4. OPERATING THE UNIT
4.1. Introduction
The heat pump system is designed to provide you a comfortable
indoor climate for many years at low energy consumption.
To get the most comfort with the lowest energy consumption out of
your system, it is very important to observe the items listed below.
Defining possible schedule timer actions for each day and filling out
the form at the very end of this manual can help you minimize the
energy consumption. Ask your installer for support if required.
■ Make sure the heat pump system works at the lowest possible
hot water temperature required to heat your house.
To optimize this, make sure the weather dependent set point is
used and configured to match the installation environment.
Refer to "5. Field settings" on page 14.
■ It is advised to install the room thermostat connected to the
indoor unit. This will prevent excessive space heating and will
stop the outdoor unit and the indoor circulation pump when the
room temperature is above the thermostat set point.
■ Next recommendations only apply to installations with an
optional domestic hot water tank.
■ Make sure the domestic hot water is only heated up to the
domestic hot water temperature you require.
Start with a low domestic hot water temperature set point
(e.g. 45°C), and only increase if you feel that the domestic
hot water supply temperature is not sufficient.
■ Only for tank with built-in electrical booster heater (EKHW*):
Make sure the domestic water heating by booster heater only
start 1 to 2 hours before you expect domestic hot water
usage.
In case you only need a lot of domestic hot water in the
evening or in the morning, only allow domestic water heating
by booster heater during early morning and early evening.
Also keep hours with low electricity cost tariffs in mind.
To do this, program both the domestic water heating and
booster heating schedule timer. Refer to Programming in
chapter "4.7. Programming and consulting the schedule
timer" on page 10.
■ If the domestic hot water is not used for two weeks or more, a
quantity of hydrogen gas which is highly flammable may
accumulate in the domestic hot water tank. To dissipate this
gas safely, it is recommended that a hot tap be turned on for
several minutes at a sink, basin, or bath, but not at a
dishwasher, clothes washer or other appliance. During this
procedure there must be no smoking, open flame or any
electrical appliance operating nearby. If hydrogen is
discharged through the tap, it will probably make a sound as
of air escaping.

4.5. Description of the operation modes
Space heating operation (h)
In this mode, heating will be activated as required by the water
temperature set point. The set point can be set manually (refer to
"Manual operation" on page 8) or weather dependent (refer to
"Selecting weather dependent set point operation" on page 8).
Startup (d)
At the start of a heating operation, the pump is not started until a
certain refrigerant heat exchanger temperature is reached. This
guarantees correct startup of the heat pump. During startup, icon
d is displayed.
Defrost (d)
In space heating operation or heat pump domestic water heating
operation, freezing of the outdoor heat exchanger may occur due to
low outdoor temperature. If this risk occurs, the system goes into
defrost operation. It reverses the cycle and takes heat from the indoor
system to prevent freezing of the outdoor system. After a maximum
of 8 minutes of defrost operation, the system returns to space
heating operation.
Space cooling operation (c)
In this mode, cooling will be activated as required by the water
temperature set point. The set point can be set manually (refer to
"Manual operation" on page 8) or weather dependent (refer to
"Selecting weather dependent set point operation" on page 8).
INFORMATION
■ Switching between space heating and space cooling
operation can only be done by pressing the =
button or by the external room thermostat.
■ Space cooling operation is not possible if the
installation is a "heating only" installation.
Domestic water heating operation (w)
Only for [4-03]=0, 1, 2, or 3
In this mode, the indoor unit will heat up the domestic hot water tank
by heat pump when the space heating/space cooling operation has
reached its temperature set point or heat pump domestic water
heating has a higher demand request than space side (depends on
DIP switch setting). When necessary and when allowed by the
booster heater schedule timer (refer to "Programming space cooling,
quiet mode, or booster heater mode" on page 12), the booster heater
provides auxiliary heating for the domestic hot water tank.
INFORMATION
■ In order to provide domestic hot water throughout the
day, it is advised to keep the domestic water heating
operation on continuously.
■ The domestic hot water water temperature set point
can only be set manually (refer to "Manual operation"
on page 8).
■ Any domestic water heating operation is impossible
when the domestic hot water tank is not installed.
