4.1
General
This device is a heat pump for the heating of sanitary water in residential areas and small
business premises. When heating sanitary water, the heat pump also cools the area, from
which air is captured and / or returned to. The heat pump can thus along with heating of sanitary
water, be used for cooling of indoor areas, whereby it has to be emphasized, that the heat
pump will only cool the area, if there is a need to heat the sanitary water.
NOTE
For the highest efficiency and savings, we recommend that you use air from areas
with waste heat (boiler room, laundry room, kitchen, cellar, pantry) as a heat
source and that the air temperature is as high as possible.

The device consists from the device generator (compressor, evaporator, fan,...) and the hot
water tank. The housing of the generator is made of durable plastic and is heat and sound
isolated. The device has two attachments for air channels which enable a remote air intake
and exhaust from neighbouring rooms or the environment. The hot sanitary water tank is
equipped with a piped heat exchanger, which can be connected to an external fossil fuel,
biomass or solar energy collector powered boiler.
Hot Sanitary Water Tank
Sanitary water heater is enamelled with patented technology, heat isolated with polyurethane
and mechanically protected with sheet metal. The tank is serially equipped with a water heat
exchanger that can be connected with a boiler when choosing an alternative or additional heat
source. An Mg anode is also placed into the tank, preventing corrosion of the heater upon
potential mechanical damage to the enamel.
Electric Heater
The device is serially equipped with two electric heaters with a power of 2 x 2 kW, which serves
as an additional or backup heating source.
Along with both already installed heaters, it is possible to install an additional heater into the
hot sanitary water tank with a 6/4" attachment with separate power supply.
Anti-freeze probe
Regulator of heat pump senses the temperature of the vaporizer. In the case, that the
temperature of the vaporizer is below -7 °C, it will perform a safety shutdown of the device for
at least 30 minutes. In such a case, the heat pumps with an electric heater automatically switch
to electric heating and the heat pumps with an attached boiler switch to boiler heating
(circulation pump switch on).
Safety thermostat
The electric heater contains a safety thermostat with a limit at 90 °C. This means that, in the
case that the temperature in hot water tank is exceeded, the power supply will be switched off
and the device will stop operating. To restart the device, call authorised installation technician
who must verify and remove the reason of the safety shutdown of the device.
WARNING
When heating with boiler or solar collectors, you may heat the water in the hot
water tank to a temperature above 95 °C whereby the safety thermostat switches
off. In such a case the thermostat has to be manually reset. To restart the
thermostat, an authorised installation technician must be called.
Boiler water temperature control
Monitoring and heating of water to desired temperature is ensured by the advanced
OPTITRONIC 2 touchscreen regulator.
In regards to the set up desired water heating temperature, the controller, as required, switches
the compressor and fan on or off, and, under certain conditions, also switches the electric
heater or circulation pump of the boiler on or off. The maximal temperature of water heating
that can be set up is 65 °C. Should the temperature in hot water tank increase over 80 °C, the
controller switches off all sources of heat for safety reasons.
Minimal temperature of water in hot water tank is 7 °C.
High pressure cooling system protection
To prevent pressure in the cooling system to get too high and potential damage, related to it,
a high pressure safety switch is installed, which stops the operation of the heat pump in the
case of pressure rising beyond a preset point.
Conditions of operation
Environment temperature must be between -7 °C and +35 °C. The air must be clean with
relative humidity not exceeding 50% at +35 °C. At lower air temperatures, the relative air
humidity may be higher. Devices, placed at higher altitudes above sea level may function less
efficiently due to lower air pressure.

10. Hot sanitary water tank (boiler)
The cooling system of the heat pump is a closed circuit system, within which the refrigerant
R134a circles as a heat exchanger. At lower pressure and lower temperature (e.g. 10°C), the
refrigerant evaporate in the heat pump evaporator, thereby drawing heat from the air. Then, the
refrigerant is compressed to a higher pressure in the compressor, which makes its temperature
rise to the temperature, higher than that of the water in the boiler. The refrigerant then gives
away the heat to the water in the condenser, whereby it liquefies. The expansion of the
refrigerant, which makes the refrigerant pressure and temperature lower to the primary value,
the circular process is concluded. This process is repeated throughout the heat pump operation
time.

