2.1. Application
The WPU heat pump is suitable for:
●heating a home;
●cooling a home;
●heating tap water.

1 1
The WPU heat pump system of Itho Daalderop consists of
the following parts:
1. Source system
2. Heat pump
3. Central heating system
4. Tap water system
2.2. The WPU heat pump - How does it
work?
The WPU heat pump can heat a home and generate hot
domestic water in an energy-efficient way. In order to do
this, the heat pump extracts heat from a source. This heat
is upgraded to a usable level and used for low
temperature heating and/or hot domestic water.
2.2.1. Source system
The following source systems are used by the WPU heat
pump system as sustainable heat source:
Ground
Suitable for:
●WPU 5G i
●WPU 5G c
●WPU 5G kc
Vertical pipes (ground coils) are placed in the ground and
filled with water. This water is circulated by the heat punt
for the drawing or releasing of heat to the ground.
Depending on the energy demand, a deep sounding is
required for each home of between 100 to 200 metres
deep.
District heating
Suitable for:
●WPU 5G co
District heating uses residual heat of an industrial
company, such as a power plant or a waste incineration
plant, for the central heating of water. This heated water
is transported to homes, office buildings or companies
nearby via an underground network of insulated pipes for
heating and/or hot domestic water. This way, energy that
would otherwise have been lost is re-used sustainably.

2.2.2. Heat pump
The WPU heat pump is an electrically powered device, in
which liquid is pumped around in a closed circuit; this
liquid reaches boiling point and evaporates at a low
temperature and low pressure. This liquid is also referred
to as a refrigerant and is in liquid or gaseous state,
depending on the pressure and temperature. The
refrigerant's change from gas or liquid causes heat to be
absorbed or released.
The refrigerant circuit in the heat pump consists of a
compressor C1, an expansion valve EV1 and two heat
exchangers HX1 and HX2.
C1
EV1
HX1 HX2
The refrigerant circuit works as follows:
1. The liquid refrigerant flows from the expansion valve
EV1 to the evaporator HX1. The evaporator is linked to
the source system. Due to the temperature
difference, the refrigerant absorbs the heat from the
heat source and evaporates.
2. The compressor C1 draws in the gas and compresses
it under high pressure, causing the temperature of
the gas to rise further.
3. The gas then enters the HX2 condensor. The
condensor is linked to the storage tank and the
central heating system of the home. Due to the
temperature difference, the heat of the gaseous
refrigerant will be released to the central heating
water or the tap water. In doing so, the gas will cool
down and condensate.
4. The liquid refrigerant cools down even further until
the expansion valve reduces the pressure.
5. After this, the process can start again.
2.2.3. Central heating system
An efficient use of the WPU heat pump requires the use of
supply systems, such as:
●Wall, floor or ceiling heating (pipes incorporated in
wall, floor or ceiling)
●LT-radiators (oversized radiators)
●LV-convectors (larger than standard convectors)
The benefit of wall, floor and ceiling heating is that the
surface is usually much greater than that of a regular
radiator. A relatively low temperature is therefore enough
to transfer sufficient heat to the environment.
In addition to improved efficiency, these low temperature
systems ensure an even heat distribution and create
more comfort.
LT-radiators and LT-convectors are supply systems that
can still emit sufficient heat at a relatively low water
temperature. They have an extra large surface area (often
due to additional slats or connections) or are equipped
with a ventilator, which enhances the convection effect.
When choosing the supply system, make sure that it is
also suitable for the cooling of the home.
2.2.4. Tap water system
Besides heating and cooling the home, the heat pump
also provides hot domestic water. A traditional gas boiler
can quickly supply an unlimited amount of water at high
temperature, but a heat pump cannot. In order to
guarantee a constant temperature, a storage vessel is
required. The heat pump slowly heats up the water in the
storage vessel.
The WPV storage vessels of Itho Daalderop were
especially designed fro the WPU heat pump, whereby the
power and temperature are harmonised.

2.3. Spider WP Climate thermostat
The Spider WP climate thermostat is a thermostat that
controls the temperature of the room in which it is fitted.
The thermostat is suitable for controlling the WPU heat
pump which can both heat and cool the home. The
connection between the thermostat and the heat pump is
OpenTherm® (wired).
This climate thermostat is unique in that it is also suitable
for controlling your Itho Daalderop ventilation system.
The wireless connection of the ventilation with the
thermostat ensures that you can also control the
ventilation and operate the RF-controls via the
thermostat.

2.4. Zone control
Itho Daalderop Autotemp Spider is an optional zone
control that allows you to control the temperature in
multiple rooms, independently from each other. This
active temperature control ensures that the heating or
cooling is distributed depending on the desired
temperature in each room.
The Spider WP Room thermostat in the living room is the
main thermostat and controls where the home as a whole
is heated or cooled. It is not possible to control the
temperature of each individual room by only using the
main thermostat.
The temperature control in the other rooms is controlled
using their own Spider thermostat. Even when the living
room temperature is at the desired level, Autotemp
Spider makes sure that the desired temperature is also
reached in other rooms. Autotemp Spider can establish a
wireless connection with up to twelve thermostats.

