7 TYPICAL APPLICATIONS
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 positon of 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 chapter Electrical connections/For outside circulation pump P_o ).
CAUTION
Make sure to connect the thermostat wires to the correct terminals and to configure the ROOM THERMOSTAT in the wired controller
correctly (see field settings/ROOM THERMOSTAT).
Wiring of the room thermostat should follow method A as described in connection for other components/For room thermostat.
Wiring of the 2-way valve (19) is different for a NC (normal closed) valve and a NO (normal open) valve!
Make sure to connect to the correct terminal numbers as detailed on the wiring diagram.
Pump operation and space heating and cooling
The unit will switch to either heating or cooling mode according to the setting of room thermostat.
When space heating/cooling is requested by the room thermostat (5), the pump will start operating and the unit (1) will switch to
heating mode/cooling mode.
The unit (1) will operate to achieve the target cold/hot water leaving temperature.
In the cooling mode. the motorized 2-way valve (19) will close to prevent cold water running through the floor heating loops (FHL).
The ON/OFF setting of the heating/cooling operation cannot be done on the user interface, the target outlet water temperature
should be set in the user interface.
Domestic water heating
Domestic water heating is as described in chapter TYPICAL APPLICATION - Application 2.
