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.
As the temperature sensor attached in the user interface is used to detect the room temperature, the user interface
(4) should be placed in the room where floor heating loops and fan coil units is installed and away from the heating
source. Correct configuration should be applied in the user interface (refer to 10.7 field settings/TEMP. TYPE
SETTING). The first setpoint is water temperature which can be set on the main page of user interface, the second
setpoint is calculated from climate related curves, the target outlet water temperature is the higher one of these two
setpoints. The unit will turn off when the room temperature reaches the target temperature.
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 when the room
temperature of zone B is lower than the set point which set in the user interface. The outdoor unit will start operating to achieve
the target water flow temperature.
