 0.4°.
Please note: It is not recommended to configure the item
without expert advice.
31 - Constant ON
If the other heating system of the home is not connected
to the heat pump system, the other heating system, e.g.
furnace, can stop the heat pump so that the heat pump
system with heat exchanger only blows preheated air
into all rooms. This will cause increasing problems with
draught as the temperature falls outside. Systems without
heat exchangers will blow fresh air directly in. Configuring
the set point to ON will disconnect the room sensor. The
heat pump will always operate and blow in warm air when
the fresh air temperature is below the temperature configured in item 32. If the set point is configured to OFF, the
room sensor will regulate the heat pump regardless of the
fresh air temperature.
Setting option: ON/OFF.
Factory setting: OFF.
Subject to technical modifications of Optima 300
32 - Constant
If constant ON is selected in item 31, the desired fresh air
temperature can be set.
Setting option: between 0 and 10 °C.
Factory setting: 5 °C.
33 - Reduction
For very low fresh air temperatures, lowering the supply
air flow is recommended in order to improve the operating
conditions of the heat pump and to also achieve a higher
supply air temperature, even though the same air flow will
be extracted. If the set point is configured to ON, the supply air flow will be lowered when the fresh air temperature
falls below the temperature configured.
If the set point is configured to OFF, there will be no reduction of the supply air flow. This configuration applies when
a preheater is installed in the fresh air side. If a furnace is
installed in the home, this setting should be used with care.
Setting option: ON/OFF.
Factory setting: OFF.
34 - Reduced supply air flow
When the set point is configured to ON in item 33, it is recommended that the fresh air temperature is set to -10 °C.
The set point can be configured between -15 and 0°C.
Setting option: between -15 and 0 °C.
Factory setting: -10 °C.
35 - Supply air flow
When the set point is configured to ON in item 33, it is
recommended to configure the reduced supply air flow to
20 % under the value configured in item 11.
Setting option: between 0 and 100 %.
Factory setting: 50 %.
36 - Restriction of cooling
In order to prevent the system from beginning to cool in
winter, regardless of the room temperature, the fresh air
temperature can be configured to the temperature desired
before the cooling function engages. It is recommended
that the temperature is configured to at least 15 °C.
Setting option: between 0 and 20 °C.
Factory setting: 15 °C.
37 - After heating
If an after heater is fitted to the system, you can decide
when you want the after heater to operate.
If the set point is configured to OFF, the after heater will
not work, even if required. If the set point is set to ON, the
after heater will engage as required. It configures itself
according to the temperature set in item 1 minus 1 °.
Setting option: ON/OFF.
Factory setting: OFF.
38 - Extra electrical preheating ON
If an electrical preheater with several levels over the extra
relay circuit board is fitted to the system, the set point
must be configured to ON. If there is no extra relay circuit
board, the set point must be configured to OFF.
Setting option: ON/OFF.
Factory setting: OFF.
39 - Extra electrical preheating
If the extra electrical preheating is set to ON in item 38,
the set point must be configured to the desired fresh air
temperature at which the electrical preheater should heat
the fresh air before the unit.
Setting option: between -15 and 0 °C.
Factory setting: -10 °C.
40 - Bedroom
If a lower temperature is desired in the bedroom or in any
other room than the value configured in item 1 in the User
menu, there is an option to fit extra dampers between the
supply air duct and the duct connection for the bedroom and
control the temperature in the room in question by a room
sensor (T9) by configuring the set point to 6 in item 27.
Setting option: between 10 and 25 °C.
Factory setting: 20 °C.

