PP-005654 V4

Proper operation

1. Proper operation
Air-water Basic heat pump is a compact device for heating the domestic hot. The maximum water temperature the heat pump is capable of heating water is
55°C. However, for energy-saving reasons it is recommended not to set the temperature of domestic hot water above 45°C, as it will result in increased costs
and will cause premature wear of the heat pump’s components. This type of heat pump allows to prepare domestic hot water at minimal cost for up to 4-5
person family (assuming the water consumption will amount to 50 l/person/day, and not all at once).
Water temperature that exceeds 50°C can cause serious tissue damage. Special attention should be paid to avoid burns while the heated water is used by the children, the disabled or elderly people.

1.1. Device description and proper operation
The Basic heat pump contains one heat generator and an electric heater used to collect heat in the accumulator tank and heat it to a desired temperature. The pump incorporates a coil providing an opportunity to connect an external heat source, e.g. a central heating or solar collectors. The heat pump collects heat from the surrounding air and uses it to heat up the water in the accumulator tank. The heat pump can be connected to air ducts, however, their diameter cannot  be lower than 160 mm. During operation the heat pump absorbs moisture from the room air and therefore the condensate generation is a normal phenomenon. The condensate drain pipe is led out of the device and should be directed to  the sewage system. In periods of high demand for energy, hot water heating can be assisted by heater installed within the water tank. Every Basic heat pump is equipped with one spiral coil, which is used to connect additional, external heat sources.
In compliance with (UE) NR 517/2014 i (UE) 2015/2068 device/product containing or dependent on fluorinated greenhouse gases. Refrigerant circulation is hermetically closed.

1.2. Heat pump’s purpose
Basic heat pump is used to receive the energy from the air present in the room or from outside the building (taking into account the recommended inlet
temperature) and transfers the energy to the domestic hot water tank. The device may only be operated by an adult, with no mental or physical limitations.
This person should be trained by the installer and become acquainted with the device’s instruction.
1.3. Improper operation
It is prohibited to:

1. Use fat-containing air.
2. Use the device to heat other liquids than domestic hot water.
3. Install the device: outdoors, in rooms exposed to freezing, in rooms exposed to dust, gases or flammable vapors.
4. Operate the device: with its accumulator tank empty; at a temperature below +7°C.

1.7. Maintenance

1. Check the connection between the plug, socket and earthing wire on a regular basis;
2. In colder regions (below 0°C) while the system is to be shut off for a longer period, drain the water to protect the internal tank against freezing and avoid damage to the heater;
3. Check the magnesium anode every 18 months. The anode replacement is not covered by the warranty services. Keep the receipts of the anode replacements and remember to fill the entries in the warranty card. Regular anode replacements are necessary to maintain the warranty on the tank;
4. If water parameters at outlet are sufficient, it is recommended to set a lower temperature to reduce heat emission, prevent lime scale build-up and to save energy;
5. Before you shut off the device for a longer period of time – disconnect the power supply, drain water from the tank and pipes and close all valves. Check all internal components on a regular basis.
6. Check condensate hose regularly and clean it when there is a need to do so.
7. Pay attention to the patency of ventilation ducts.

1.8. Checking and moving the device
After the device is delivered, check its packaging for any damage. If any damage is found, notify the carrier immediately. When moving the machine, consider the following points:

1. The device is fragile, so handle it with special care. Hold the device upright to avoid damage to the compressor.
2. Device should be carried vertical, to avoid damaging heat pump’s aggregate. (The maximum deviation from the vertical axis is 40°).
3. Before you carry the device, check whether the route to the installation site is free from any obstacles.
4. The device should be carried in its original packaging.

General Information

2.1. General view

2.2. Overall dimensions

2.3. Transportation method

It is not allowed to carry the device horizontally. A deviation from vertical position of up to 40 degrees is allowed, as shown in the figure above.

We recommend moving the Basic heat pump in vertical position (standing) by using belts included with the device. The belts are located between the heat pump and a wooden palette (marked in red on the picture above).

