2.7. Operating Limits
TERRA-S/W heat pumps may only be used with heat
conducting media, brine or ground water. Other heat
conducting media are not allowed.
Furthermore, the heating of other liquids as heating
water is not permitted (heating water quality see
Page 25).
By defi nition, heat pumps are subject to pressure
or temperature-dependent operating limits (see dia-
gram).
The operation of the TERRA heat pump outside these
operating limits is not allowed.
Note:
- The following safety mechanisms are provided for
the safety of the heat pump against potential mal-
functions:
- Combined high and low pressure switch with auto-
matic locking or unlocking by switching the system
off and on (after 3 errors within 24 hours).
- Flow maximum temperature limit with automatic
reset via the Navigator Control.
- Start-up current limiter with rotating fi eld monitoring,
motor current monitoring and phase monitoring for
the compressor.
- Internal winding protection in the compressor