■ When the w icon is blinking, the domestic hot water is
heating up by the solar kit option and not by the indoor
unit. Refer to installation manual of the EKSOLHW
solar kit.
(1)
Only for [4-03]=4 or 5
In this mode, the indoor unit will heat up the domestic hot water tank.
There are several modes for heating up the domestic water tank:
1. Storage
• Scheduled
The unit will heat up the domestic water tank starting from a
scheduled time and untill the domestic hot water storage set
point is reached. Preferally this is done during nighttime
when space heating demand is the lowest (and if applicable,
electric tariffs are low).
•Powerful
The unit will immediately heat up the domestic water tank
untill domestic hot water storage set point upon user request.
2. Reheat
• Scheduled
The unit will heat up the domestic water tank starting from a
scheduled time and untill the reheat set point is reached.
Preferally this is done during the time of day when space
heating demand is lowest.
• Continuous
The unit will continuously heat up the domestic water tank
untill the reheat set point is reached. In this case a balance
with the space heating demand is made, which ever demand
is higher.
INFORMATION
■ For purpose and configuration refer to "5. Field
settings" on page 14.
■ The domestic hot water storage set point can only be
set manually (refer to "Manual operation" on page 8).
■ The domestic hot water reheat set point can only be
set by the setting [6-07]. Refer to "[6] Scheduled
storage and reheat domestic water heating" on
page 16.
■ Any domestic water heating operation is impossible
when the domestic hot water tank is not installed.
■ When the w icon is blinking, the domestic hot water is
heating up by the solar kit option and not by the indoor
unit. Refer to installation manual of the EKSOLHW
solar kit.
NOTICE
The setting [4-03] shall not be modified. The installer
selected the proper setting for your application.
INFORMATION
The status of this setting is only mentioned to indicate
which settings and functions are applicable for your
application.
[4-03]=0, 1, 2, 3, or 4 is only for domestic hot water tank
with built-in electrical booster heater (EKHW*).
[4-03]=5 is only for domestic hot water tank without
electrical booster heater (EKHTS).
Powerful domestic water heating operation
(2)
In the case of urgent need of domestic hot water, the domestic hot
water temperature set point can be reached quickly by using the
electrical heater. Powerful domestic water heating operation is forcing
the electrical heater to operate until the domestic hot water
temperature set point is reached.
This function remains available in solar operation (only for EKHW*).

Quiet mode operation (s)
Quiet mode operation means that the outdoor unit works at reduced
capacity so that the sound produced by the outdoor unit drops. This
implies that the indoor heating (cooling) capacity will also drop.
Beware of this when a certain level of heating (cooling) is required
indoors.
4.6. Controller operations
Manual operation
In manual operation, the user manually controls the settings of the
installation. The last setting remains active until the user changes it or
until the schedule timer forces another setting (refer to "Schedule
timer operation" on page 9).
As the controller can be used for a wide variety of installations, it is
possible to select a function which is not available on your
installation. In that case the message n will appear.
Switching on and setting space heating (h) and space cooling
(c)
1 Use the = button to select space heating (h) or space cooling
c).
(
Icon h or c appears on the display as well as the corresponding
water temperature set point.
2 Use the bi and bj buttons to set the desired water
temperature.
•Temperature range for heating: 25°C to 55°C
The temperature for heating can be set as low as 15°C (see
"5. Field settings" on page 14). However, the temperature for
heating should only be set lower than 25°C during
commissioning of the installation. When set lower than 25°C,
only the backup heater will operate.
In order to avoid overheating, space heating is not operable
when the outdoor ambient temperature rises above a certain
temperature (as set through field setting [4-02], refer to
"5. Field settings" on page 14).
•Temperature range for cooling: 5°C to 22°C
CAUTION
The actual operation range depends on the values set on
field setting [9].
These values shall be determined based on the
application.
INFORMATION
In heating mode (h) or cooling mode (c), the water
temperature set point can also be weather dependent (icon
a is shown).
This means that the controller calculates the water
temperature set point based on the outdoor temperature.
