Description
Ordering
The Danfoss UnoFloor Basic is a pre-assembled
underfloor heating balancing and control
distribution unit. UnoFloor comes wired and premounted. The UnoFloor’s Danfoss Icon™ 230V
Wiring center can connect up to 14 thermal
actuators and 8 room thermostats. It is provided
with 230V Live circulation pump output and a
potential-free relays for controlling a boiler.
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.
Features:
• Compact design — fits in even the smallest places.
• In-wall cabinet ensures flush installation.
• Heat meter connection set with ball valves.
• Pre-mounted — minimal risk of installation
faults.
• Easy ordering — only one number necessary.
• Short installation time.

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.

Tender text
Pre-assembled underfloor heating balancing and
control distribution unit must come wired and
pre-mounted, suitable for left- and right-hand
side connection to the manifold, fitted in in-wall
cabinet.
Cabinet must be painted in white (RAL 9016),
840 mm in height, up to 800 mm in width and
120 mm in depth.
It must be possible to connect the room thermostats to the NC actuators via a connection box.
The connection box must have not less 8 channels
and 14 actuator outputs, have two potential free
relays: one for the pump and one for the boiler.
Distribution voltage: 230 V AC. Voltage: 230 V AC,
max. power per output: 3 W.
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 manifold 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 actuators 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 m²/h.
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 heat meter connection set must be suitable
for left and right hand side connection to the distributor/collector. Connection set must include
110 mm length meter spool piece with no reducing ¾” connection and flat seals. The connection
to the manifold is 1” flat sealing.
