UnoFloor Mixing
General description
and application
Ordering
The Danfoss UnoFloor Mixing is a preassembled
pressure independent underfloor heating
balancing and control distribution unit. UnoFloor
comes wired and premounted. UnoFloor Mixing
includes Danfoss Icon™ 230V Wiring Center or
Danfoss Icon™ 24V Master Controller.
The SSM stainless-steel manifold is used for
controlling water flow. Each tube of the floor
heating system is connected to the manifold,
thus making it possible to control water flow
or heat supply to each room in the building
individually.
The AB-PM set ensures optimal hydronic balance.
Flow limitation independent of differential
pressure is now guaranteed.
The Danfoss compact mixing shunt is used for
regulation of flow and supply temperature in
hydronic floor heating systems.

The diagram shows the capacities for each
heating circuit at different presettings of the
manifold valves.
Based on the above calculations and capacity diagram each manifold valve is preset by rotating
the red ring until the correct value on the ring is
in-line with the sight mark on the valve.

The FH-ST safety thermostat is fixed on the tube
and protects floor and system against too high

FTC is a self-acting thermostatic sensor used for
flow temperature control of floor heating.
The water temperature is measured by a surface
sensor. The snap-lock connector of the sensor element secures a firm connection to the valve.
Features:
• Closes on rising sensor temperature.
• Temperature range: 15 °C to 50 °C