In this case the controller shows the calculated controller
set point. The bi button or bj button can be used to
display the actual "shift value" and subsequently, to set the
correct value. This shift value is the temperature difference
between the temperature set point calculated by the
controller and the real set point. E.g. a positive shift value
means that the real temperature set point will be higher
than the calculated set point.
3 Switch on the unit by pushing the
y button.
The operation LED 0 lights up.
INFORMATION
When the unit is connected to an external room
thermostat, buttons = and y are not operable and the
icon e is shown. In this case, the external room
thermostat switches the unit on or off and determines the
operation mode (space heating or space cooling).

Schedule timer operation
In schedule timer operation, the installation is controlled by the
schedule timer. The actions programmed in the schedule timer will be
executed automatically.
The schedule timer always follows the last command until a new
command is given. This means that the user can temporarily overrule
the last executed programmed command by manual operation (Refer
to "Manual operation" on page 8). The schedule timer will regain
control over the installation as soon as the next programmed
command of the schedule timer occurs.
The schedule timer is enabled (
not displayed), by pressing the pr button.
INFORMATION
■ Only use the pr button to enable or disable the
schedule timer. The schedule timer overrules the y
button. The y button only overrules the schedule
timer until the next programmed action.
■ If the auto restart function is 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.
■ 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.
It is therefore recommended to leave the auto restart
function enabled.
■ The programmed schedule is time driven. Therefore, it
is essential to set the clock and the day of the week
correctly. Refer to "Setting the clock" on page 6.
■ Manually adjust the clock for summertime and
wintertime. Refer to "Setting the clock" on page 6.
■ A power failure exceeding 2 hours will reset the clock
and the day of the week. The schedule timer will
continue operation, but with a disordered clock. Refer
to "Setting the clock" on page 6 to adjust the clock
and the day of the week.
■ The actions programmed in the schedule timer will not
be lost after a power failure so that reprogramming the
schedule timer is not required.
To set up the SCHEDULE TIMER refer to chapter "4.7. Programming
and consulting the schedule timer" on page 10.

What can the schedule timer do?
The schedule timer allows the programming of:
1. Space heating (refer to "Programming space heating or
domestic water heating" on page 11)
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set).
Four actions per weekday can be programmed, totalling
28 actions.
2. Space cooling (refer to "Programming space cooling, quiet
mode, or booster heater mode" on page 12).
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set). Four
actions can be programmed. These actions are repeated daily.
INFORMATION
When the unit is connected to an external room
thermostat, the schedule timer for space heating and
space cooling is overruled by the external room
thermostat.
3. Quiet mode (refer to "Programming space cooling, quiet mode,
or booster heater mode" on page 12)
Switch the mode on or off at a scheduled time. Four actions can
be programmed per mode. These actions are repeated daily.
4. Domestic water heating (refer to "Programming space heating or
domestic water heating" on page 11)
[4-03]=0, 1, 2, or 3
Switch the mode on or off at a scheduled time. Four actions per
weekday can be programmed, totalling 28 actions.
[4-03]=4 or 5
Switch the mode on or off at a scheduled time. The switch set to
on means enabeling the programmed storage and reheat
operation.
INFORMATION
■ The programmed actions are not stored according to
their timing but according to the time of programming.
This means that the action that was programmed first
gets action number 1, even though it is executed after
other programmed action numbers.
■ When the schedule timer switches space heating or
space cooling x, the controller will also be
switched off. Note that this has no influence on
domestic water heating.
■ [4-03]=4 or 5. In case no domestic water heating
actions are programmed, enabling or disabling the
schedule timer will only have influence on the space
heating, cooling and quite mode. In this way it is
possible to separate on one hand the space heating,
cooling and quite mode scheduled action as part of
the schedule timer and on the other hand the storage
and reheat operation of the domestic water heating.
In this way, it is easy to disable the space heating and
cooling by disabling the schedule timer with keeping
the storage and reheat domestic water heating
enabled (refer to "Scheduled domestic hot water
storage" on page 16 and "Scheduled/continuous
domestic hot water reheat" on page 16).
NOTICE
The setting [4-03] shall not be modified. The installer
selected the proper setting for your application.