6. Installation
The lowest height of ceiling in the room must be 2500. The device is made so that it takes heat
from surrounding air or sucks it through air channels and blows it into neighbouring rooms or
the environment. The device may be installed in the following ways.

Figure 1: Suction and exhaust in the same room (e.g. pantry cooling).
Figure 2: Suction and exhaust in the same room.
Figure 3: Suction and exhaust into neighbouring room (e.g. pantry cooling).
The most common placement of the heat pump is such, that the air is sucked from areas,
where there is a lot of waste heat. This air has a part of its heat removed, then released into
the surrounding. Air in kitchens, laundry rooms, sanitary facilities often contains unpleasant
odours, so it is blown into the environment. Thereby we must be careful that the air flows and
pressures in spaces are evened out, which must be ensured by the projecting engineer for the
ventilation.
WARNING
The device must not be placed where there are harmful substances, which
could damage it, in the air (barns, dangerous substance storage, open air,
etc.).

Minimal spacing of the device:
The device may be placed into a room with or without installing air channels. This influences
minimal spacing from the walls, which depend on the direction of entry and exit of air.
Figure 4: Minimal spacing between walls / ceiling in the case of air intake from the same room
Figure 5: Minimal spacing between walls / ceiling in the case of air intake from other rooms or the
environment
In the case of using air heat from the same room where the device is installed, the room must
be at least 50 m3.

Device Levelling
WARNING
The device must be in a vertical position during operation to prevent potential
leaking of water condensation.
Figure 6: Device levelling
The device has to be levelled as shown on the image above.
6.3
Hydraulic Connection
Hydraulic connection must be carried out in accordance with the valid national and local
regulations, which are in force for the connection of sanitary water tanks. The room with the
device must have a drain below the level of the device for the drainage in the case of a water
spill. The image below shows the proper hydraulic connection of the device.
Should the heat exchanger (heating water) in the water tank not be used for water heating, it
must be filled with an anti-freeze liquid, to prevent corrosion in the exchanger. Only close a full
exchanger at the bottom (equalisation of pressure due to temperature changes).
WARNING
Due to use of different materials on the pipe installation, all connections (cold water,
hot water, circulation, heat exchanger) on the device must obligatorily be
galvanically isolated, or the corrosion of connections within the heat storage may
occur. We recommend galvanic separators from red alloy for each attachment, at
least 2x pipe diameter in length.
WARNING
The water tank is intended for potable water so it must obligatorily comply with the
valid national regulations on potable water, or device damage may occur and the
warranty is nullified.

Air Canal Installation
The device has attachments on left and right for the attachment of air canals, which enables:
 the placement of the device into any room which is spacious enough
 ventilation of desired room
 exhaust of waste air or intake of fresh air from the environment
In the case of air canal use, keep in mind that air pipes and every additional knee represent
additional air resistance and lesser capacity of the device. Table 1 shows maximal permitted
canal lengths. Air canals must be isolated to prevent water condensation on the pipe surfaces.
Figure 8 shows the device with air canal connections. The connections are 45 mm in length
and an outside diameter of Φ250. Access to inner parts is protected with mesh.

Connection of Condensation Outlet
By removing heat from air, condensation of air moisture also occurs in the heat pump.
Depending on air temperature and relative air humidity, the production of moisture from air
varies. In some cases, no moisture will be removed from air and in others, up to 10 litres of
condensed water may be produced.