2.5. Application in new-build houses
Each new-build house contains a large amount of
moisture, on average about 4,000 litres. This moisture
comes from wet construction materials, such as
concrete, cement, spray paint and glue. During
construction, rain can also make the construction
materials wet. The best way to get rid of the moisture is
by properly ventilating the home and keeping the
temperature as level as possible.
Forced drying - not too quickly.
By heating the home, you speed up the drying process of
the dwelling, this is also referred to as forced drying of a
home. The forced drying process should not take place
too quickly, as this could cause a lot of damage (such as
shrinkage cracks). It is therefore important to pay a lot of
attention to the forced drying process. Please note that
this forced drying process may take up to six months. Set
the heat to 15 to 18°C, and when you move into the
property to 20°C, Do not turn up the heat any higher, as
this will cause the materials to dry too quickly, damaging
the building construction.
Ventilation during forced drying.
During the drying process, proper ventilation and
circulation of the air are indispensable. Make sure to keep
approximately 5 centimetres of space between the walls
and your furniture during the first year, allowing the
moisture to escape. Open the windows for a while every
day. Furthermore, the mechanical ventilation system
must always be turned on, so never pull the plug. Set the
mechanical ventilation system in the highest position as
much as possible during the first months.
This creates the best possible air circulation in the home.
Energy bill.
Good and continuous ventilation is not only good for our
health, it is an important way of combating moisture
issues in the home. Ventilation causes heat-loss. The
forced drying process of a new-build property also results
in a higher energy consumption and a subsequently a
higher energy bill.
2.6. Recycling
This product was manufactured using sustainable
materials. It should be disposed of in a responsible
manner at the end of its life cycle. Your local authorities
can provide you with information on how to do so.
The product's packaging can be recycled. These materials
should be disposed of in a responsible manner in
accordance with government regulations.
As a reminder of the need to dispose of batteries and
electrical household appliances separately, the product
features a symbol consisting of a crossed-out wheeled
bin. This means that the product should not be disposed
of with the rest of your domestic waste at the end of its
life cycle. It must be taken either to a special separate
waste collection centre operated by the local council or to
an outlet specified by this service.
Any adverse effects on the environment and human
health are minimised by handling batteries and
household appliances separately. This ensures that the
materials comprising the appliance can be recycled,
thereby saving a significant amount of energy and raw
materials.

5. Temperature
5.1. Heating or cooling
Temperature
Heating active
Cooling active
Heating
In a home with a heat pump system, it is recommended to
maintain a constant temperature. You set the thermostat
to a certain fixed temperature and it automatically
determines whether heating or cooling is required. As a
heat pump system is a slow-acting system (slower than a
boiler), and in order to not disrupt the switch between
heating and cooling, it is strongly discouraged to adjust
the temperature daily. If, however, you do wish to make a
minor night adjustment, you can still do so by slightly
adjusting the thermostat. An adjustment by more than 1°C
is therefore not recommended.
The heating temperature is adjustable between 18°C and
24°C.
Cooling in the summer period
Limited cooling of your home is possible during summer.
The room thermostat automatically switches on the
cooling depending on the outdoor temperature and the
desired room temperature. By directing the relatively cold
water from the source through your central heating
system, the heat is extracted from the home and
transported to the source. This gives a cooling effect in
the home as the indoor temperature is reduced to a few
degrees below the outside temperature.
The cooling temperature is adjustable between 20°C and
25°C.
äCaution!
You cannot switch off the COOLING function!
The cooling of the home has another important function,
namely the regeneration of the ground source. This
means that the heat from your home is released to the
ground and stored. This stored heat can be reused for low
temperature heating and/or hot tap water. A heated
source increases the efficiency of the heat pump and
reduces your energy costs.
äCaution!
You must therefore never switch off the heat pump.
Thermostat
To prevent the heat pump from turning on and off
unnecessarily, the thermostat will automatically adjust
the following settings:
●When switching to COOLING, the desired
temperature is increased by 1°C.
●When switching to HEATING, the desired
temperature is lowered by 1°C.
The desired temperature can always be adjusted
manually afterwards.
18

5.2. Increase/reduce temperature
Setting the desired temperature once will suffice for a
pleasant indoor climate. The heat pump will heat or cool
the home based on the set temperature and the season.
The heat pump works at its most economical at a
constant temperature. Lowering the temperature during
the night takes additional energy in a well-insulated
home. Lowering the temperature during the night is
therefore not recommended.

5.3.1. Automatic heating/cooling
By default, the heat pump system will automatically heat
or cool based on the temperature you set. After heating, it
takes at least 24 hours for the system to cool.
5.3.2. Electric heating
By switching on the ELECTRIC HEATING setting, the heat
pump will increase temperature faster in the event of
failure, or to increase comfort. After activating this
setting, the electrical element will switch on for 24 hours,
when necessary, for the additional heating of the home.
After 24 hours, the electrical additional heating switches
off automatically.
The ELECTRIC HEATING setting will result in a higher
energy consumption, which will result in a higher energy
bill.
If ELECTRIC HEATING is turned on, you'll see the letters
EE every two seconds at the place of the desired room
temperature.
For example:
5.3.3. Stand-by
It is possible to turn off the thermostat's temperature
demand (HEATING or COOLING) indefinitely, for example
during your holiday. To do this, the thermostat must be
set to STANDBY mode.
Although the thermostat's temperature demand is
switched off, the temperature in the home is continuously
monitored so that it doesn't get too cold or too hot. During
the STAND-BY setting, the house is not heated above 18°C
or cooled below 21°C.
äCaution!
After switching off STAND-BY mode, the heat pump
system takes some time to get the house back to its
set temperature.
If necessary, use the ELECTRIC HEATING setting to
reach the desired temperature faster.
If your thermostat is in STAND-BY mode, you'll see two
gray dashes at the place of the desired room
temperature.
For example:
20
