Description
2.10. Limits of use
The TERRA SWM must only be used with the heat
media of brine or groundwater. No other heat media
are permissible. In addition, the heating of other
fl
uids
as heating water is not permitted (for heating water
quality, see page 29).
Heat pumps are by nature subject to limits of use
based on pressure and temperature (see diagram).
It is not permissible to operate the TERRA SWM out-
side these limits of use.
Note:
The following safety devices are included to protect
the heat pump against faults:
- electronic high- and low pressure monitoring
- Flow-maximum temperature limiter with automati-
cally reset via the NAVIGATOR 2.0 control
