Description
Heat pump HPM is a device used to heat/cool the building and heat the domestic hot
water.
Device is equipped with two units:
- outdoor unit HPMO, compressor heat pump.
Operation of the device is based on taking heat from the environment and forwarding
it to the heating circuit in the building. Low temperature air heat is transferred through
the evaporator into the heat pump system lled a refrigerant, which evaporated turns
to gas. The gas from the evaporator is sucked in by compressor, which raises its
temperature and transfers it when it is compressed to the condenser. In the condenser,
heat is transferred to the medium lling the central heating system, cooled liquid
ows through the expansion valve and goes back to the evaporator, whereupon the
whole process starts again. In the case of cooling, this cycle is reversed and heat is
extracted from the building and discharged outdoor.
- indoor HPMI unit with a built-in heating system controller.
The principle of operation of the device is based on the need-based regulation of
the capacity of the heat pump compressor with the switching of the electric heater
via the internal module controller. The indoor module control unit regulates the
rated power according to the set heating curve. If the heat pump is unable to cover
the building's heat demand on its own, the controller will automatically start the
additional electric heater which, together with the heat pump, produces the required
temperature of the heating medium.

Heating and DHW mode with the heat pump switched off
When the outdoor temperature drops below the set shut-down temperature value,
the heat pump is automatically turned off and cannot produce heating water. In this
case, the heating and DHW mode is automatically performed by the additional electric
heater of the indoor unit.
Automatic defrost
Defrosting of the evaporator surface is done by reversing the refrigerant's circulation.
During the defrosting process the compressed gas is discharged from the compressor
to the evaporator, which melts the existing frost. The heating system cools down
slightly during this time. Duration the defrosting process depends on the degree of
frosting and the current external temperature. Active defrosting process is signaled
on the control panel by the icon .
Transport and storage
The HPMO heat pump should be transported and stored in a horizontal position.
Assembly
The heat pump is designed for outdoor installation and connection to indoor hydraulic
module with integrated additional electric heater. The device must be placed on a solid,
level base or foundation concrete. For fastening, use the attached vibration isolators.
To protect the device against snow and excessive moisture, base or the foundation
should protrude around 300mm above the ground level.
Prepare the ground under the foundation for free drainage of the condensate from
the drip tray. Drainage should be below the freezing zone. The layer thickness and
level must comply with local requirements and principles of construction technique.
The hole diameter should not be less than 100mm.
Condensate drain pipe should be thermally insulated. Thorough leveling the HPMO
outdoor unit will allow for free drainage of the condensate from the drip tray.
The heat pump should not be placed against the wall of rooms where noise could
interfere; e.g. by the bedroom wall. In order to maintain the high eciency of device it
is necessary to keep minimum distance against building's walls and other obstacles.
Restriction of the air ow can lead to the intake of cooled (heated in cooling mode)
air and lead to an increase in energy consumption of the compressor.
Connect the heating medium pipes to the heat pump and hydraulic module.

Connection of outdoor sensors and devices
Circulation temperature sensors (TCRK)
The assembly of sensor was shown on the diagram of hydraulic installation. The
connection cable of the temperature sensor should be as short as possible, it should
not be placed in close proximity to the power cords and twisted around other cords.
Attention, the connection of the sensor is optional, in case of its absence,
circulation pump works continuously according to circulation schedule. If the
sensor is connected, the circulation pump also works according to schedule,
however until the temperature in the circuit is stabilized. The circulation
temperature is checked at certain intervals, if there is a need to raise the water
temperature, then the pump is turned on.
In the absence of a sensor, the pump works continuously, but with connected sensor,
the pump works when the temperature in the circulation circuit drops. System control
automatically detects the presence of the sensor and accordingly adjusts circulation
pump's control algorithm.
Cooling buffer temperature sensor (TBCH)
The sensor mounting location is shown on the diagram of the hydraulic installation with
cooling fan coil. The connection cable of the temperature sensor should be as short as
possible, it should not be placed it in close proximity to the power cords and twisted
around other cords. The sensor is required if the device is congured for cooperation
with fan coil [SERVICE / CONFIGURATION -> Conguration -> Cooling -> Type: Fan coil].
Temperature sensor in the surface heating circuit (TZM)
The sensor mounting location is shown on the diagram of the hydraulic installation.
Sensor is required, if CH2 circuit is active [SERVICE / CONFIGURATION -> Conguration
-> CH2 circuit -> circuit: Yes].
Buffer temperature sensor (TZAS)
Buffer temperature sensor should be placed in the tank's socket.
Room temperature sensor (TPOK)
The connection cable of the temperature sensor should be as short as possible, it should
not be placed in close proximity to the power cords and twisted around other cords.
At a minimum height of 150 cm.

15
EN-102B_f.1296
Outside temperature sensor (TZEW)
The sensor should be mounted in a shaded place, on the north or north-west siede of the
building's facade, away from windows and vents. The connection cable of the temperature
sensor should be as short as possible, it should not be placed in close proximity to the
power cords and twisted around other cords.
Function input 1 (FN1 input)
Opening the input causes the device heating to be blocked. The input is active in winter
mode.
Function input (FN2 input)
Forcing the cooling demand externally. The input is active in summer mode. A short
circuit causes the unit to run in cooling mode as per set parameters.
In order to protect the hydraulic system against condensation, an HP.HS.24 humidity
sensor / switch can be connected to the circuit.

16
Connection to the hydraulic installation
The HPM heat pump can operate in a closed hydraulic installation system (minimum
pressure of the heating medium is 0.6 bar).
Hydraulic installation should be made in accordance with applicable standards. Wires
connecting the heat pump to the indoor module should have an inside diameter of min.
25mm. In order to protect against the transmission of vibrations to the system, exible
hoses must be used to connect the heat pump. Attach the hose to condensate drain.
The heating medium pipes and the drain pipe should be thermally insulated. The outlet
of the drain hose should be placed below depth exposed to freezing.
In case of minus temperatures, do not switch off the device. This will protect the outdoor
unit condenser from damage. If there is a risk of interruptions in the supply of electricity,
the circuit must be separated from hydraulic module by means of an additional heat
exchanger and the heat pump's heating circuit should be lled with glycol.
A prerequisite for maintaining the warranty is the installation of a dirt separator xed
at the inlet to the device.
The hydraulic installation must be made in such a way that the internal HPMI unit can
operate in the heating circuit without external HPMO unit (according to the following
installation diagrams). In case of a failure of the HPMO outdoor unit this will ensure the
functioning of the heating system.

EN-102B_f.1296
Maintenance
Regularly clean the surface of the evaporator from leaves, dust and others. Switch off the
device before cleaning. In order to disable the device, select the Stand-by mode with the
knob and disconnect electric power supply. The evaporator ns are made of aluminium
strips. Do not use hard objects or detergents to clean the evaporator ns containing
chlorine, acids or abrasives; use generally available preparations for cleaning evaporators
and condensers in air-conditioning and cooling installations. After cleaning, check the
condensate drain. While plentiful snowfall, snow can accumulate on the evaporator
and on the top cover of the heat pump. Snow must be cleared to avoid ice formation.
Necessary steps including zero commissioning are:
1. Start-up of the HP heating system and checking its operation (proper setting of
operating parameters and matching them to the properties of the thermal insulation
of the building, installation).
2. Conguration and setting of basic operating parameters (programming room
temperature and DHW).
3. Assessment of the assembly in terms of leaks, disturbing noises (e.g. noise at poor
deaeration).
4. Initial user instruction in the use of the HP system
5. Record the relevant parameters in the Start-up chart form in the HPM.Z operating
instruction.
