1. Users guide
Optima 150 comes with a factory setup, which enables an
immediate start of the unit. The factory setup is basic and
must be adjusted to the operational requirements and
demands of the individual home, in order to obtain the
optimum operating benet from the unit.
1.1 Use
Users menu
The value of a menu item is shown when pressing the
key/key combination below. The value may be changed
with the arrows when the key/key combination is held
down simultaneously. The control will return to standard
indication if no buttons have been pressed for app. 15
seconds.
P1: Heat Pump ON/OFF
On this buttom is it possible to change the function
between: standby and automatic operation after
setpoint P3. (Step 0, Step 1).
Step 0: The heat pump is now off and only the
control is active.
Step 1: The heat pump is in operation mode and
drives after setpoint thermostat P3.
P2: Operation for the electrical cartridge
The heat pump comes with an extra electrical
cartridge for heating of the sanitary hot water.
On this buttom is it possible to turn on the the
electrical cartridge if required. By adjusting the
setpoint to 1 the electrical cartridge will turn on
after setpoint P5 (operating thermostat for the
electrical cartridge). The electrical cartridge is not
on if this setpoint it set to 0.
Note! When the ambient temperature is under 8°C
or over 35°C the electrical cartridge will turn on
even if P2 = 0.
P3: Operating thermostat for heatpump
The required sanitary water temperature may be
set between 0 - 55 °C, which is heated up by the
heat pump.
Factory setting: 52°C
Max.. water temperature: 55°C
P5: Operating thermostat for the electrical
cartridge
The sanitary water temperature may be adjusted
between 0 - 65 °C. The electric cartridge solely
heats the top half of the container, while the heat
pump still heats the lower half of the container.
Factory setting: 50°C
Display indication
It is possible to view various temperatures in
the display, by pressing the arrows until the
requesteed temperature is indicated. After
app. 5 seconds, the temperature is shown.
The temperature is shown for app. 30 seconds
until the display returns to standard. Following
temperatures may be indicated:
T5: Ambient temperature
T6: Cooling coil
T7: Sanitary water top
T8: Sanitary water buttom
1.2 Altering the operation data in the
operating menu
Usually, the display shows the water temperature.
Press (arrow up) and (arrow down) simultaneously for
app.10 seconds in order to enter the operating menu. The
display will now show the rst point E0 in the operating
menu. The operating menu will automatically close and
return to the main menu if a button has not been pressed
for 15 sec.
If you wish to scroll through the operating menu, it may
be done by pressing (arrow up) or (arrow down). The
value of a point is shown when pressing (temp button).
The value may be changed with the (arrow up) or (arrow
down) while simultaneously pressing (temp button). The
control will return to standard indication if no buttons have
been pressed for app. 15 seconds.

1.3 Operating menu
E0: Factory setup
If the system does not function as expected, even though
the setpoints have been adjusted, and the cause is
impossible to locate, it is recommended to note down the
settings in the schedule. The setpoint must be adjusted
to 1 and then wait until the control returns to standard
indication. Now all the setpoints have been changed to
the factory setup. It is now possible to start all over and
adjust the setpoints.
Factory setting: 0
E8: Disinfection function ON/OFF
By setting the valve to 1, the electric cartridge will provide
65°C hot water, once a week, in order to disinfect the
tank.
Factory setting: 0
E16: Min. airow
This value shows the minimum speed at which the fan is
permitted to run when operating. Notice that the cooling
system may be overloaded, resulting in a drop out of the
highpressure switch, if the value has been set too high.
The value should not be chosen higher than necessary, in
order to secure a minimal airow through the cooling coil.
Adjust this valve between 0-100%.
Factory setting: 0
E21: TX set
To avoid too high operating pressures in the cooling
system, the system output must be reduced for the
remaining part of the heating period. This parameter
indicates the water temperature at which the reduction
should start. It may be set to 0-55°C.
Factory setting: 50
E23: Tmop
This value indicates the maximum permitted evaporation
temperature. This prevents overloading of the
compressor system at high ambient temperatures.
Adjust this value between 0 - 25°C.
