NOTE
● 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 position of the system. An independent backup heater can be selected and
installed in the door. Pump(10) and pump(23.1) 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 and For
tank loop pump P_d and mix pump P_c).
● The advantage of the dual set point control is that the heat pump will/can operate at the lowest required water flow
temperature when only floor heating is required. Higher water flow temperatures are only required in case fan coil
units are operating. This results in better heat pump performance.
• Pump operation and space heating
The pump (1.8) and (10) will operate when there is request for heating from A and/or B. Pump (23.1) will operate only
when there is request for heating from B. The outdoor unit will start operating to achieve the target water flow temperature.
The target water leaving temperature depends on which room thermostat is requesting heating.
When the room temperature of both zones is above the thermostat set point, the outdoor unit and pump will stop operating.