Installation

3.1. Connection diagram for the heat pump’s air ducts

The length of both the outlet and inlet air ducts can not exceed 5 m straight. Each 90° bend shortens the length of the straight air duct by 2 m. When the recommended length of 5 m is exceeded, it is recommended to use  appropriate support fan to assist the flow of air. It is recommended to use non-corrugated air ducts, as corrugated ones could cause unwanted air resistance.
Remember, that cold air flowing through the air ducts can cause moisture condensation from the air. It is dependent on conditions and air characteristics inside the room. It is recommended to insulate air ducts.
To avoid mixing different air streams, minimum distance between the suction duct and air outlet should be 1,5 m!
If the device works using air circulating in the room, then it needs to have proper ventilation system and the room capacity has to be checked.

3.2. Installing the heat pump indoors
The heat pump must be installed in such a way to allow a service technician to maintain the compressor unit and should provide access to at least to one wall of the device. A minimum distance from the wall should be 40 cm. A minimum floor area needed to install the heat pump is 2 x 2 m (4 square meters), while the room height should be above 50 cm. When installing the device without the ducts carrying the air to the outside of the building – provide a minimum room ventilation at a level of 300-365 m3/h (depending on the model).

3.3. Heat pump positioned inside the room

CAUTION! The minimum length between the suction duct and cold air outlet should be at least 1.5 m!
The room needs proper ventilation system, and its capacity should be at least 30 m³.

3.4. Air for the heat pump supplied from the outside and discharged to another room In case of using a heat pump as a mean to cool the rooms you should:
– use an additional fan to assist air flow in the case of larger distances,
– use pipes that meet the ventilation requirements,
– at least once a year clean the evaporator antibacterial.
3.5. Air for the heat pump supplied from the room and discharged outside

CAUTION! Ensure adequate ventilation for the rooms!

3.6. Air for the heat pump supplied from and discharged outside

Make sure that there is proper distance between suction duct and cold air outlet.

3.7. Hydraulic connection
Connecting heater to a heat pump should be handled by a qualified person. Heater should be directly connected to water supply network (with a possibility to disconnect it through a shut-off valve) with pressure not exceeding 1,0 MPa,  while minimum pressure can’t be lower than 0,1 MPa. If the water pressure inside water supply network exceeds 1,0 MPa, it is required to reduce the pressure by using the reducing valve. Safety valve should be installed on the pipe  through which cold water is flowing. Safety valve’s discharge hole has to remain open – connected with the atmosphere. During installation we recommend using expansion vessel which protects from hydraulic shocks.
Connecting additional source to the water heater through coil requires a shut- off valve that allows disconnecting the and check valves which stop heat from escaping the , if it is not heated by an outside heat source. When connecting DHW circulation installation it is required to have a shut-off valve and a check valve. Power pipe for DHW is also required to have a shut- off valve. All connection pipes are required to have insulation.

To empty the it is required to use the drain valve installed by following the diagram.
When connecting the heat pump to domestic water, ensure the appropriate water quality is maintained; in accordance with the required national and local regulations.

4.7.1. Electrical diagram of the device

Electrical wiring connections should be carried out by a qualified electrician with a valid license. This fact should be recorded in the warranty card.
Heat pump has to be protected by residual current fuse and overcurrent fuse.
The device should be connected to the mains with its power cord. The wall socket should be grounded. If any malfunction occurs, shut down the system, disconnect the device from the power supply and contact a service centre.
If power cord is damaged, it should be replaced with a cord recommended by the device manufacturer. Maintenance should be handled by service.

4.7.2. Electrical diagram of the device with connected gas boiler

The gas boiler can be used as an additional heating source in winter and summer. The controller is equipped with 2 modes: Summer and Winter.

• SUMMER MODE (the user starts this mode in the summer season). When this mode is activated, the fan starts 2 minutes before the compressor. If the outdoor temperature is lower than the MINIMUM OPERATING  TEMPERATURE, the heat pump is in STANDBY STATE or the heater / gas boiler is turned on.
  – Contactor (gas boiler) – The controller starts the fan for a period of 2 minutes. If the outside temperature is below 7°C, the contactor is activated (until the set DHW temperature is reached). When the outside temperature exceeds 7°C, the heat pump compressor is activated.

