and
NOTE
symbols.
Danger
■
Do not touch water pipes during and immediately after operation
as the pipes may be hot. Your hand may suffer burns. To avoid
injury, give the piping time to return to normal temperature or be
sure to wear proper gloves.
■
Do not touch any switch with wet fingers. Touching a switch with
wet fingers can cause electrical shock.
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.
O
PERATING THE UNIT
I
NTRODUCTION
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 "Field settings" on page 12.
■
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. 113°F (45°C)), and only increase if you feel that the
domestic hot water supply temperature is not sufficient.
■
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 "Programming and consulting the schedule timer" on
page 8.
■
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.

Space cooling operation (c)
In this mode, cooling will be activated as required by the water
temperature set point.
■ The space cooling temperature set point can only be
set manually (refer to "Manual operation" on page 6).
■ 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)
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
dipswitch setting). When necessary and when allowed by the booster
heater schedule timer (refer to "Programming quiet mode, booster
heating or domestic water heating" on page 10), the booster heater
provides auxiliary heating for the domestic hot water tank.
■ 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 6).
■ 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.
Description of the operation modes
Space heating operation (
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 6) or weather dependent (refer to
"Selecting weather dependent set point operation (only in heating
mode)" on page 6).
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.
h)
Powerful domestic water heating operation
In the case of urgent need of domestic hot water, the domestic hot
water temperature set point can be reached quickly by using the
booster heater. Powerful domestic water heating operation is forcing
the booster heater to operate until the domestic hot water
temperature set point is reached.
This function remains available in solar operation.
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 and cooling capacity will also drop.
Beware of this when a certain level of heating is required indoors.

The temperature for heating can be set as low as 59°F
(15°C) (see "Field settings" on page 12). However, the
temperature for heating should only be set lower than 77°F
(25°C) during commissioning of the installation. When set
lower than 77°F (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 "Field
settings" on page 12).
CAUTION
The actual operation range depends on the values set on
field setting [9].
These values shall be determined based on the
application.
In heating mode (h), 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, instead of showing the water temperature set
point, the controller shows the "shift value" which can be
set by the user. 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.

unit after a power supply failure. Press the
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 5.
■ Manually adjust the clock for summertime and
wintertime. Refer to "Setting the clock" on page 5.
■ A power failure exceeding 2 hours will reset the clock

continue operation, but with a disordered clock. Refer
to "Setting the clock" on page 5 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 "Programming and
consulting the schedule timer" on page 8.
What can the schedule timer do?
The schedule timer allows the programming of:
1. Space heating and space cooling (refer to "Programming space
heating or space cooling" on page 9)
Switch on the desired mode at a scheduled time, in combination
with a set point (weather dependent or manually set). Five
actions per weekday can be programmed, totalling 35 actions.
NOTE
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.
p icon displayed) or disabled (p icon
pr button.
pr button
4. Domestic water heating (refer to "Programming quiet mode,
booster heating or domestic water heating" on page 10)
Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.
■ 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.
What can the schedule timer NOT do?
The schedule timer can not change the operation mode from space
cooling to space heating or vice versa.
How to interpret the programmed actions
To be able to understand the behaviour of your installation when the
schedule timer is enabled, it is important to keep in mind that the
"last" programmed command overruled the "preceding" programmed
command and will remain active until the "next" programmed
command occurs.
Example: imagine the actual time is 17:30 and actions are
programmed at 13:00, 16:00 and 19:00. The "last" programmed
command (16:00) overruled the "previous" programmed command
(13:00) and will remain active until the "next" programmed command
(19:00) occurs.
So in order to know the actual setting, one should consult the last
programmed command. It is clear that the "last" programmed
command may date from the day before. Refer to "Consulting
programmed actions" on page 11.
During schedule timer operation, someone may have
altered the actual settings manually (in other words, the
"last" command was overruled manually). The icon
p,
indicating the schedule timer operation, may still be
displayed, giving the impression that the "last" command
settings are still active. The "next" programmed command
will overrule the altered settings and return to the original
program.
2. Quiet mode (refer to "Programming quiet mode, booster heating
or domestic water heating" on page 10)
Switch the mode on or off at a scheduled time. Five actions can
be programmed per mode. These actions are repeated daily.
3. Booster heating (refer to "Programming quiet mode, booster
heating or domestic water heating" on page 10)
Allow or disallow booster heating at a scheduled time. Five
actions can be programmed per mode. These actions are
repeated daily.

Programming and consulting the schedule timer
Getting started
Programming the schedule timer is flexible (you can add, remove or
alter programmed actions whenever required) and straightforward
(programming steps are limited to a minimum). However, before
programming the schedule timer, remind:
■ Familiarise yourself with the icons and the buttons. You will need
them when programming. Refer to "Name and function of
buttons and icons" on page 3.
■ Fill out the form at the very end of this manual. This form can
help you define the required actions for each day. Keep in mind
that:
- In the space heating/cooling program, 5 actions can be
programmed per weekday. The same actions are repeated
on a weekly basis.
- In the domestic water heating, booster heater and quiet
mode program, 5 actions can be programmed per mode. The
same actions are repeated on a daily basis.
■ Ta ke your time to enter all data accurately.
■ Tr y to program the actions in a chronological way: start with
action 1 for the first action and end with the highest number for
the last action. This is not a requirement but will simplify the
interpretation of the program later.
■ If 2 or more actions are programmed for the same day and at the
same time, only the action with the highest action number will be
executed.
■ You can always alter, add or remove the programmed actions
later.
■ When programming heating actions (time and set point), cooling
actions are added automatically at the same time but with the
predefined default cooling set point. Conversely, when
programming cooling actions (time and set point), heating
actions are added automatically at the same time but with the
default heating set point.
The set points of these automatically added actions can be
adjusted by programming the corresponding mode. This means
that after programming heating, you should also program the
corresponding cooling set points and vice versa.
Due to the fact that the schedule timer cannot switch
between operation modes (heating or cooling) and the fact
that each programmed action implies a heating set point
and a cooling set point, the following situations may occur:
■ when the schedule timer is active in heating mode,
and the mode is changed manually to cooling (by
means of the = button), the operation mode will
from then on remain cooling and program actions will
follow the corresponding cooling set points. Returning
to heating mode needs to be carried out manually (by
means of the = button).
■ when the schedule timer is active in cooling mode,
and the mode is changed manually to heating (by
means of the = button), the operation mode will
from then on remain heating and program actions will
follow the corresponding heating set points. Returning
to cooling mode needs to be carried out manually (by
means of the = button).
The above proves the importance of programming both
cooling and heating set points for each action. If you do not
program these set points, the predefined default values will
be used.