Connection of External Heating Source (alternative / additional source)
Sanitary water in the water storage tank may be heated with the device generator - heat pump
(primary source) and / or various external heat sources. An external heat source can heat
sanitary water along with the heat pump and perform the function of an additional heat source
or heat water independently instead of the heat pump and perform the function of an
alternative heat source.
A backup source is the heat source that heats sanitary water when the machine generator
does not work (defect) and there is a need for heating of sanitary water. As a backup heat
source, the electric heater, installed in the sanitary water boiler, is used.
An alternative source is an independent heat source, which the device has no influence on,
but can take advantage of its heat to heat sanitary water. The heating condition is a higher
temperature of heated water in the alternative source than the temperature of sanitary water
in the heat storage. The heating takes place with the circulation of heated water from
alternative source through pipe exchanger in the heat storage. Alternative sources can be solar
collectors, wood biomass boiler or a fireplace. The control of flow pump of the alternative
source requires the placement of temperature probe of the alternative source into the
alternative source.
An additional source is the source of heating for which it is expected to be available, when
there will be a need to heat sanitary water in the heat storage. The additional source is
activated in the cases when the device is not operational since environmental parameters (air
temperature or stored water temperature) is outside the operational range of the device or
there is a need for quicker heating and works together with the device. Additional sources can
be an oil / gas / pellets / wood biomass powered boiler, electric heater, etc. Activation of the
additional source is controlled by the device controller.
The device controller automatically controls the operation of circulation pump of the external
source in the case of use thereof (collectors, fireplace, wood biomass boiler...) or additional
source (gas boiler, additional electric heater, wood pellet boiler...). For a proper operation, you
must simply properly connect the circulation pump, temperature probe of the alternative
source, and set the parameters in the device controller.
For a proper electrical connection of the attachments follow the instructions in the chapter
about the electrical connection, and for the setting of the controller, the chapter on operation.
WARNING
Due to use of different materials on the pipe installation, all connections (cold water,
hot water, circulation, heat exchanger) on the device must obligatorily be galvanically
isolated, or the corrosion of connections within the heat storage may occur. We
recommend galvanic separators from red alloy for each attachment, at least 2x pipe
diameter in length.
WARNING
Water used for sanitary water heating through the installed heat exchanger in the hot
sanitary water tank must comply with requirements of standard VDI 2035. The
heating system must be filled with soft water, which contains anti-corrosive and antibacterial substances for prevention of corrosion. Before filling, the heating system
must be cleaned of all impurities.
The heating system must be thoroughly drained of all air. Prevent the intrusion of air
into the system, including diffusion air.

Standby Setup
When water reaches desired temperature, the heating switches off and
enters standby mode until water temperature doesn't drop for the standby
level difference.
Factory setting for standby difference 7 °C.
Setting area: AUTO or 2 °C – 10 °C.
Setting step: 0,1 °C..
Example: Water heating will deactivate after reaching the desired
temperature 55 °C. Heating will reactivate once temperature drops for the
standby difference 7 °C, thus to 48 °C.
Dynamic standby:
In case of setting the standby temperature to AUTO, the standby temperature changes in
regards to the set desired water temperature. If the temperature set is 40 °C, standby
temperature difference is 5 °C, while in the case of water temperature 55 °C and more, standby
equals 10°C. Between temperatures 40 °C and 55 °C the standby temperature difference is
calculated in a linear way between 5 and 10 °C.
Static standby:
Other standby settings are static and are the same for all water temperatures. The minimal
temperature difference is thus 2 °C, and the maximal 10 °C. Factory standby difference is set
to 7 °C.
8.3.15.5

