INSTALLATION

System components

P  

Circulation pump. Not included in the delivery. The 

circulation pump must be compatible with the fluid 

used in the heat collection circuit, and its capacity 

must be correct. (For example, Grundfos Magna 1 

25-80).

MV   Solenoid valve. Not included in the delivery. The 

valve that is chosen must be compatible with the 

heat collection circuit fluid (For example,  Danfoss 

032U157131).

T1  

Safety thermostat for preventing the accumulation 

of condensate. Not included in the delivery. T1 is 

used when outdoor air temperature exceeds the 

set limit value. Adjustment range: +10...+30 °C.

T2 

Heating thermostat. Not included in the delivery. 

T2 turns the pump on and opens the solenoid 

valve when the temperature falls below the set limit 

value. Adjustment range: -10...+20 °C.

T3 

Cooling thermostat. Not included in the delivery. 

T3 turns the pump on and opens the solenoid 

valve when the temperature exceeds the set limit 

value. Adjustment range: +0...+30 °C.

L  

Supply air thermometer. Not included in the 

delivery.

K  

Condensing water tube. Not included in the 

delivery.

IP  

De-aerator. Not included in the delivery.

Y  

One-way valve. Not included in the delivery.

Y2   One-way valve. Not included in the delivery. 

The pressure loss must be less than the pressure 

loss of the heat pump.

Installation instructions

Always follow first and foremost the connection 

diagram provided by the HVAC designer or heat pump 

manufacturer. 
Connect the duct radiator output pipe to the heat 

collection circuit return pipe. The fluid returning from the 

duct radiator is directed back to the heat collection circuit 

return pipe. Be sure to take account of the resistance to 

frost of the fluid used in the heat collection circuit (see the 

chart on page 6).
Only appropriate condensate insulation can prevent the 

formation of condensing water on the outside surface of 

the duct. To prevent moisture damage, the outdoor air 

duct must be insulated with 20 mm closed cell condensate 

insulation. 
When a duct radiator is used, it is recommended that the 

supply air duct be located in heated indoor premises (e.g. 

inside a false ceiling). NOTE! The supply air duct must be 

insulated with 20 mm closed cell condensate insulation.
If the pressure loss inside the heat collection circuit of the 

heat pump is known to be high, it is recommended that 

the heat pump 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. 
If the duct radiator is used both for preheating and cooling, 

it must be installed in the outdoor air duct before the 

ventilation unit. In this case, the pump and the solenoid 

valve can be controlled using a MyVallox ventilation unit, 

and no separate thermostats are needed (see the user 

instructions for MyVallox ventilation units). If a MyVallox 

ventilation unit is not used for controlling, thermostats T1, 

T2 and T3 are needed.
If the duct radiator is only used for cooling, it can be 

installed in the supply air duct after the ventilation unit. In 

this case, the heating thermostat (T2) is not needed.
A MyVallox ventilation unit cannot be used for controlling a 

duct radiator that is used for cooling. Instead, thermostats 

T1 and T3 must be used.
NOTE! MyVallox ventilation units can be used for 

controlling the pump and the solenoid valve. In such a 

case, no separate thermostats are needed. (See the user 

instructions for MyVallox ventilation units)
