INSTALLATION
6.1.
OF THE UNIT
Selecting an installation location
WARNING
■
Make sure to provide for adequate measures in order
to prevent that the indoor unit should be used as a
shelter by small animals.
■
Small animals making contact with electrical parts can
cause malfunctions, smoke or fire. Please instruct the
customer to keep the area around the unit clean.
The unit is to be placed in an indoor location that meets the following
requirements:
General
■
Installation shall be done by a licensed technician, the choice of
materials and installations shall comply with local and national
regulations.
■
The equipment is not intended for use in a potentially explosive
environment.
■
There is no danger of fire due to leakage of inflammable gas.
■
If the sound is measured under actual installation conditions, the
measured value will be higher than the sound pressure level
mentioned in the "Unit specifications" on page 27 due to
environmental noise and sound reflections. Choose the
installation location carefully and do not install in a sound
sensitive environment (e.g. living room, bedroom, ...).
■
Be sure that sufficient precautions are taken, in accordance with
relevant local and national regulations, in case of refrigerant
leakage.
Location requirements
■
The installation location is frost-free and indoors.
■
Take care that in the event of a water leak, water can not cause
any damage to the installation space and surroundings.
■
The foundation must be strong enough to support the weight of
both models.
The floor is flat to prevent vibrations and noise generation and to
have sufficient stability especially when the optional domestic
hot water tank is mounted on top of the unit.
■
Volume of installation location
During operation the heat pump module increases the domestic
water temperature by using the indoor stored heat. Typical
installation location for this product is a garage, cellar, technical
room, etc.
To have an optimum unit operation and to prevent a too big
temperature drop in the installation location, take the following
requirements for the installation location into account:
Installation manual
6
■ Minimum volume of the installation room
The heatpump operation stops whenever the indoor ambient
temperature becomes lower than 2°C (this can be adapted
by field setting [7-04]). After that, the electric heater in the
domestic hot water tank module will continue to heat up the
domestic hot water. This is a unit safety that prevents the
installation room to cool down further (preventing that e.g.
water piping in the installation room gets damaged) and
guarantees a sufficient comfort level in the form of sufficient
amount of domestic hot water.
To prevent this safety to occur frequently and to assure the
use of the electric heater as little as possible, the room size
must have a minimum volume (see figure below). All
depends on the outdoor temperature, the temperature
setpoint of the adjacent heated room and the insulation
properties of the walls. The volumes in the figure are valid for
an outdoor temperature of –10°C and a temperature setpoint
of the adjacent heated room of 16°C.
With this room volume, the heatpump can heat up 260 liters
domestic hot water from 10°C to 60°C.

When the installation room size does not match the minimum
requirement volume or if the walls between the installation
room and adjacent heated room have better insulation
properties than a single brick wall, additional heat sources
must be considered.
Examples of heat sources:
- if installed in a basement the ground surrounding the
basement will heat up the installation room temperature
- if installed in a garage, the heat of the cars engine
- natural ventilation via e.g. doors leading to the adjacent
heated rooms
- ventilation connection to a heated room
- other: washing machine, dryer

■ Humidity of the adjacent heated rooms
The room where the unit is installed will cool down.
Depending on the relative humidity temperature in the
adjacent room and the insulation property of the common
walls, condensation could occur on the wall.
■ Installing near a wall or obstacle
When the unit is installed as mentioned in the figure below,
the performance and operation of the unit will be optimum.

If the relative humidity in the adjacent heated room is often
higher than 60% (e.g. bathroom) during the heating season
(when outdoor ambient temperature is lower than 15°C)
condensation could occur on the common walls. Relative
humidity levels of a living room normally do not exceed this
60%.
If this should be the case consider to limit the cool down of
the installation room by considering additional heat sources
(see above remarks).
■
Air blowing out
Depending on the operating conditions and the installation
condition, the cold air blown out at the back of the unit can cause
condensation or heat losses to surroundings.
In this case consider to locally insulate the wall on the unit side,
or install the heat pump module with the cold air blow out to an
(e.g.) outside wall.

INFORMATION
If the unit cannot be installed according to the figure
mentioned in "Installing near a wall or obstacle", consider
to use flexible piping between the unit and the customer
water circuit. This could facilitate possible service jobs
where access to one of the sides is required.
Example: when water piping is situated in the blow out zone of
the unit depending on operating conditions and the water
temperature inside the piping this piping can condens. In this
case consider to insulate the water piping.
Depending on the operating conditions and the installation
condition the cold air blown out at the back of the unit can cause
heatlosses and even freezing up temperatures to e.g. non
insulated water piping located in this cold area! In this case
consider to insulate the water piping.

