The operation and configuration of the field water circuit is the responsibility of the installer.
•
We only offer a dual set point control function. This function allows two set points to be generated. Depending on the
required water temperature (floor heating loops and/or fan coil units are required) the first set point or second set point can
be activated. See 10.7 field setting /TEMP. TYPE SETTING.

The volume of balance tank (8) should be greater than 40L. The drain valve (6) should be installed at the lowest
positon of the system.
•
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 (1.7) 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.
