11.1.3 SOURCE
Frost protection for ground source heat pumps.
MIN SOURCE TEMPERATURE
!
Material losses
Never operate the heat pump with source temperatures
below – 9 °C.
When set to OFF, the temperature at the source sensor is not
scanned.
If the actual temperature drops below the minimum source tem-
perature, the compressor is switched off and the idle time is set.
The compressor is enabled again after the idle time has expired
and the fixed hysteresis of 2 K has been exceeded.
This fault MIN SOURCE TEMP is indicated by a flashing warning
triangle on the display screen, and written to the fault list.
The source pump is always started 30 seconds earlier than the
compressor, which starts when there is a heat demand coming
from the heating or DHW side.
Note
The source pump runs on for 60 seconds after the heat
pump has been shut down.
