General information
Geothermal heat pump HEATKEG uses the relatively constant
temperature of the Earth (groundwater) to obtain thermal energy.
Today, heat pump manufacturers compete with each other on such
characteristics as appearance, compactness, adaptability to various systems
(water-water, ground-water, water-air). As a result, there is a huge increase
in the cost of the heating system. In this regard, it becomes necessary to
install a compressor that is several times more expensive than the standard
ones used in air conditioners. Such replacements also imply a reduction in
the size of the heat exchangers and, consequently, the use of more
expensive materials and technologies. Among other things, the design of
the plate-type heat exchangers (due to the small distances between the
plates) does not allow such devices to connect to groundwater’s surface.
The HEATKEG heat pump is unique in its segment. It is made of
components that are available on the market. The HEATKEG heating system
is configured to use the thermal energy, which is located underground
(groundwater).
The conventional compressors of the air conditioner installed in
our heat pumps work perfectly thanks to the stable groundwater
temperature.
The "pipe in pipe" heat exchanger allows the HP to be used for
any water quality. A constant temperature of source allows us to simplify
circuit design of the device, while reducing the likelihood of it's failure.
The electronics that control all processes are designed and
manufactured by our specialists. Such electronics protects the system and
allows you to set the desired temperature, and also to control it from your
smartphone.

Operational concept, application, model range
The heat pump ___________ is manufactured according to the
latest achievements of science and technology.
Application.
The heat pump water/water is designed for the space heating by
using: the underfloor heating/walls and radiators of all types. The
temperature of the heat transfer reaches 55°C.
HP can also be used for the heating of hot water (DHW) , domestic
and industrial needs. The temperature in the tank can reach 45°C.
The operation of the heat pump is on the principle of water-
water. For the production of 10 kW of thermal energy, 2-3 kW of electricity
is spent.
Some water from the head well enters the heat pump and, passing
through it, loses temperature, thereby heating the evaporator. The
compressor compresses the heat received from the ground water and
transfers it through the heat exchanger condenser to heating devices
(radiators, heat-insulated floor, fan coil units, warmed walls, etc.)
These head wells are drilled no closer than 15 m from each other.
The first one is closer to the boiler house (1-5 m), the second head well is
much lower in the area.

6
The installation of this heat pump becomes impossible if the
groundwater in this area is too far away, and the groundwater table is 50
m or more.
Also, difficulties in using HP can arise in those regions where
groundwater is too saturated with iron, as it settles on the pipe walls and
prevents the heat transfer. The heat pump throws an error message (i.e.
an evaporator). With the help of a booster, you can clean this device with
nitric or other acid.

Operating instruction (the controller guidance)
The manufacturer guarantees the proper operation of the HP (only
in a case of strict observance of the instruction manual requirements).
4.1 Switching on controller
After the turning on of two circuit breakers in the box (of the heat
pump control), the controller will boot up and start a pause that you can
skip by pressing the button . After that, the heat pump will start
working. Switching of the heat pump on and off is also possible with the
button , without de-energizing the HP.
4.2 Operational mode
During normal, regular operation, the green sensor should flash
.
If the HP fails, the red sensor near the exclamation mark flashes
and an error code is displayed on the controller screen. All
Interpretation of errors is in paragraph (7.3).
The inclusion of this sensor indicates that the
compressor is running. This signal means that the pump is
running. The signal means that the DHW relay is switched on..
A short pressing of the button “down” calls up the
information menu -Temperatures -House, Heat Transfer, Evaporator,

10
Compressor, Evaporator 2, Compressor 2, and the supply pressure.
Returning to the main screen may be done by a short press on any button.

(it’s valid only when the compressor is on)
3- The desired temperature in the house
4- Maximum temperature of the heat transfer
(during DHW operation, ignored)
5- Dialog box
6 - Wi-Fi signal level.
7– The temperature of the hot water supply DHW
4.3 The logic of work. Temperature control
After turning on the power, the HP will heat the room (1) until it
reaches 22℃(3).If the temperature of the radiators (2) reaches 50°C (4),
the heat pump will stop working and turn on a pthat the radiators or the
warm floor will сontinue to heat the room. ause for 12 minutes, after If
during this time the air in the house does not heat up to the setting
temperature of 22°C (3), then the HP will turn on and continue to heat the
air.