• WINTER MODE (the user starts this mode in the winter season). The function allows to turn on an additional water heating source. The WAITING STATE option is enabled by default.
  – Contactor (gas boiler) – The heat pump heats the water by using an additional heat source, e.g. gas boiler.
  The heat pump controller gives 230 V voltage, depending on the model of the gas boiler, it can be used automatically or indirectly through a contactor.

4.7.3. Electrical diagram of the device with connected PV solar installation

The PV Ready function allows the heat pump to cooperate with a photovoltaic (PV) installation. The connection method depends on the model and manufacturer of the inverter.

4.7.4. Electrical diagram of the device with a maintenance-free titanium anode

The ST53.4 controller has an additional functionality that supervises the work of a maintenance-free titanium anode. The titanium anode is connected to the controller, which monitors proper operation of the anode. The operating status is displayed on the heat pump’s controller.

4.7.5. Connecting additional pump
Plug additional pump to the connector marked as no. 7.

1. Remove the top cover as described in p. 4.4.
2. Unscrew the cover securing the electrical installation.
3. Connect the additional pump / gas boiler.

For stranded conductors, use sleeves or tin plating.
If additional sensor that comes with the device is working with a CH boiler, it needs to be installed in a way to be able to read boiler’s temperature. When sensor’s temperature reaches a certain level(value can be set manually) additional  pump turns on and heat starts being transferred through coil in the water heater until the set temperature is reached. Turning the additional pump on causes the compressing unit to shut down.
If heat pump is connected to solar panels, it is required to buy a dedicated PT-1000 sensor. This sensor monitors solar panel’s temperature. Similar to boiler’s sensor, after reaching set temperature additional heat pump is going to turn on, based on settings.
It is required to activate additional heating source in the heat pump’s controller. Keep in mind that heat pump’s controller is compatible with only one additional heat source (solar panel or boiler).
Water heating in the DHW tank can also be controlled by an additional source’s controller (e.g. boiler, solar). In this case, the domestic hot water sensor from the additional source controller should be placed in the heat pump tank’s sensor cover.
Before taking any action, it is required to disconnect the device from power supply. Electrical wiring connections should be carried out by a qualified electrician.

4.7.6. Connecting circulation pump
Plug circulation pump to the connector marked as no. 8.

1. Remove the top cover as described in p. 4.4.
2. Unscrew the cover securing the electrical installation.
3. Connect the additional pump / gas boiler.

For stranded conductors, use sleeves or tin plating.
It is required to turn the circulation pump on and configure it using the heat pump’s controller. Keep in mind that if circulation pump is on, it affects heat energy losses from the heater.
Before taking any action, it is required to disconnect the device from power supply. Electrical wiring connections should be carried out by a qualified electrician.

Troubleshooting

Check if the water is not heated by another heat source: eg CH , solar collector or an electric heater, which could prevent the heat pump from staring up.

Other heat source is working (solar collector, CH , electric heater).

| Change the settings of the additional heat source / configure the settings. The additional heat source may have a priority of operation (if it is controlled by the heat pump’s controller). By default: CH has a priority; solar collector

has a priority according to the set schedule.

The device is in the wrong operating mode.| | „Installation failure”- this is due to incorrect heat reception from the heat pump (the water is heated by an electric heater). To remove the error go to service settings and delete the control temperature alarm (MENU > SERVICE SETTINGS (code 1111) > DELETE CONTROL TEMPERATURE ALARM). If the

error continues to appear, contact the service.

| „Pressure switch failure”- this is due to exceeding of the allowable working pressures in the system (the water is heated by an electric heater).
Disconnect and then restore the power to the device. If the error continues to appear, contact the service.
„Tank sensor failure”- this is due to sensor damage. The damaged sensor must be replaced – contact the service or purchase the sensor in the online

store.

Tank’s sensor error.| | „Tank’s sensor failure”- caused by mechanical damage or incorrect sensor installation. Check connections in the back of the controller. If the sensor is damaged it needs to be replaced – contact service or buy a new one through the online shop.
Compressor idle time.| | If the compressor is idle for a set amount of time, compressor unit is going to turn on.
The device is outside the fixed working time in the work schedule.| | Change the work schedule settings and check the date and time settings. If the heat pump is set to operate according to the set work schedule, the following icon will appear:
Damaged capacitor or compressor’s thermal switch.| Contact the service.

