Premounted Midi Shunt
Application |
|
The Danfoss Midi shunts are used for control of flow |
||||
|
|
and supply temperature in hydronic floor heating |
||||
|
|
systems. The compact, midi shunt comes pre- |
||||
|
|
mounted for 1-circuit ready to mount on the wall |
||||
|
|
and fittings for pipe connection (20 × 2 mm). |
||||
|
|
The shunts self-acting proportional thermostatic |
||||
|
|
control valve is used to control the supply |
||||
|
|
temperature. |
|
|
|
|
|
|
The thermostatic sensor ensures that the desired |
||||
|
|
supply temperature to the underfloor heating |
||||
|
|
system always remains constant. |
|
|||
|
|
Other components in the Danfoss Midi shunt: |
||||
|
|
• Built-in check valve ensures correct flow direction. |
||||
|
|
• An air-vent on top and a thermometer for trouble |
||||
|
|
shooting and service. |
|
|||
|
|
• RA-N valve with pre-setting to ensure the opti- |
||||
|
|
mal hydronic balance in the system. |
||||
|
|
• UPM3 Auto pump ensures that the energy con- |
||||
|
|
sumption for the system is kept at a minimum. |
||||
|
|
• Danfoss Icon™ Dial 230V thermostat for accurate |
||||
|
|
room control. |
|
|
