2. GENERAL SAFETY PRECAUTIONS

The precautions listed here are divided into the following four types.
They all cover very important topics, so be sure to follow them
carefully.

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.

Do not touch any switch with wet fingers. Touching a switch
with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.

To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are
50 V DC or less.

When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL
PA RT S

Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.

Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear protective gloves.

WARNING

■ Never directly touch any accidental leaking
refrigerant. This could result in severe wounds caused
by frostbite.

■ Do not touch the refrigerant pipes during and
immediately after operation as the refrigerant pipes
may be hot or cold, depending on the condition of the
refrigerant flowing through the refrigerant piping,
compressor, and other refrigerant cycle parts.

Your hands may suffer burns or frostbite if you touch
the refrigerant pipes. To avoid injury, give the pipes
time to return to normal temperature or, if you must
touch them, be sure to wear proper gloves.

CAUTION

Do not rinse the unit. This may cause electric shocks or
fire.

6. INSTALLATION OF THE UNIT

6.1. 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:

■ 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.

B

B E.g. garage

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.

Where a wall or other obstacle is not according to the figure
mentioned in "Installing near a wall or obstacle", follow the
installation guidelines below.

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.

Exampl

e: 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.

installing of the EKFMHMSAA kit is necessary. Refer to the
manual of that kit.

■ Make sure to check if the speed setting of the pump is set in
position III if the domestic hot water tank module is mounted on
top of the heat pump module.

Connecting the water circuit

Water connections must be made. The location of the water inlet
connection and the water outlet connection on the unit is shown in
the chapter 5.2. "Overview of the domestic hot water tank module" on

page 4.

WARNING

Be careful not to deform the unit
piping by using excessive force when
connecting the piping. Deformation of
the piping can cause the unit to
malfunction. Use two wrenches as
shown in the figure.

Connect the drain pan

During operation and depending on operation conditions the heat pump
module collects condens water in the drain pan at the bottom of the unit.
Make sure to provide a proper drain connection to this drain pan.

CAUTION: Requirements to drain piping

■ The drain piping must be positioned away from any
electrical components.

■ The drainpipe must terminate in a safe, visible position
without forming any risk to persons in the vicinity.

■ All drain pipe work must be installed in a continuously
downward direction and in a frost-free environment. It
must be left open to the atmosphere.

7.2. Precautions when connecting field piping and
regarding insulation

The complete water circuit, inclusive all piping, must be insulated to
reduce loss of heat.

If the indoor ambient temperature is higher than 30°C and the
humidity is higher than RH 80% then the thickness of the insulation
materials should be at least 20 mm in order to avoid condensation on
the surface of the insulation.

If air, moisture or dust gets in the water circuit, problems may occur.
Therefore, always take into account the following when connecting
the water circuit:

■ Use clean pipes only.

■ Hold the pipe end downwards when removing burrs.

■ Cover the pipe end when inserting it through a wall so that no

dust and dirt enter.

■ Use a good thread sealant for the sealing of the connections.

■ When using non-brass metallic piping, make sure to insulate

both materials from each other to prevent galvanic corrosion.

■ Because brass is a soft material, use appropriate tooling for
connecting the water circuit. Inappropriate tooling will cause
damage to the pipes.

Connect the pressure relief valve (field supply) and drain

■ In accordance with relevant local and national regulations, a field
supplied pressure relief valve with an opening pressure of
maximum 10 bar must be connected to the pressure relief valve
connection.

■ Make sure to provide a proper drain for the field supplied
pressure relief valve to avoid any water coming into contact with
electrical parts.

CAUTION: Requirements to discharges

■ Discharge piping, drain valves, etc. must be
positioned away from any electrical components.

■ All discharge pipe work must be installed in a
continuously downward direction and in a frost-free
environment. It must be left open to the atmosphere.

Connection to a benefit kWh rate power supply

Electricity companies throughout the world work hard to provide
reliable electric service at competitive prices and are often authorized
to bill clients at benefit rates. E.g. time-of-use rates, seasonal rates,
Wärmepumpentarif in Germany and Austria, ...

This equipment allows for connection to such benefit rate power
supply delivery systems.

Consult with the electricity company acting as provider at the site
where this equipment is to be installed to know whether it is
appropriate to connect the equipment in one of the benefit kWh rate
power supply delivery systems available, if any.

When the equipment is connected to such benefit kWh rate power
supply, the electricity company is allowed to:

■ interrupt power supply to the equipment for certain periods of
time;

■ demand that the equipment only consumes a limited amount of
electricity during certain periods of time.

The indoor unit is designed to receive an input signal by which the
unit switches into forced off mode. At that moment, the unit
compressor and the heater will not operate.

WARNING
For a benefit kWh rate power supply like illustrated

below as type 1

During the period that the benefit kWh rate is active and
power supply is continuous, then stand-by power
consumption of the inverter PCB is possible.

7 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 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.

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.

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.

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'.

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.

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.

■ Powerfull operation

■ 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.

■ Depending on settings, simultaneous heat pump operation
and booster heater operation can occur.

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.

■ 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.

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.

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.

Detailed description

[0] Different operation modes

■ [0-00] Powerfull operation mode temperature set point

■ [0-01] Disinfection operation mode tempeature set point

■ [0-02] Temperature setpoint: reheat minimum temperature

■ [0-03] Temperature setpoint: reheat maximum temperature

■ [0-04] Reheat function enabled/disabled: defines whether the

reheat operation is turned ON(1) or OFF(0)

[1] Automatic domestic hot water tank temperature set point

calculation

■ [1-00] Renewal time for set point calculation
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.

