QT is a self-acting thermostatic actuator

designed to be used in combination

with ABQM in one-pipe heating systems.

ABQM together with QT converts

a one-pipe heating system into an

energy eﬃcient variable ﬂow system,

where ﬂow in the risers is dynamically

adjusted to match the load in the riser

by control of return water temperature.

QT is dedicated to be used with ABQM

automatic balancing and control valve.

ABQM together with QT is a complete

one-pipe solution: ABQT.
