UnoFloor Mixing

General description and application

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.

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

•Energy-saving

•Pressure-independent AB-PM valve integrated

•Integrated mixing shunt with safety thermostat and self-acting thermostatic sensor

FH-ST55

Safety thermostat

FTC

Temperature controller

230V / 16A TS 55°C

Electrical connection

The FH-ST safety thermostat is fixed on the tube and protects floor and system against too high temperatures, especially important for wooden floors. The FH-ST thermostat switches off the power supply of the floor heating base unit, when the temperature reaches 55 °C.

By switching off the power supply of the floor heating base unit, the actuators (NC) will close

automatically and the floor heating system is protected.

The FH-ST55 can also be connected to a pump or a zone valve.

Note! The electrical installation must be carried out by an authorized installer only (230 V DC).

Code no.	088U0301
Shut-off temperature	55 °C
Switch difference	4 K
Classification	IP 40 (mounted)

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