11
After reaching the set temperature, the heat pump will turn off and
turn on only after the temperature in the room drops by the set step in
degrees, which are indicated in the Air Hysteresis menu section.
Switching off
It is carried out by a red button on the panel, or by an
automatic machine in the control box for a complete de-
energization of the equipment.
The main setting of the room air temperature is carried out by
long pressing the “right” button and is adjusted by the buttons “up”
and “down” .
Setting the "Maximum temperature of the heat transfer "
is carried out by long pressing the “left” button .
Using the buttons “up” and “down” you can change the value
to a larger or a smaller. The button “OK” is used for confirmation.
At a lower temperature of the heat transfer, the most economical mode of
HP operation is achieved.
Entering the settings menu is carried out as follows:
After turning on the HP power, the controller starts a pause countdown (12
minutes by default), we skip this pause by pressing the button “Ok”.
Then, to enter the menu, press and hold the "OK" button. The turning of
pages is carried out using the “right” / “left” buttons. Moving to the next
line is carried out with the “OK” button. The changing of the numeric or
logical values, you can make with the “up”/” down” buttons.

Importantly! After changing the values, press briefly "OK", and save new
values in a memory, and only after that, you can exit to the main screen by
long pressing the "OK" button.
4.4 Hysteresis setting
In order to set the temperature difference between turning off and
turning on the heating, you need to go to the hysteresis settings (menu
number 2). The menu will contain the hysteresis of the heat transfer (the
radiator temperature) and the hysteresis of
the air (the air temperature in the room). To
set up, you need to press “OK” and
using buttons “up” and “down”
change the values. The air hysteresis menu sets the temperature step. As
soon as the air temperature drops by the specified step, the HP will
automatically turn on and raise the temperature to the specified level, which
is displayed in the main menu section.
4.5 Wi-Fi connection, and online control.
After turning on the heat pump, the controller will automatically
create a Wi-Fi hotspot named HEATKEG. After that, it will be possible to
connect to the controller from any device to enter settings.
To connect to the controller, you must select the Wi-Fi network
called HEATKEG in your device and click CONNECT. After connecting the
device to the HEATKEG network, a page with a menu will appear on the
screen of your device on which you need to press the button (Wi-Fi Scan).

13
The page will display all available
access points. We select the network we
need, and in the lower field we enter the
password from it. After that, (provided that
the password is entered correctly), the
controller will connect to this network and
the signal strength indicator will
appear on the controller screen.
This means that the
controller is connected and transmitting data.
If a smartphone (or any other device) connects to the HEATKEG
access point, but the menu page does not open on its own, then you can
display it manually by entering the address into the browser 192.168.4.1.
If the Wi-Fi router (to which the controller is connected) is turned
off, or the password is changed in it, the controller will not be able to
connect and will start working in access point mode, and will also check
every 10 minutes whether the previous network has been restored If the
network appears, then the connection will occur automatically.
To change
the access point, you need to turn off the old router, then the controller
creates an access point and it will be possible to connect to the new router.
The 7th page of the controller menu contains information with
customer data for entering the system settings via the Internet.
The client ID is displayed:

be saved. After that you can exit from this page with the help of long
pressing .
4.7 Operating delays
Launch time of the equipment delay is described on the page <3>. It
is used to prevent frequent starts of the equipment. This allows you to
increase the life of the compressor. It is recommended to use 10-15
minutes.
The compressor relay delay. It is necessary for preliminary pumping of
the liquid through heat exchangers, and this also reduces the load on the
network, avoiding the simultaneous start of engines.
4.8 Critical compressor and evaporator temperature.
This is set up in the menu on the page <4>. The lower evaporator
temperature threshold is necessary to prevent freezing of the heat
exchanger in case of a poor liquid flow. The evaporator sensor is mounted
on a thick suction tube near the compressor.
The compressor high temperature limit is designed to prevent long
operation of the compressor at high temperature.
The compressor temperature sensor is installed on a thin discharge
pipe near the compressor.
4.9 Voltage correction is described on the page <5>. System voltage is
displayed in volts. It is possible to adjust it to the actual voltage using the
button .