■ [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.

■ [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
setting [3-02] is set to 1 (ON). If the setting of [3-02] is 0, the
maximum temperature will be 60°C (only heating up by heat
pump) ignoring higher set temperatures.

[2] Disinfection operation

The disinfection function disinfects the domestic hot water tank by
periodically heating the domestic hot water to a specific temperature.

NOTICE

The disinfection function field settings must be configured
by the installer according to local and national regulations.

■ [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.

■ [2-03] Status: defines whether the disinfection function is turned
ON(1) or OFF(0) during standby operation. If for example, during
holiday the customer puts the unit in stand-by mode by pressing
the Y button but still wants the disinfection mode to be active,
the setting of [2-03] must be ON(1).

■ [2-04] Interval: time period defining how long the disinfection
temperature set point should be maintained.

[3] Miscellaneous

■ [3-00] Auto restart
When power returns after a power supply failure, the auto restart

function reapplies the user interface settings at the time of the
power supply failure.

INFORMATION

It is therefore recommended to leave the auto restart
function enabled.

If auto restart is disabled after a power supply failure, the system
will restart in OFF-mode. Press the v button to start heating
up the water again.

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.

INFORMATION

If the benefit kWh rate power supply is of the type that
power supply is interrupted, then always allow the
auto restart function.

■ [3-01] User permission level
The remote controller can be programmed to make certain

buttons and functions unavailable for the user. There are 2
permission levels defined.

The following table shows which functions are accessable with
permission level 2 and with permission level 3.

■ [3-02] Status: defines whether temperatures above 60°C can be
selected (1) or not (0).

INFORMATION

■ The maximum domestic hot water tank
temperature by heat pump operation is limited to
60°C. A higher temperature set point is only
possible by electric booster heater operation.

■ When this field setting is not activated, the
booster heater will still work if the ambient
temperature drops below the value set in [7-04].
This is the backup mode of the domestic hot
water heat pump.

■ [3-03] Status: defines whether the heat up can continue (1) or
not (0) when the requested temperature set point is not reached
during the programmed schedule timer operation. The p icon is
blinking in case the heat up can not continue ([3-03]=0).

In case the reheat function is enabled, the p icon will stop
blinking when the reheat operation has finished.

[4] Miscellaneous

■ [4-03] Simultanuous operation of booster heater and heatpump

■ [4-03]=0 Simultanuous operation of the electric booster

heater and heat pump is not allowed.

■ [4-03]=1 Simultanuous operation of the booster heater and

heat pump is only allowed during quiet mode. During quiet
operation the heat pump operation sound is reduced by
reducing the compressor frequency. This influences the
heating capacity and increases the heat up cycle time.
If required the electric booster heater can assist to heat up
the domestic hot water tank to shorten the heat up cycle
time.

■ [4-03]=2 Simultanuous operation of the booster heater and

heat pump is only allowed during powerful operation mode.
The powerful operation mode is considered as an
exceptional operation mode. If required during powerful
operation the electric booster heater can assist to heat up the
domestic hot water tank.

■ [4-03]=3 Allows the simultanuous operation of electric

booster heater and heat pump during quiet and powerful
operation.

[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 (T

), heating of the domestic hot water by

HP ON

the heat pump will be started. As soon as the domestic hot water
temperature reaches the heat pump OFF temperature (T

HP 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

WARNING

If the high water temperature can be a potential risk for
human injuries, a mixing valve (field supply) shall be
installed at the hot water outlet connection of the domestic
hot water tank. This mixing valve shall secure that the hot
water temperature at the hot water tap never rise above a
set maximum value. This maximum allowable hot water
temperature shall be selected according to local and
national regulations.

■ [7-03] Not applicable

■ [7-04] T-ambient adaption: this field setting allows to adapt the

minimum allowed temperature in the installation room for heat
pump operation.

WARNING

It is very important that this value is not set to a
temperature that can cause damage to the installation
room!

It must be set in a way so that condensation does not
occur on the cold walls of the adjacent heated room.

[8] Automatic set point calculation

■ [8-00] Set point (weekdays): starting temperature for automatic
set point calculation during weekdays.

■ [8-01] Set point (week-end): starting temperature for automatic
set point calculation during week-end.

NOTICE

Because the domestic hot water demand is not known
from the start and to avoid comfort problems this
should be set to the customer estimated consumption
set point.

■ [8-02] Initial city water temperature
To be able to start calculation of the automatic set point, [8-02]

should be set to the current city water temperature when the unit
is started. The outdoor temperature will influence the city water
temperature, making it colder during winter time and warmer
during summer time.

■ [8-03] Reset demand: when this field setting is set to 1 and
power is reset, the automatic set point calculation is reset and
calculation will start all over again. This setting is used when
there is a permanent change in the user domestic hot water
consumption pattern.

When power is reset, initialisation is executed and this field
setting will automatically be set to 0.

■ [8-04] Domestic hot water tank volume: depending on which
domestic hot water tank is used with the heat pump, the correct
volume must be set:

■ [8-04]=0 when the tank volume is 260 litres (EKHHS260)

■ [8-04]=1 when the tank volume is 200 litres (EKHHS200)

NOTICE

If the setting of [8-04] is not set correctly, customers
might have a hot water shortage when using the auto
adaptive set point. So it is important to set this
correctly!
