Midi Shunt 088U0181

- with one circuit

The Danfoss oor heating midi shunt is a series of
pre-mounted shunts for one, two or three heating
circuits.
It comes pre-mounted with CF2 master controller,
manifolds, mixing shunt and actuators in a small
and compact solution.

Midi Shunt version For room size Code no.

For 1 circuit, pre-mounted with CF2+ master controller, mixing
shunt with Alpha 2L 15-40 circulation pump, manifold/control
valve and TWA-A 24V NC actuators

For 2 circuits, pre-mounted with CF2+ master controller,
mixing shunt with Alpha 2L 15-40 circulation pump, manifold/
control valve and TWA-A 24V NC actuators

Midi Shunt 088U0182

- with two circuits

Features:

• Compact design - ts in even the smallest
places.

• Pre-mounted - minimal risk of installation
faults.

• Easy ordering - only one number nessecary.

• Short installation time.

• Free choice between four dierent CF2+ ther­mostats (ordered separately).

• Grundfos Alpha 2L pump ensures the lowest
possible operating costs.

RA-N Valve /
FHF Manifold

Midi Shunt 088U0181 has one heating circuit
and is equipped with a Danfoss RA-N pre-setting
valve.
Midi Shunt 088U0182 is equipped with a FHF
manifold with two circuits, and Midi Shunt
088U0183 has a three circuit manifold.
The FHF manifold is used for controlling water
ow in under oor heating systems and consists
of a supply and return manifold.
The supply manifold includes possibility for indi-