Too high electricity consumption.

|

Working heater (indicated by a pulsating heater icon).

|

| „ECO+” means the heat pump is supported by the electric heater at higher temperatures. In order to avoid this set the temperature below the ECO-ECO+ threshold.
„Party” mode   means that all possible sources of heat (including electric heater) are activated in this mode so that the tank reaches the set temperature as fast as possible. When the temperature reaches the ECO- ECO+ threshold the heat pump will turn off and only the electric heater will continue to operate. To return to normal operating mode, turn off the „Party” mode (MENU > PARTY MODE > TURN OFF).
„Anti-Legionella” mode  – tank’s disinfection process is on. When the temperature reaches the ECO- ECO+ threshold the heat pump will turn off and only the electric heater will continue to operate. After the disinfection process is complete, the heat pump will return to normal operating mode.
Working circulation pump.| | Check the circulation pump’s settings (if it’s controlled by the heat pump’s controller).

Transfer of heat from the water tank to the CH system.

| Check the CH ‘s connection to the heat pump’s tank. Check valves should be installed near the spiral coil to prevent heat loss from the tank. If no check valves are used, the shutoff valves should be closed during the heat pump’s operation.

Water at the outlet is cold.

| Set water temperature is too low.| Increase the set water temperature.
Damaged bathroom battery.| Check water temperature at a different water outlet, the battery could be damaged.
Incorrect connection of the circulation pump.| Check if the circulation pump is properly connected.
Fault| Probable cause| Solution
---|---|---

The heat pump shuts down before reaching the set temperature.

| The temperature of the intake air is too low.| Change the intake point to a room with high enough air temperature, use another heat source.
Air ducts are too long, obstacles (elbows, chimney), obstructed vents or evaporator.| Adjust the air ducts’ length according to the manual, unblock the air ducts, check evaporator’s condition (clean if necessary).
The heat pump, despite continuous work, does not reach the set temperature.|

Transfer of heat from the water tank to the CH system.

| Check the CH ‘s connection to the heat pump’s tank. Check valves should be installed near the spiral coil to prevent heat loss from the tank. If no check valves are used, the shutoff valves should be closed during the heat pump’s operation.
Loss of heat due to circulation.| If the circulation pump is electrically connected to the heat pump’s controller, check the circulation pump’s settings. Limit the time of work. The following icon indicates if the circulation pump is switched on:
If the circulation pump uses an external power supply then there is no possibility of controlling the time of operation by the heat pump’s controller.
Constant or excessive consumption of hot water.| Check the water’s heating cycle if no water is drawn from the tank.
No hot water outflow.| Running water was cut off.| Check the cold water supply system (check if the valves are open) and the pressure in the installation.
The display is off.| Incorrect power plug connection.| Check the power plug.
No readings from temperature sensors.| Incorrect electrical connection of sensors to the controller.| Check the connection of the connectors at the back of the heat pump’s controller.

Water leakage.

| Leaky hydraulic connections.| Seal the hydraulic connections and check the connection spigots.
Improperly leveled device.| Check if the device is leveled and the drainage of the condensate .
The air ducts are not insulated.| When cold air flows through the air duct, the condensation of water may occur, air ducts should be insulated.
Incorrect positioning of the condensate drain hose.| The said hose should be positioned in a sloped fashion and connected to a sewer or drain grate. Check if the hose is not bent, as it may prevent the flow of water.
Occlusion of the condensate drain hose.| Unblock the drain hose.
Unusual sound during compressor’s startup.| Damaged capacitor, which prevents the compressor from starting up.| Contact the service, the capacitor needs to be replaced.
Unusual sound during heat pump’s operation.| Foreign object obstructing the air flow in the device.| Check the evaporator’s patency, condition of the fan guard and air ducts.
The electric heater does not heat.| Defected thermal switch of the heater.| Check the thermal switch located under the heat pump’s front panel. Thermal switch’s breakout could have been the result of an empty water tank for example.
