Replacing a radiator sensing unit to a wireless Danfoss type

Evaluation of old unit type

Picture of the old sensing unit

Use RA (013G2755)

Sensing unit mounted on valve with SNAP

Consider Sensing unit

New wireless sensing unit

Sensing unit fastened on valve with a hexagon socket screw

Non Danfoss labels E.g. Heimeier and Oventrop Non-Danfoss valve 30 mm

Use RA-K (013G2735)

Sensing unit fastened on valve with union nut Valve

Definitions

Sensing unit

The valve is placed in the piping in the top of the radiator and lets more or less hot water into the radiator

Sensing unit fastened to valve with clamping band with a slot screw 32 mm

Valve The Sensing unit is placed on the valve. In the sensing unit,, a temperature sensor is placed that measures the temperature in the room and ”sends a message” to the valve of how much water it should let into the radiator.

Sensing unit

Use RAVL (013G2795)

Important: External diameter on clamping band = 32 mm

Use RAV (013G2785)

Sensing unit fastened to valve with clamping band with a slot screw ≈ 41 mm

Important: External diameter on clamping band ≈ 41 mm