Factory setting: 25
E45: dTair-set
Here it is possible to choose minimum cooling of the air,
while heating the water. The control will adjust the speed
of the fan to make sure the air will be cooled at the exact
temperature chosen. In case the control, due to technical
reasons, needs to cool the air, the value will be controlled
by the automatic function. When requiring a higher fan
speed, the value may be reduced. Remember though, the
fan will run faster, using more energy, if the values are set
too low.
Factory setting: 1

2. Function
2.1 Function description Optima 180
The ow diagram shows the location of the sensors, while
the circuit board shows the relay outputs and the other
outputs for connecting fan and control panel.
Vanvex Lite sanitary hot water heat pump:
Vanvex Lite is an independent sanitary hot water heat
pump to be installed in rooms that are not part of the
living space, e.g. basement rooms.
The only requirement to the room is that the air
temperature stays between 8°C and 35°C.
We recommend basement rooms because even during
the winter heat is supplied from the surrounding soil layer.
Heat pump operation
The control starts the compressor shortly after hot water
has been tapped. The compressor will run until the entire
tank has been heated to the set temperature again.
Usually the heat pump can produce a sufcient amount of
hot tap water covering the needs of a common family.
Water heating:
When hot water is drawn off, the tank will be relled
with cold water at the bottom. A sensor measures the
temperature at the bottom of the tank and starts the
compressor if the temperature has fallen 5°C below
the set temperature. The compressor stops, when the
water has been heated to the set temperature. While
the compressor operates, the fan runs and circulates air
through the cooling coil.
Fan operation:
The operating valve can be adjusted between 0-100%.
2.2 Extra Capacity
If a situation should occur where the heat pump is not
capable of producing enough hot tap water (more people
in the house), an extra electrical cartridge in the container
can be switched on. Doing so, it is possible to heat up
more water. It is possible to set the desired temperature
to which the electrical cartridge should heat up the water.
(Only use the electrical cartridge when needed, as it
uses more energy than the compressor). The electrical
cartridge can be activated manually on the display.
2.3 Operating safety
Highpressure switch:
To prevent the compressor from exceeding its range of
operation, there is an integral high pressure switch, which
interrupts when the pressure is 20 bar in the cooling
unit. Activate the red reset button once the cause of the
error has been identied. When the high pressure switch
interrupts, the red Genvex logo will ash until the reset
button manually or the pressure has fallen to 15 baror the
cause of error has been idened. When the high pressure
switch interrupts, the red light will ash until the reset
button on the pressure switch is activated. In order to
prevent a repetition of a pressure switch error, the water
may be set 2-3 °C lower.
Operation description:
By setting voltage to the system the display will count 5
seconds up after which the control will show the version
number. When this has been done the water temperature
will be shown in the water reservoir (standard indication).
If the water temperature is lower than the setpoint by
the operating thermostat, the compressor and the fan
will turn on. The fan wil start with 30% speed and adjust
the speed until 100% is reached. When the operatigng
temperature (P3) is reached the compressor and the fan
will stopp.
Ambient temperature:
If the ambient temperature is under 8°C the compressor
and the fan will stopp and rst restart when the ambient
temperature is 9°C (however there will go op to 30 minuts
before the compressor will restart). When the ambient
temperature is under 8°C the electrical cartridge will
automatically turn on and turn on/off according to the
setpoint at the operatign thermostat (P5). The same
conditions have its effects when the ambient temperature
is over 35°C, hereby the compressor will restart again by
34°C with a delay on the compressor.
Safety breaker
If an error occurs at the electrical cartridge, the safety
breaker trips. Resetting the safety breaker may be done
by breaking the small button in the centre.
(When working on the heat pump, always
make sure that the power supply is
disconnected.
Any work on this unit may only be carried
out by trained personnel!)
2.4 Warnings
Pressure switch error:
When the high pressure switch trips, the red Genvex logo
will ash until the red pressure switch is reset.

3. Maintainance
The following instructions must be followed in order to
ensure optimum operation of the Vanvex:
The power supply to the system must
always be switched off and the fan must
have stopped completely before opening the
Vanvex’s cover.
When the unit has been installed for the rst time make
sure the water connections are checked after a few days
to make sure there are no leaks. Also check that the
condensate drain is not blocked.
