UnoFloor Metering

General description and application

The Danfoss UnoFloor Metering is

a preassembled pressure independent underfloor heating balancing and control distribution unit. UnoFloor comes wired and premounted. UnoFloor Metering 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.

UnoFloor Metering comes with a domestic water lines and MTCV balancing valve for hot water circulation.

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 DHW metering line with MTCV valve

MTCV balancing valve	The MTCV is a multifunctional thermostatic
	balancing valve used in domestic hot
	water installations with circulation.
	The MTCV provides a thermal balance
	in hot water installations by keeping
	a constant temperature in the system,
	thus limiting the flow in the circulation
	pipes to the minimum required level.

	Technical specifications
		Max. working pressure	10 bar
		Test pressure	16 bar
		Max. flow temperature	100 °C
		kVS at 20 °C	DN15: 1,5 m3/h
		Hysteresis	1,5 K
