Operation and Installation Manual

3.7. Auxiliary pump connection
Connect the auxiliary pump to the connection port (7).
If the unit is to work with a boiler, install the sensor (included with the unit)
for the latter to check the boiler water temperature. When the temperature
at the sensor reaches the preset level, the auxiliary pump starts to supply
heat to the heat coil in the DHW tank until the DHW reaches the preset
temperature. When the auxiliary pump is running, the compressor unit is off.
If the heat pump is to be operated with solar panels, a dedicated PT-1000
sensor must be additionally purchased and connected. The sensor will check
the temperature of the solar panels. Similar to the operation with a boiler,
when the preset temperature is reached at the sensor, the auxiliary pump
starts as configured in the heat pump system settings.
Enable the external heat source management settings in the heat pump controller. Note that the heat pump controller can manage only one
external heat source (e.g. solar panels or a boiler).
The DHW production by the DHW tank can also be managed with the controller of the external heat source (which can be a boiler or solar panels). This
requires installation of the DHW sensor of the external heat source in the sensor port of the DHW tank (to which the heat pump is connected).
Isolate the unit from the mains voltage before servicing. Have the connections wired by a qualified electrician.
3.8. Circulation pump connection
Connect the circulation pump to the connection port (8).
The circulation pump settings must be enabled and
configured in the heat pump controller. Note that the
operation with a circulation pump increases the heat loss of
the DHW tank.
Isolate the unit from the mains voltage before servicing.
Have the connections wired by a qualified electrician.