Environmental considerations
When the unit is being serviced or its operation is
cancelled, please make sure to follow the guidelines for
recovery and disposal of all materials according to local
procedures and laws.
3.1 Communication box
To allow Optima 150 to communicate with the computer
(data logger), CTS unit, the “Genvex Datalogger”
communication box must be mounted between the
control panel and the computer/CTS unit. The unit is sold
by Genvex.
3.2 Cooling system and fan
Fan:
Maintaining the fan is mainly periodicly cleaning of the
evaporator. Unscrew the top plate. Clean the evaporator
and fan with a suitable brush. Do not remove the
balancing blocks from the impeller, as this will cause
imbalance and with it more noise and fan wear.
Risk of injury from sharp-edged ns! DO
NOT damage these ns!
Condensed water and condensate drain:
When inspecting and cleaning the fan, it is neccesary
to clean the condensate tray for dirt. Fill water in the
condensate tray and check that the water runs out
unhindered. Should this not be the case the drain must
be cleaned. At the same time make sure that the plates of
the evaporators are clean.
3.3 Watercircuit and tank
Safety valve:
The installer has tted a safety valve on the cold water
supply pipe for the hot water tank. This valve is a
protection of the tank against excess pressure when the
sanitary water expands during heating. The non-return
valve, which is tted before the safety valve on the cold
water pipe, prevents the water from owing back into
the cold water pipe. This means that the pressure in the
tank will increase to the maximum pressure permitted by
the safety valve, at which point it will open and allow the
surplus water to escape. If the safety valve did not open,
the tank would burst.
To make sure that the safety valve is working properly,
it should be inspected several times a year. To do this,
press the spring-loaded arm on the safety valve and
see if water comes out of the valve. Damage caused
by a blocked safety valve is not covered by the Genvex
warranty.
Anode:
In order to prevent corrosion of the enamelled hot water
tank, the tank is tted with a magnesium anode at the
middle of the tank. This anode has a life expectancy of
2-5 years according to the water quality. It is nevertheless
important to check that the anode is intact at all times.
This should be done by inspecting the anode every 2
years and replacing it if it is corroded and measures only
6-10 mm in diameter. To inspect the anode, turn off the
power supply to the system and remove the cover. The
hot water tank has to be drained before the anode can
be unscrewed. To do this, turn off the cold water supply ,
attach a hose to the drain valve to ensure the water runs
to the nearest drain. When draining the water from the
tank, turn on a hot water tap to prevent negative pressure
in the tank. When the tank is empty, the anode can be
unscrewed and inspected. When the anode has been
tted again, close the drain cock and turn the valve water
supply back on to ll the tank with water. When the tank
is full and the cover back on, the power supply can be
switched on again.
3.4 Demounting / putting the unit out
of service
The following actions must be taken:
Disconnect the power supply to the unit and disconnect
other connections (demount the water and heat pipe and
drain the tank). Shutoff the fresh water supply valve and
connect a drain hose to the drain valve in order to drain
the water.

4. Fault nding
The heat pump is equipped with the following safety
devices:
4.1 High pressure switch:
The high pressure switch protects the heat pump against
too high pressure in the cooling circuit.
In case of interruptions (too high pressure) the red light in
the control panel will ash and the high pressure switch
will stop the heat pump. The red light lights. Restart
the equipment by manually resetting the high pressure
switch.
For reaching the manually resetting, look between the
lamella on the top.
If the aggregate stops more times repeatedly you should
call the service.
4.2 Safety breaker for electrical
cartridge
The safety breaker protects the equipment against
overheating during heating with the electrical cartridge.
The safety breaker is mounted on the heater. If the
adjusted value (90°) is exceeded the electrical cartridge
will disconnect. It can be reconnected when the
temperature is below 90°. To do this, the power to the
equipment must be off, front door dismantled. The reset
button can now be pressed.
4.3 The heat pump will not run!
Please test if:
● power is connected?
● power is turned on at the wall plug?
● the heat pump is disconnected through the
temperaturecontrol?
● the temperature of the sanitary water > 55° C
● is the high pressure switch disconnected?
● is the cooling coil dirty?
If this does not help locating the error, please contact
your local installer or service contractor.
