Table 5.2 also gives a summary on avoiding faults, if these conditions are not adhered to. 

5.3.1 

Permissible temperatures 

Flow temperature 

The heat pump should be operated with a maximum flow temperature of 58° C. If a flow temperature of more 
than  58°  C  is  selected,  the  heat  pump  works  inefficiently.  The  compressor  is  also  very  greatly  overloaded 
and the equipment will keep malfunctioning. 

In general, the flow temperature should actually be adapted to the actual operating temperatures and be set 
as low as possible. 

Brine temperature 

The  brine  temperature  should  not  be  lesser  than  -6°C.  If  the  temperature  is  lesser,  the  device  works 
inefficient and there is danger of freezing of the device. 

5.3.2 

Flow rate 

No flow rate for heating equipment 

If there is no flow rate in the heating equipment, the system will be extremely overloaded until release of the 
safety  device,  in  this  case  the  high  pressure  switch.  The  water  flow  rate  and  system  pressure  should 
therefore be checked. 

No flow rate in the brine system 

If  there  is  no  brine  side  flow  rate,  again  the  system  will  be  extremely  overloaded  until  release  of  the  low 
pressure switch. A freezing of the system and the heat exchanger inside the device may also occur until the 
heat exchanger bursts and then there is a leak of refrigerant. In the worst case, the device is damaged and 
will have to be replaced. The solution here again, is to check the water flow rate and the system pressure as 
well as checking the frost safety (at least -15° C). 

No ground water flow rate (only at W/W-devices) 

Analogous to the missing flow rate in the brine system the device will be extremely overloaded until release 
of the low pressure switch. Moreover, a freezing of the system and the external heat exchanger is possible 
again.  A  compensation  takes  place  by  a  control  of  the  water  flow,  of  the  system  pressure  and  the 
groundwater conveyor system, a cleaning of the filters and an annual maintenance of the under water pump.
