UnoFloor Heating / Cooling

General description
and application

The Danfoss UnoFloor Heating / Cooling is
a preassembled pressure distribution unit for
4-pipe systems with floor heating and cooling.
UnoFloor comes wired and pre-mounted.

The UnoFloor’s Danfoss Icon™ Master controller
24V is modular heating center for individual
room control. It can be configured as a wired or
wireless system or as a combination, if required.
Can connect up to 10 thermal actuators and
room thermostats.

The SSM stainless-steel manifold is used for
controlling water flow. Each tube of the floor
heating and cooling 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 The AB-PM set ensures optimal hydronic
balance. Flow limitation independent of
differential pressure is now guaranteed.

Together with Danfoss TWA electric
thermoactuators, RA-C valves make up a perfect
combination for control of cooling and heating
circuits.

Features:

• Compact design - fits in even
the smallest places

• In-wall cabinet ensures flush installation

• Pre-mounted - minimal risk
of installation faults

• Easy ordering - only one number necessary

• Short installation time

• Correct heat distribution, even
under partial load

• Reliable hydronic balancing
for lower heating costs

• Auto balancing provided by Danfoss
Icon™ Master controller

• Intuitive touch user interface

• Automatic change over for cooling
controlled by room thermostat

SSM
Floor Heating Manifold

Part of assembly

Pre-setting diagram

The SSM manifold is used for controlling water
flow in under floor heating systems. 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.

Description Type

Manifold set 4 + 4, with flowmeter SSM-4F
Manifold set 5 + 5, with flowmeter SSM-5F
Manifold set 6 + 6, with flowmeter SSM-6F
Manifold set 7 + 7, with flowmeter SSM-7F
Manifold set 8 + 8, with flowmeter SSM-8F
Manifold set 10 +10, with flowmeter SSM-10F
Manifold set 11 + 11, with flowmeter SSM-11F

Manifold,
with flowmeter

Presetting the manifold
valves

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.
