The pump (1.8) and (10) will operate when there is a request for heating floor heating loops. The outdoor unit will start operating
to achieve the target water flow temperature. The target water can be set in the wired controller.
If solar energy is set avaliable in the wired controller(refer to 10.7 Field settings/OTHER HEATING SOURCE), the heating of
domestic hot water can be done by either the solar energy kit or heat pump. when the solar energy kit turns on, signal will be
sent to the outdoor unit, then the pump (27) will operate, the heat pump will stop heating for domestic hot water during solar
energy kit operation .
The volume of balance tank(8) should be greater than 40L(for 5~9kW unit, greater than 20L) The drain valve (6) should
be installed at the lowest positon of the system. An independent backup heater can be selected and installed in the
door.
NOTE
Make sure to wiring the solar energy kit(26) and solar pump(27) correctly, refer to “9.6.6 Connection for other
components/For solar energy kit”. User interface should be correctly configured, refer to “10.7 Field settings/OTHER
HEATING SOURCE”.