16
There are an upper limit and a lower limit for the voltage in the
network at which the system will generate an error. This error will
automatically reset after 12 minutes. High and low voltage control can be
disabled by setting the maximum and minimum values in the settings.
4.10 Customer’s information
This section of the menu <7> contains information about the name
(login) of the client and the server system. And also, there is the time of
communication with the server.
4.11 DHW mode is described on the page <9>
●DHW function status (on/off).
●Overheating (of the heat transfer/ boiler coil).
●Pause (when boiler coil is overheating, then the HP will dump excess
heat into the radiators for a specified number of seconds)
●
DHW hysteresis (temperature switch-on step)
●DHW temperature (switch-off temperature). This parameter can be set
by the user!
When the mode is on, the temperature in the DHW tank is displayed on the
main screen
When the DHW function is on, the boiler will be heated. After the
temperature in the boiler drops below the set one, the relay (3) turns on. It
will simultaneously turn off the heating circulation pump and turn on the
DHW circulation pump, the HP will heat the boiler, ignoring the setting of
the heat transfer (on the main screen). During the heating of the boiler, if
the heat transfer reaches the overheating temperature, the relay (3) will be
turned off and the HP will heat the house (if required) for a specified amount
of time. After that, it will switch to the boiler heating again until the set
DHW temperature is reached.

17
4.12 Controller modes
There are three controller modes (it is described on the page
№<10>):
1) Simple mode - the standard installation
2) Master Mode - the relay №4 will energize to turn on the auxiliary
or parallel heater.
а) The parallel heater - parallel turning on with the compressor
б) An auxiliary heater - the relay 4 will turn on when the house
temperature drops to twice of the house hysteresis value.
3) Driven mode - the heat pump will work only when the OFF and
G pins are closed. And it will be possible to enter the identifier of the master
controller, in this case, the data of the driven one will appear on the web
page of the master controller.
4.14 Time setting is described on the page <11>
Time and date settings can be set in this menu. The clock
continues to work even when the power is turned off. For this purpose, a
CR2032 battery is installed in the controller. Failures in the watch operation
indicate a dead battery. It is recommended to replace the battery every 3
years.
The number of compressors (one/two)
One compressor - the standard installation
Two compressors - an additional compressor will be controlled.
The controller will require two more sensors (the evaporator-2 and the
compressor-2)
4.15 The page <12>
the pressure switch logic (normally closed and normally open) –
This applies to different types of pressostat.

controller operation logic (heating/cooling)
heating - the standard setting
cooling - the only difference in the logic of operation is that the
compressor and the deep pump will turn off when the air temperature in
the house drops to the set one, (this can be used in passive cold systems
when we dump heat into groundwater or geofield), while the compressor is
switched off by a single-pole compressor circuit breaker.
4.16 Page < 13 >
temperature sensors (together / separately)

Security measures
In the event of a malfunction, you should contact the
appropriate specialist to eliminate the breakdown.
5.1 Some operating errors can lead to personal injury or to
equipment damage:
●do not allow children to play with the appliance or use it without
adult supervision;
●provide access to the device only to those persons who know how
to use it correctly.
Repairs may be carried out only by specially trained and
qualified staff.
Poorly performed repairs can lead to hazardous situations during
the operation and deterioration of the equipment.
Use only original spare parts. Annually carry out an inspection and
make necessary maintenance of the HP. Remember! It should be carried
out only by specially educated and trained specialists.
To prevent the injury during the HP operation, it is necessary
that:
●the system was grounded;
●the electrical cable had an appropriate design and section,
according to SNiP;
●the control box had not been attached to flammable surfaces.
When you are working with electrical elements, it is necessary to
de-energize the entire installation. If the insulation is damaged, the device
must be switched off immediately. After making work on the electrical
installation, it is essential to check the correct direction of rotation of the
heat pump compressor.

20
5.2 High temperatures
There is a risk of burns due to hot surfaces and components.
The risk of burns from a hot liquid. There is a risk of burns from
hot water (when using hot gas cooling and high-temperature heat pumps
up to +65 °C or more).
If there is a refrigerant leak from the heat pump, first of all, you
should turn off the unit, then you must ensure ventilation and leave the
room immediately. After that, it is necessary to contact a specialized
refrigeration company for repair work.
