8.1 Application 1
Space heating with a room thermostat connected to the unit.
The application examples given below are for illustration only.
8 TYPICAL APPLICATIONS
Unit operation and space heating
：
When a room thermostat is connected to the unit and when there is a heating request from the room thermostat, the unit will
start operating to achieve the target water flow temperature as set on the user interface. When the room temperature is above
the thermostat set point in the heating mode, the unit will stop operating. The circulation pump (1.7) and (10) will also stop
running. The room thermostat is used as a switch here.
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. Pump_o (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
).

8.2 Application 2
Space heating without room thermostat connected to the unit. Domestic hot water tank is connected to the unit, and the tank is
with solar heating system.
The volume of balance tank(8) should be greater than 40L. The drain valve (6) should be installed at the lowest positon
in the system. 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
).
NOTE
Make sure to connect the thermostat wires to the correct terminals, method B should be selected (see "For room
thermostat" in
9.7.6 connection for other components
). To correctly configure the ROOM THERMOSTAT in the FOR
SERVICEMAN mode see
10.7 Field settings/ROOM THERMOSTAT
.
