Page 10: Product Specification
. Product specification Product designation The NeoRé series heat pump is designed for heating family houses or smaller industrial buildings. The product is intended for connection to a low-temperature heating system. The ideal heating system is mainly floor, wall and ceiling heating. Connection of conventional wall-mounted radiators is possible, but it is limited by the maximum heating water outlet temperature 55°C. -
Page 11: Outdoor Unit Description
Its heart is a high-quality refrigerant / water exchanger that transfers heat to the heating system. An essential part is the sophisticated Teco controller and its software, which not only controls the operation of the heat pump itself, but also takes care of the thermal comfort inside your building. -

Page 13: Principle Of Operation And Correct Use
. Principle of operation and correct use Principle of heat pump operation The basic prerequisite for the operation of a heat pump is a heat transfer medium with suitable properties for changing the state at a given pressure and temperature. All these basic components are indicated in the figure below – Schematic diagram of the heat pump operation. -
Page 14: Low-Temperature Heating System
Low-temperature heating system Examples of a low-temperature heating system: • floor heating • ceiling heating/cooling • wall heating Large-area radiant systems are best suited for use with a heat pump. The heat pump is maximally efficient with these systems and its service life is longer. They are also the most comfortable type of heating for habitable rooms. With these systems, it is possible to induce natural thermal comfort and avoid heat build-up and large thermal differences upwards, as is the case with traditional convective heating systems. -

Page 38: Faults And Status Messages
. Faults and status messages Error code structure A fault code consists of four digits. The first two digits indicate critical errors. These are faults that cause the heat pump to stop running. The other two digits indicate the status of the connected temperature sensors. Faults of temperature sensors do not affect the operation of the heat pump. -

Fault xxx Low water pressure. If the heating system pressure is lower than .8 bar, the device stops operating in order to avoid damage to the circulating pump. The usual cause is leaking heating water. There may also be damage to the expansion vessel or air leak from its bag. To remove the fault, increase the water pressure in the heating system to . -

is heated continuously to the temperature set by the weather compensation curve for an outdoor temperature of + °C. To correct this, contact a service organization. Status xx x and xx x This status means that the indoor temperature sensor is disconnected or faulty. The indoor temperature sensor is not a standard part of the heat pump installation and it is therefore possible that this status will be displayed permanently. - Page 43 These are protective mechanisms that take care of the safety of the heat pump and protect it from damage or destruction. The following overview lists and explains these safety functions. This list primarily aims to explain the behaviour of the heat pump to the end user or to aid a service organization. In no case it encourages making changes to the product itself or in the service offer.
- Page 44 Water pressure monitoring – heating/cooling water pressure The loss of pressure in the heating system is a serious problem, so when the pressure in the heating system drops below the set value, the entire system stops. The critical pressure value can be set in the service settings under Minimum water pressure . This protection is linked to the autoreset function.

Page 45: Service Organization
Both parameters can be set in the service settings as Restart and Restart Threshold. Cooling water temperature deficit Protection against low water temperature during cooling, when the cooling water temperature drops below the set limit. The limit temperature for shutting down the outdoor unit and cooling is set as the cooling water temperature minus the cooling water temperature deficit. -
Page 46: Maintenance Of The Device And Components
8. Maintenance of the device and components Thanks to its design, the heat pump is easy to maintain. Basic maintenance is to be performed by a service organization during regular annual inspection. During this inspection, the service organization shall check all important parts of the heat pump, especially the operation of the refrigerant circuit. -
Page 47: Maintenance Of The Indoor Unit
Maintenance of the indoor unit The indoor unit requires only minimum maintenance. The device does not contain components that require maintenance by the user. Use only a damp cloth to clean its surface. Take extra care when the device is in operation and powered. We recommend performing maintenance on the indoor unit outside the heating/cooling season in the non-powered state. - Page 48 8. . Magnesium anode rod The service life of magnesium anode protection cannot be precisely determined, because it depends on the quality of the water entering the vessel. Therefore, the protection must be visually checked every six months after commissioning. If a large part of the magnesium anode rod is depleted, replace it with a new one.
