medium is too high. The information can appear temporarily when high
room and hot water temperatures are set.
Reset condition:
The information is deactivated when the temperature
falls to the permitted level.
14.9.2 TEMPORARY HEAT PUMP STOP E21.RLP
Function:
Activated when the pressure in the refrigerant circuit of the
heat pump becomes too low. If the information appears several times
during a certain time period, the information transforms into a category

Function:
The compressor stops until the hot gas temperature falls
below the set limit. The warning can occur when the heat pump works
close to the lowest permitted outdoor temperature.
Reset condition:
