Page 33: Faults And Status Messages
6. 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. -
Page 34: Faults And Troubleshooting
rd digit - No fault - Faulty outdoor temperature sensor – the sensor is disconnected - Faulty outdoor temperature sensor – the sensor is short-circuited - Faulty building temperature sensor – the sensor is disconnected - Faulty building temperature sensor – the sensor is short-circuited - Faulty DHW temperature sensor –... - Page 35 The heat pump user interface in the States and faults lists the last ten fault states (codes) of the heat pump. Complete operating data is accessible via the heat pump’s web interface. The controller has the Fault autoreset function. Thanks to this function, the heat pump can resume operation after a critical fault has been removed, e.g.

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 38 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 39 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: Design Documentation
8. Design documentation Connection of the heat pump to the heating system Designing The impact of the quality of the heating system design is as important as the influence of the quality of water or ma- terials used. Insufficient heat transfer fluid flow leads to an increase in condensation temperature and thus a significant deterioration in COP. - Page 46 view has an adverse effect, decreases the temperature capacity of water, increases compression work and causes cavitation noise. Oxygen and carbon dioxide are corrosive and need to be removed from water. Most of the dissolved gases can be removed from the heating system by deaerating. However, it is not possible to remove gases from the circulating water completely.

Page 50: Heating - Range Of Working Temperatures
Heating - range of working temperatures The NeoRé heat pump can operate only within the output water temperature range according to the graph 8. - Working range of output water temperature. The heating system must be designed according to these requirements. The working temperature range must also be taken into account when heating an unheated building (especially in the case of newly completed buildings in winter) and during floor drying. -
Page 51: Floor Drying Program
8. . Floor drying program Floor drying screen (Fig. 8. ) is divided into two parts, the left for adjusting and the right for control. Five time periods can be selected in the table on the left of the screen, while the output water temperature and time range for which the temperature is to be maintained, can be selected for each period. - Page 52 Cooling - range of working temperatures The NeoRé heat pump can only be operated in cooling mode if there is no water condensation on any element of the cooling system. It is therefore only suitable for large area cooling systems such as cooling ceilings, etc. The flooring system can also be used for cooling, but a very limited cooling capacity of such a system is to be expected.
