8.5 Application 5

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).

NOTE

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

.

Make sure to correctly configure FOR SERVICEMAN in the user interface. Refer to 

10.7 Field settings/Other heating 

source

.

NOTE

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.

CAUTION

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).

NOTE

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(10) and pump(23.1) 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 and 

For tank loop pump P_d and mix pump P_c

).

The advantage of the dual set point control is that the heat pump will/can operate at the lowest required water flow 

temperature when only floor heating is required. Higher water flow temperatures are only required in case fan coil 

units are operating. This results in better heat pump performance.

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 only when 

there is request for heating from B. The outdoor unit will start operating to achieve the target water flow temperature. The target 

water leaving temperature depends on which room thermostat is requesting heating.

When the room temperature of both zones is above the thermostat set point, the outdoor unit and pump will stop operating.

NOTE

Make sure to correctly configure the room thermostat installation on the user interface. Refer to "

10.7 Field 

settings/ROOM THERMOSTAT

".

It is the installers’ responsibility to ensure that no unwanted situations can occur (e.g. extremely high temperature 

water going towards floor heating loops, etc.)
The supplier does not offer any type of mixing station. Dual set point control only provides the possibility to use two 

set points.
When only zone A requests heating, zone B will be fed with water at a temperature equal to the first set point. This 

can lead to unwanted heating in zone B.
When only zone B requests heating, the mixing station will be fed with water at a temperature equal to the second 

set point.Depending on the control of the mixing station, the floor heating loop can still receive water at a tempera-

ture equal to the set point of the mixing station.
Be aware that the actual water temperature through the floor heating loops depends on the control and setting of 

the mixing station.

8.6 Application 6

Dual setpoint function application without room thermostat connect to the outdoor unit.

Heating is provided 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 buy from the market, controlled by itself).