9. Device Operation Setting
9.1 Basic Operation
Compressor is used for primary water heating. The compressor operates in a limited
temperature area of entering air (from -7 °C to 35 °C). Outside this area, the controller shuts
down compressor operation for safety reasons. The compressor may heat water to a maximal
temperature of 65 °C.
9.1.1 Basic Operation Programmes
NORMAL: For heating water to desired temperature (chapter 8.1.3), the device uses
the primary heat source (compressor) whenever it is possible. When the primary heat
source, due to conditions (e.g. entering air temperature) cannot provide enough
power, the device adds the additional power source (e.g. electric heater) to aid in water
heating.
ECO: Water is heated to desired temperature (chapter 8.1.3), with a considered
negative deviation ECO. The final water temperature is lower than in the NORMAL
mode. ECO deviation setting can be found in the user menu (chapter 8.3.4).
COMFORT: Water is heated to desired temperature (chapter 8.1.3) with a considered
positive deviation COMFORT. The final water temperature is higher than in the
NORMAL mode. COMFORT deviation setting can be found in the user menu (chapter
8.3.5)
OFF: The device is off.
9.1.2 Additional Source
When the entering air temperature is outside the work area of the compressor of the device
generator, the water can be heated by the internal electric heater.
NOTE
SETTING: in the menu
ADDITIONAL SOURCE SELECTION (chapter 8.3.15.2) the
internal electric heater is selected
.
9.1.3 Backup Source
In case of a compressor defect, the device automatically switches to backup operation. It heats
water with the internal electric heater to a temperature, set with the basic programme. Thus,
the backup operation is ensured until authorised service arrives and removes the defect.
NOTE
Backup source can also be activated and deactivated manually (chapter 8.3.10).

9.2 Operation With External Source
External heat source is located outside the device (e.g. oil / gas / pellet / wood furnace, solar
collectors, fireplace, external electric heater, etc.).
Additional heat source can heat water together with the generator of the device and performs
the functions of an additional source or heats water independently, instead of the generator
of the device, in the function of an alternative source.
NOTE
SETTING: in the menu
ADDITIONAL SOURCE SELECTION (chapter 8.3.15.2)
select
»external source« or
»electric heater + external source«.
Controller enables two modes of operation:
• Water is heated by device and external source
• Water is only heated by external source - alternative operation
9.2.1 Water Heated by Device and External Source
Water heating to temperature, set with the basic programme, takes place with the device
compressor and external source.
In regards to type of external source, we divide between two operation priorities:
• Priority device generator
• Priority external source
9.2.1.1
Priority Device Generator
This setting is used when an external heat source is available, which the device may activate
via electric signal (oil / gas / pellet / wood furnace, external electric heater). External source is
in the function of additional source.
The machine generator is used to heat water. When the temperature of entry air is outside the
work range of the compressor, the device signals the activation of the external source, which
heats water to the temperature, set with the basic programme.
NOTE
SETTING: in the menu
EXTERNAL SOURCE OPERATION PRIORITY (chapter
8.3.15.8) select parameter

9.2.1.2
Priority External Source
This setting is used when an external heat source is available which the device cannot
influence and which operates independently (firewood furnace, fireplace, solar collectors).
External source is in the function of an alternative source.
Basically, the water is heated by the device generator. When the temperature of external
source is higher than the water temperature in the water tank (chapter 9.2.3), the device
switches off the compressor, starts the circulation pump of the external source and
automatically activates the alternative operation mode (chapter 9.2.2). Water heating takes
place only with external source to the maximal external source temperature (chapter 8.3.15.7).
If the external source temperature drops under the set limit (chapter 9.2.3), the device switches
off the circulation pump of the external source and automatically switches off the alternative
mode. Water heating continues with the compressor.

