UnoFloor Control
Description
The Danfoss UnoFloor Control is a preassembled pressure independent underfloor
heating electronic balancing and control
distribution unit. 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 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.
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.

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

Tender text
Pre-assembled pressure independent underfloor
heating electronic balancing and control distribution unit must come wired and pre-mounted,
suit-able
connection to the manifold, fitted in in-wall
cabinet.
Cabinet must be painted in white (RAL 9016), 750
mm in height, up to 960 mm in width and 110
mm in depth.
It must be possible to connect the room thermostats to the NC/NO actuators via a connection
box. The connection box must have not less 10
chan-nels and 10 actuator outputs, have potential
free relay, one micro disconnection output and
perma-nent 230 V (max 50W) output. Supply
voltage: 230 V AC. Output voltage for actuators:
24 V DC, max. power per output: 2 W. It must be
possible to set up to 10 actuators for 1 room
thermostat. It must be possible to control system
by smartphone app and have presetted work
profiles with applica-tions. Connection box must
have possibility to be upgraded to wireless
solution by Wireless mod-ule. For accuracy
hydronic control, automatic heat load control
feature must be available.
The manifold is used for heat regulation in floor
heating systems. Each circuit in the floor heating
system is connected to the manifold, which
makes it possible to regulate the heat supply
to each room in the building independently.
The manifold shall consist of a flow and return
manifold where the flow manifold must be able
to close each circuit independently. The return
mani-fold must be equipped with presetting
valves, ensuring optimal balancing of the
system. Flow control of the floor heating system
shall be done on a visible presetting scale, so that
the value can be read and checked after
commissioning. Valves shall be controlled
electronically by thermal ac-
for left- and right-hand side
tuators installed without adapters.
The manifold must be provided in modules with
air vent and drain / fill function valve.
The manifold must be made of stainless steel and
have the following specifications:
• Maximum flow temperature : 90 °C
• Maximum differential pressure: 0,6 bar
• Maximum operating pressure: 6 bar
• Max Kv setting of the valve (N): 0,97 m
The actuator must be pre-mounted on a valve.
The actuator receives a signal from the room thermostat. Based on the signal, it opens and closes
the valve which makes it possible to regulate
the energy supply to each room in the building
independently. For easy and secure installation,
the actuator must be delivered as one part (no
adapter) and mounted on the manifold by use of
an Allen screw.
The pressure independent balancing and control
set must consist of a linear control valve, impulse
tube with adapters to it, 3-piece ball valve with
connection to impulse tube and heat meter, connector to manifold . The valve could be used as an
automatic flow limiter. The valve should have a
mechanism to adjust the flow from 100 % to 0 %
of the maximum flow. Maximum recommended
flow setting should not be more than 600 l/h at
maximum system pressure drop 10 kPa, and no
more than 915 l/h at maximum system pressure
drop 5 kPa. Shut off service function should be
possible with setting mechanism. The authority
of the pressure independent control valve should
be 1 at all settings (control valve characteristic is
not changed). Upper limit of pressure controller at
zero flow must be 35 kPa. (Supplier of the valve
should provide lab test results1). Nominal pressure
rating 16 bar.
