Limits Of Use - iDM iPUMP A 2-7 Installation Instructions Manual

3 . 17. Limi ts of u se
The heating of other fl uids as heating water is not permitted with the iPump A (for heating water quality, see
page 51). Heat pumps are by nature subjects to limits of use regarding of pressure and temperature (see
diagram). It is not permissible to operate the iPump A outside these limits.
Note:
The following safety devices are included to protect the heat pump against faults:
- High pressure presostat
- Maximum fl ow temperature limitation with automatic reset via the Navigator control
- Starting current limiter via inverter technology and performance adjustment
Heating
The maximum heat pump fl ow temperature is the highest temperature that the heat pump can
produce (depending on the heat source temperature) and is then switched off at this value. Due to
the hydraulic spread over the heat pump and the control-related switching hysteresis, it is not pos-
sible to reach this temperature in the heating circuit or in the water heater. The maximum possible
management temperature depends on the hydraulic design and the confi guration, and is at least 5
K below the maximum heat pump fl ow temperature.