9.2.2.2
Priority External Source
This setting is used when an external heat source is available which the device cannot
influence and which operates independently (firewood furnace, fireplace, solar collectors).
External source is in the function of an alternative source.
When external source has sufficient heat (chapter 9.2.3), the device activates the circulation pump
of the external source and heating with external source begins.
NOTE
SETTING: in the menu
EXTERNAL SOURCE OPERATION PRIORITY
(chapter 8.3.15.8) select parameter
»Priority external source«.
NOTE
When manually activating
alternative operation mode via basic operation menu
(chapter 8.3.3), the device will not use the compressor to heat water in normal
programmes. In case that the external source temperature drops below the value
of the temperature of water in the hot water tank (chapter 9.2.3), water heating will
be interrupted!
9.2.3 Setting Availability of External Source
The device checks conditions which define when the external source is available or has
enough heat with two methods, depending on control of the external heat source:
External heat source which can be activated via electric signal (oil/ gas / pellet furnace,
external electric heater):
The active mode of operation is "Priority device generator" (chapter 9.2.1.1), (chapter 9.2.2.1).
When a need for external source appears, the device activates it with an electrical signal (while
activating the circulation pump of the external source). Checking of the functioning of external
source is carried out by comparing the external source temperature to the sanitary water tank
temperature. When the temperature of external source is at least 5°C higher than the
temperature of the sanitary water tank, the external source is available and used for water
heating. If after n minutes from activation, the temperature of external source is not higher than
5°C, the external source activation electrical signal switches off for n minutes, then the
activation procedure is repeated. If after three consecutive tries the activation of the external
source is unsuccessful, the device reports error E07, which must be manually acknowledged
(chapter 8.3.1). If alternative operation is manually activated (chapter 9.2.2) the alternative
operation will be interrupted and the water heating will be taken over by the compressor or
backup source.
External heat source which the device cannot influence and which operates
independently (wood furnace, fireplace, solar collectors):
The active mode of operation is »Priority external source« (chapter 9.2.1.2) (chapter 9.2.2.2).
In this operation mode, the device regularly checks the external source temperature. When the
external source temperature is at least 10°C higher than the temperature in the sanitary water
tank, the priority source of heating is the external source (the external source circulation pump
is activated). When the temperature difference falls below 5°C, the external source ceases to
be used for water heating. If alternative operation is manually activated (chapter 9.2.2) the
alternative operation will be interrupted and the water heating will be taken over by the
compressor or backup source.
9.3 Additional Operation Programmes
9.3.1 Quick Water Heating
The quick water heating programme
is intended for quick water heating with the device
generator and selected additional source (chapter 8.3.15.2) at the same time. After reaching
ID.: 17-16-27-1514-02

Water is heated by generator of the device and internal electric heater at the same time.

External source:
Water is heated by generator of the device and external source (if available - (chapter 9.2.3
)).

Internal electric heater + external source:
Water is heated by generator of the device, internal electric heater and external source (if
available - (chapter 9.2.3))
The temperature to which the water is being heated by the programme of quick heating
depends on the programme in which the device operates:

Basic operation programmes:
Water is heated to temperature, defined by programme
COMFORT.

Alternative operation programme:
Water is heated to temperature, set in the menu
MAXIMAL EXTERNAL SOURCE
TEMPERATURE (chapter 8.3.15.7).
9.3.2 COMFORT Plus
In the programme COMFORT Plus
, the water is heated to desired temperature with
consideration of positive deviation COMFORT. All available sources are used for heating
device generator,
internal electric heater and
external source). Deviation setting
COMFORT can be found in the user menu (chapter 8.3.5). The programme offers the quickest
possible sanitary water heating, regardless of the cost of heating.
The programme COMFORT Plus can be activated manually (chapter 8.3.3), by schedule
(chapter 8.3.6) or via external input
(chapter 8.3.15.3).
9.3.3 Anti-freeze Programme
The anti-freeze programme
is activated automatically and ensures that, in the case of a
compressor defect, the system does not freeze. The factory setting is 35 °C.
The water heating programme uses heat from the selected additional source (chapter 8.3.15.2)
NOTE
If
additional source is not selected (chapter 8.3.15.2), or external source is not
available (chapter 9.2.3), the programme will activate
internal electric heater.
9.3.4 PHOTOVOLTAICS
The programme photovoltaics
(PV) is a programme of device operation which heats water
with excess electrical power, obtained through a solar photovoltaic system. The programme
activates when the device receives a PV signal via external input
(chapter 8.3.15.3).
When the PV signal is present,
the device generator heats water to maximal work margin
of the compressor temperature (65°C), and from there on to the set temperature of the
programme photovoltaics (chapter 8.3.15.5) water is heated by the internal electrical heater.
If alternative operation mode is active (chapter 9.2.2), the external source will be used for heating when it is
available (chapter 9.2.3).
