ATIONS

Always follow first and foremost the connection diagram 

provided by the HVAC designer or heat pump manufacturer. 

Also read the duct radiator manual. 
The accompanying figure shows an example of the 

arrangement for connecting the heating/cooling radiator unit 

to the heat collection circuit.
Connect the radiator output pipe to the heat collection 

circuit return pipe. Direct the fluid returning from the radiator 

unit to the heat collection circuit return pipe. If you know 

that there is a large loss of internal pressure inside the heat 

pump, the heat pump should be bypassed. If this is done, 

the fluid circuit will come into operation when the heat pump 

comes to a halt. When this happens the pressure loss in the 

one-way bypass valve Y2 must be lower than the pressure 

loss in the heat pump.

Heating:

 The pump starts when the outdoor air temperature 

drops below the winter limit value set at the factory (-5 °C).

Cooling 

The supply air setpoint value for the active mode 

(for example, At home) controls the pump start-up. The pump 

starts when the supply air setting is below the temperature 

of the supply air that is blown into the apartment.
The duct radiator can be installed in both the supply air 

duct and the outdoor air duct. If the radiator is installed in 

the outdoor air duct, it can be used for both preheating and 

cooling, or for preheating or cooling alone. If the radiator 

is installed in the supply air duct, it can be used only for 

preheating or cooling.
The duct radiator can be set to function either automatically 

or manually. 

•  Automatic

 - In summer, the supply air temperature will 

be maintained at the level specified in the temperature 

setting. In winter, the duct radiator will turn on, when the 

outdoor temperature falls below the winter setting.

•  Manual

 - In summer, the duct radiator will turn on, 

when the outdoor temperature rises above the summer 

setting. In winter, the duct radiator will turn on, when the 

outdoor temperature falls below the winter setting.

To prevent the risk of condensation in the supply air 

duct, you can set the adjustment of the supply air limit to 

automatic or manual. 

•  Automatic

 - The supply air limit is adjusted automatically 

based on the dew point of the extract air. When the 

supply air temperature falls too low, the duct radiator will 

turn off.  

•  Manual

 - The supply air limit can be set manually. When 

the supply air temperature falls down to the set value, 

the duct radiator will turn off.

If an external sensor is in use, it is selected from the settings 

of the external sensor whether it is used to control the 

outdoor air duct radiator or the supply air duct radiator.

NOTE:

 If the duct 

radiator is used in 

the supply air duct, it 

can only be used for 

cooling. 

NOTE:

 When used to 

control the outdoor air 

duct radiator, the exter-

nal NTC sensor is ins-

talled in the outdoor air 

duct before the radiator. 

When used to control 

the supply air duct ra-

diator, the external NTC 

sensor is installed after 

the radiator.

NOTE:

When selecting the 

relay (C), take account 

of the maximum 

allowed combined 

power supply (6W) of 

the circuit board in the 

external MV electrical 

box, if the relay power 

supply comes from the 

circuit board’s +24V 

connector.

NOTE:

Due to the risk of humi-

dity damage, in a duct 

that has not been insu-

lated for condensation 

the supply air tempera-

ture must not fall below 

+16 … 20 °C.
