•
During heating operation of the unit, the unit will operate to achieve the target water flow temperature set on the user
interface. When weather dependent operation is active, the water temperature is determined automatically depending on
the outdoor temperature.
•
During heating operation of the boiler, the boiler will operate to achieve the target water flow temperature set on the user
interface.
•
Never set the target water flow temperature set point on the user interface above (60°C).
Make sure to correctly configure FOR SERVICEMAN in the user interface. Refer to 10.7 Field settings/Other heating
source.
Ensure that return water to the heat exchanger does not exceed 60°C. Never put the target water flow temperature set
point on the user interface above 60°C.
Make sure that the non-return valves (field supply) are correctly installed in the system.
The supplier will not be held liable for any damage resulting from failure to observe this rule.
8.5 Application 5
Dual setpoint function application with two room thermostat connect to the outdoor unit.
•
Space heating with two room thermostat application through floor heating loops and fan coil units. The floor heating loops
and fan coil units require different operating water temperatures.
•
The floor heating loops require a lower water temperature in heating mode compared to fan coil units. To achieve these
two set points, a mixing station is used to adapt the water temperature according to requirements of the floor heating loops.
The fan coil units are directly connected to the unit water circuit and the floor heating loops are after the mixing station. The
mixing station is controlled by the unit (or field supply, controls itself).
•
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). More details refer to 10.7 field setting /
ROOM THERMOSTAT.
The wiring of room thermostat 5A (for fan coil units) and 5B (for floor eating loops) should follow 'method C' as described
in 9.7.6 Connection for other components/For room thermostat, and the thermostat which connect to port 'C' (in the
outdoor unit) should be placed on the zone where floor heating loops is installed (zone B), the other one connect to port
'H' should be placed on the zone where fan coil units are installed (zone A).
