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 in the system. An independent backup heater can be selected and installed in the door.
pump(10) should be controlled by outdoor unit and connect to corresponding port in the outdoor unit(refer to 9.7.6
Connection for other components/For outside circulation pump P_o).
Circulation pump operation
The circulation pump (1.8) and (10) will operate as long as the unit is on for space heating.
The circulation pump (1.8) will operate as long as the unit is on for heating domestic hot water (DHW).
Space heating
1) The unit (1) will operate to achieve the target water flow temperature set on the wired controller.
2) The bypass valve should be selected so that at all times the minimum water flow as mentioned in 9.4Water piping is
guaranteed.
Domestic water heating
1) When the domestic water heating mode is enabled (either manually by the user, or automatically through scheduling)
the target domestic hot water temperature will be achieved by a combination of the heat exchanger coil and the electrical
booster heater (when the booster heater in the tank is set to YES).
2) When the domestic hot water temperature is below the user configured set point, the 3-way valve will be activated to
heat the domestic water by means of the heat pump. If there is a huge demand for hot water or a high hot water
temperature setting, the booster heater (12.1) can provide auxiliary heating.