Refrigerant leak
Check the inside of the unit on refrigerant leakage. If there is a
refrigerant leak, call your local dealer.
Do not touch any refrigerant which has leaked out of refrigerant
piping connections.
This may result in frostbite.
8
Different domestic hot water tank operation modes
To understand the field setting possibilities explained in the following
chapters, understand that different domestic hot water tank operation
modes are possible.
■
■ If the P button is pressed, the heat pump module heats up
the domestic hot water tank as fast as possible to a
predefined setpoint. This means that the inverter compressor
frequency will be higher then in normal operation mode and
that sound level and power consumption can be higher.
This mode might be usefull when exceptional high hot water
consumption depletes all the available domestic hot water
and hot water is required.
Water leak
Check the inside of the unit on water leakage. In case there is a
water leakage close the water inlet and water outlet shut-off
valves and call your local dealer.
9
Power supply voltage
Check the power supply voltage on the local supply panel. The
voltage must correspond to the voltage on the identification label
of the unit.
■ Depending on settings, simultaneous heat pump operation
and booster heater operation can occur.
Once all checks are fulfilled, the unit must be closed, only then can
the unit be powered up. When the power supply to the indoor unit is
turned on, "88" is displayed on the remote controller during its
initialization, which might take up to 30 seconds. During this process
the remote controller can not be operated.
INFORMATION
The unit increases the domestic hot water temperature by
using the indoor stored heat.
The powerful mode might not function properly when the
room ambient temperature is too low.
10.2. Field settings
The unit should be configured by the installer to match the user
demand. Thereto, a number of so called field settings are available.
These field settings are accessible and programmable through the
user interface on the unit.
■
Disinfection operation
■ This mode will disinfect the domestic hot water tank by
periodically heating the domestic water to a high temperature. This can be required for e.g. legionella prevention.
■ This mode is enabled by default.
Each field setting is assigned a 3-digit number or code, for example
[2-01], which is indicated on the user interface display. The first digit
[2] indicates the 'first code' or field setting group. The second and
third digit [013] together indicate the 'second code'.
Refer to the chapter "Detailed description" on page 19 for a
detailed description how to set one or more field settings.
- [0-01] Set point: Disinfection water temperature to be
reached (see figure "[2] Disinfection operation" on page 19).
- [2-00] Operation interval: day of the week at which the
domestic water should be heated.
- [2-01] Status: defines whether the disinfection function is
turned ON (1) or OFF (0).
- [2-02] Start time: time at which the disinfection operation is
started.
- [2-04] Duration: time period defining how long the disinfection
set point temperature should be maintained.
A list of all field settings and default values is given in the "Field
settings table" on page 22. In this list we provided for 2 columns to
register the date and value of altered field settings at variance with
the default value.
A detailed description of each field setting is given under "Detailed
description" on page 19.
NOTICE
Field setting [2] depends on the relevant local and national
regulations.
Before changing these settings, the new values shall be
confirmed by the installer and/or shall be according to the
local and national regulations.
Powerfull operation
Even when the unit is in OFF mode, disinfection operation can
work (depending on field setting [2-03]).
■
Reheat operation
This mode will prevent the domestic hot water from cooling down
lower than a certain temperature. When enabled the unit will
heat up the domestic hot water tank when the reheat minimum
value is reached. This heating will continue until the reheat
maximum temperature is reached.
This means that the unit can heat up continuously and e.g. not
limited to night time operation. This reheat operation is only valid
when schedule timer operation is enabled and not active.
■
Automatic operation
■ This operation mode contains a learning function to predict
the daily hot water consumption. It will calculate and predict
the optimum tank temperature setpoint based on the user
tapping history.
Enabling this operation mode will keep the tank temperature
as low as possible but to a temperature which guarantees a
high comfort level.
■ The advantage of a low tank temperature setpoint are :
- Reduced heatlosses
- Better unit performance, the lower the tank temperature the
better the heat up coefficient of performance (COP).
- Lower electric power consumption
■ Refer to the operation manual for a detailed description.

[1-00] Renewal time for set point calculation
Note that with the function disabled the schedule timer will not
be activated when power returns to the unit after a power supply
failure. Press the pr button to enable the schedule timer again.
The automatic temperature set point calculation is done on a
daily basis. The algorithm calculates for each day of the week an
optimum domestic hot water tank temperature set point. To
calculate this temperature setpoint, the learning function
monitors per 24 hours the domestic water heating demand and
based on this demand calculates the optimum set point for that
specific day of the week.
This field setting contains the starting time for the 24 hours
monitoring period.
This field setting must be set preferably after the main heating
up of the domestic water of the day has finished.
For example: If in schedule timer operation mode the schedule
timer was set from 22 h until 6 h, the renewal time should be set
at 6 h.
■
If the benefit kWh rate power supply is of the type that
power supply is interrupted, then always allow the

[1-01] Minimum automatic temperature set point
If required the minimum temperature set point for the automatic
set point calculation can be adjusted. If, for example,
considerable heatlosses are expected on the field piping
between the hot water tap and the domestic hot water heat
pump, this temperature set point can be usefull.
■
INFORMATION
[1-02] Maximum automatic temperature set point
The maximum temperature that the automatic set point can
reach.
However, if this value is set on a temperature higher than 60°C,
that maximum temperature will only be reached when field

[6] Miscellaneous
[6-00] and [6-01]: The 'DT (temperature difference) for heat pump
domestic water heating mode' field settings determine the
temperatures at which heating of the domestic hot water by the heat
pump will be started (i.e., the heat pump ON temperature) and
stopped (i.e., the heat pump OFF temperature).
When the domestic hot water temperature drops below the heat
pump ON temperature (THP ON), heating of the domestic hot water by
the heat pump will be started. As soon as the domestic hot water
temperature reaches the heat pump OFF temperature (THP OFF) or
the user set point temperature (TU), heating of the domestic hot water
by the heat pump will be stopped.
The heat pump OFF temperature, and the heat pump ON
temperature, and its relation with field settings [6-00] and [6-01] are
explained in the illustration below.