5. Function
5.2 Extra capacity
Electrical after heating
If the heat requirement exceeds the capacity of the unit,
the electrical after heating (additional equipment) can be
configured to ON in the main menu by the shortcut key.
5.1 Controlling Optima 300
Regulation of room temperature
The room temperature is controlled by the room sensor
T2, which is fitted in the control panel.
If a temperature of e.g. 21 °C has been configured, the
compressor will start when the room temperature falls to
20.6 °C. The compressor will stop when it has heated up
the room temperature to 21.4 °C.
If the compressor cannot maintain the room temperature,
the motor-operated valve (systems with water after heaters) will begin to regulate (PI regulation) when the room
temperature has fallen to 20 °C.
For systems with an electrical after heater divided into up
to 4 levels, the first level will engage when the room temperature has fallen to 20 °C.
If the regulation time is set to e.g. 3 minutes, the room
sensor will measure after 3 minutes whether the room
temperature is now above or below 20 °C.
Level 2 will engage if the temperature is still below 20 °C.
When the room temperature at some point reaches ,
the electrical heat levels will begin to disconnect at 3 minute intervals.
5.3 Operating reliability
High pressure switch
In order to protect the compressor from exceeding its
range of application, a high pressure switch is built in that
will disconnect when the pressure becomes too high.
Activate the red reset button on the pressure switch when
the cause of the fault has been established.
Overriding the supply air fan
If the supply air temperature exceeds 45 °C, the speed
of the supply air fan will begin to increase. The supply air
temperature will be maintained at 45 °C, if possible.
Overriding the extract air fan
If the exhaust air temperature for cooling exceeds 45 °C,
and the speed of the extract air at level 3 is not set to 100
%, the extract air fan speed will begin to increase.
The exhaust air temperature will be maintained at 45 °C,
if possible.
When the cooling (from +3 to +10 °C) starts, the supply
and extract air fans engage at speed 3 and the refrigerant valve MA 7 opens so that the condenser on the supply side functions as an evaporator and the evaporator on
the extract side as a condenser.
When the room temperature has fallen 1 °C, the compressor stops and the fans return to normal operation. The
refrigerant valve MA 7 does not close until the bypass
function is closed.
If an extra refrigerant device is fitted to the system, this
will engage when the room temperature is 2 °C higher
than start cooling. Systems with an electrical preheater will
regulate in the same way as an electrical after heater.
Defrosting
The system begins defrosting when the difference between the temperature before the evaporator and the
temperature of the evaporator becomes too big, which
occurs when ice forms on the evaporator.
The solenoid valve MA 4 opens, the supply air fan and
the electrical heaters stop until the ice has melted and
the evaporator has reached a temperature of about 5 °C.
Then the solenoid valve closes again and the supply air
fan and the electrical heating coils start again.

6. Maintenance
Follow the following instructions to achieve optimal
performance:
Before opening the unit,
turn off the power/pull out the plug and wait
until the fans have stopped completely.
A couple of days after the primary installation check that
the condensation outlet is working.
Environmental requirements
When repairing or dismantling the unit, statutory environmental regulations must be observed regarding
recycling and destruction of various materials.
6.1 Unit
Filters
When the alarm “Change filter” flashes in the control panel
display, the filters must be changed. Stop the system by
the circuit breaker of the unit or by the circuit breaker on
the terminal board. Open the front cover/filter drawers and
remove the filters. After having changed the filters, reset
the filter timer. The time interval for cleaning/changing the
filters can be adjusted in the operating menu.
There is a danger of cuts from sharp discs.
The discs must not be damaged.
Vacuum cleaning or using pressurised air on
the filters is not recommended.
Filter performance may be impaired.
G4 = Standard filter (basic filter class G4)
F5 = Fein filter (fine filter class F5)
F7 = Pollen filter (fine filter class F7)
Condensed water and condensation outlet
The condensation trays must be cleaned of dirt every autumn. Fill the condensation trays with water and check that
the water drains away. If not, the outlets must be cleaned.
Check that the evaporator discs are also clean.
Heat exchanger
Inspect the heat exchanger every 3 years. If it is dirty,
remove it and wash it in warm water with soap and rinse
with a hand shower.
Fans
Inspect the fans for dirt in the fan wheels every 3 years.
Remove the front cover from the unit. Clean the fans with
a brush, a bottle cleaner or a paint brush.
Make sure that the counterbalancing weights on the fan
wheels are not removed, as this will lead to disequilibrium
and cause a higher level of noise and also wear to the fans.
Supply air and extract air valves
Clean the valves by drying with a dry cloth.
Make sure that the valves do not turn around, causing a
change in the air flow.
6.2 Alarms (error messages)
Filter timer
The control has a filter timer in order to ensure that the filters are changed and optimal performance is maintained.
When the timer reaches the configured value, the alarm
“Change filter” will flash in the display until the filters have
been changed. After having changed the filters, press the
key for the filter symbol until the exclamation mark disappears and the system returns to normal operation.
Data error
This error message will appear if no communication is
possible between the display and the control. Check that
the cable connection is correct on terminals 21 to 24.

Frost protection error
This error message will be displayed if a water after heater
is fitted to the system and the temperature of the water
after heater is too low, causing a danger of frost burst. The
control will stop the system and open the motor-operated
valve to keep the heater warm.
Pressure switch error
When the high pressure switch disengages, the message
“Pressure switch” will appear in the display until the red
reset key of the pressure switch is activated.
6.3 Dismantling/taking the system out
of service
The following must be performed:
The power supply, i.e. the electric cables, must be disconnected. Disconnect the condensation outlet and power
cables for any after heater/preheater. Disconnect cables
for the control panel and demount ducts.
If the system should to be taken out of service, the ducts
must be demounted to avoid condensed water in the system and in the ducts.
Close all supply air and extract air valves.

7. Troubleshooting
7.1 High pressure switch
The high pressure switch protects the heat pump from
excessive pressure in the refrigerant circuit. In the event of
disturbances, the high pressure switch will stop the compressor. The system will restart when the high pressure
switch is reset manually.
Before unscrewing the front cover, turn off the power to
the system.
Take off the front cover by removing the screws.
7.3 Error on air side
No supply air to the living rooms
Error possibility:
• The fresh air filter is blocked by dirt and
